Glossary Of Terms

The following is a list of common definitions, terms and phrases used throughout this manual as they relate to this CNC router and woodworking in general. Become familiar with these terms for assembling, adjusting or operating this machine. Your safety is VERY important to us at Grizzly!

Axis: Direction of movement. On a three-axis mill-

ing machine, axes are typically X (left-right), Y (front-back) & Z (up-down). Axis directions are described as positive or negative. On this machine, positive movement is defined as movement towards the rear (Y), right (X), and top (Z) of the working envelope.

Ball End (Ball Nose): A cutting tool that has a

rounded cutting arc, where the arc diameter is equal to the cutting diameter.

Ball Screw: Drive system component. The ball

screw is rotated by the servo motor and provides the means for moving the gantry and spindle along the axes.

Bed: The bed of the CNC consists of a welded

steel frame, an extruded aluminum table top, and a tongue-and-groove table top with integrated T-slots.

CAD: Computer aided design. CAD software is

used to create a digital model of a project.

CAM: Computer aided manufacturing. CAM soft-

ware converts CAD models into a toolpath defined by G-code that CNC machines can interpret.

Chip Load: Chip load is the measure of the thick-

ness of chips a tool will cut. Chip load is equal to: Feed Rate ÷ (Spindle Speed X Number of Flutes).

Conventional Cut: Cut that occurs when the

rotation of the cutter moves in opposite direction as the workpiece.

Compression Bit: A cutting tool with a combi-

nation of up and down shear cutting edges. Typically used for cutting laminate material to prevent tear-out on both sides of the sheet.

Down-Cut Bit: A cutting tool with edges that

carve downward on the face of the toolpath. Reduces the potential for tear-out, but requires a slower feed rate.

Dust Shoe: An accessory that channels dust and

debris directly from the cutting tool through an attached dust collection system.

Dwell: Part of an operation in which axis move-

ment stops while the spindle is running and the cutter is within the workpiece. Dwells should be avoided as they can lead to tool and workpiece damage.

End Mill: A cutting tool with a straight end, typi-

cally with spiral flute(s). It creates a channel with a flat bottom perpendicular to the sides.

Feed Rate: The speed at which the cutting tool

moves along a workpiece.

Finish Cut: A 3D toolpath that reduces or elimi-

nates the irregular contours left by a rough cut.

Climb Cut: Cut that occurs when the rotation of

the cutter moves in same direction as the workpiece.

CNC: Computer numerical control. Manufacturing

controlled by a computer via coded instructions.

Collet: Metal collar that holds the cutting tool in

place within a spindle nut.

Model G0895 (Mfd. Since 04/22)

Flutes: The cutting edges or inserts of a router bit

or cutting tool.

Flute Length: The length of the cutting portion on

a router bit or cutting tool.

Form Bit: A bit that carves a standard profile such

as a roundover, ogee, or similar contour.

-7-

Gantry: The structure that straddles the bed and

carries the spindle. It moves the full length of the bed along the Y-axis.

G-Code: A machine language that uses axis

points and commands, which the machine uses to move and perform functions.

Hold-Down: A clamp used to firmly hold a

workpiece or fixture to the table.

Home Position: A fixed point on the machine set

with proximity switches. It is the machine zero point on all axes.

Iron Pipe Size (IPS): Pipe sizing system based

on the inside diameter (ID) of pipe.

Letter Address: The first letter of a G-code

command. Commands with similar functions are usually grouped within the same letter address. For example, the "G" letter address deals with preparatory functions that define the machine's operation, while the "M" letter address handles miscellaneous machine functions such as turning on spindles, pumps, and other auxiliary tasks.

Origin: User designated zero point for a workpiece

from which the router will reference the positioning of all cutting.

Plunge: Distance on the Z-axis that the spindle

and cutting tool moves toward, into, or along the workpiece.

Pocket Toolpath: A toolpath that creates a cavity

in the horizontal surface of a workpiece.

Post Processor: Software function that formats

G-code into machine-specific information.

Soft Limits: Axis limits imposed by the work space

boundaries and based on controller settings and the location of home. An "out of soft limits error" implies that there is not enough room to move in a designated direction based on the positioning of the workpiece.

Spindle Speed: Rotational speed of cutting tool

(RPM).

Spoilboard: Sacrificial material placed under the

workpiece that allows the cutting tool to go past the workpiece to ensure a full, clean cut without damaging the work table. Usually made of MDF.

Servo Motor: DC motor that allows for precise

control of angular or linear position, velocity and acceleration.

Surfacing: The process of leveling the surface of

a workpiece or spoilboard so it is perpendicular to the spindle.

Toolpath: User defined route that the cutter fol-

lows to machine a workpiece.

Tool Deflection: Tool deflection occurs when the

spindle speed and feed rate exert sufficient force to deflect the cutting tool. Deflection leads to excessive wear and chatter, which can shorten tool life and leave unwanted tooling marks on the material.

Tool Setter: A device used to set the zero point

(origin) for the Z-axis.

Up-Cut Bit: Cutting tool with edges that carve

upward on the face of the toolpath. Removes chips from the material, but can pull the material off the bed and splinter the top edge.

Profile Toolpath: A toolpath that cuts along the

profile of a set of vectors. Typically used to cut out the shape of a design.

Proximity Switch: A magnetic limit switch that is

used to find home position.

Rapid:

Rough Cut: Toolpath where initial cut removes

The maximum speed of each axis. Higher

rapid rates decrease machining times.

unwanted material, leaving a rough contour.

VFD: Variable frequency drive that controls the

speed (RPM) of the spindle. Enables the fine tuning of the spindle during the operation of a toolpath.

Working Envelope: The three-dimensional area

that the spindle can travel within while cutting or milling.

Additional Safety for CNC Routers

You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters. You can be blinded or struck by broken cutting tools, wood chips, improperly secured workpieces, or adjustment tools thrown from rotating spindle with great force. To reduce risk of serious injury when operating this machine, heed and understand the following:

UNDERSTAND ALL CONTROLS. Make sure

you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury.

AVOIDING ENTANGLEMENT. DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place, secure, and properly operating. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

WEAR EYE PROTECTION. Always wear safety glasses. This provides protection for your eyes from wood chips or broken cutting tools.

USE CORRECT SPINDLE SPEED. Use proper speeds and feeds for each size and type of cutting tool as recommended by tool manufacturer. This helps avoid injury risk from tool breakage during operation and ensures best cutting results.

FIRE HAZARD. To reduce risk of fire, always use proper feeds and speeds for cutting tool and workpiece type. Avoid operations that dwell in one place. Be aware of signs of fire and keep fire extinguisher nearby. Chips and dust collection can disguise embers and smoke. Prepare a fire safety plan and ensure it is practiced by all operators. Never operate machine unattended unless workspace has a lights-out fire prevention system.

PROPERLY SECURE CUTTER. Firmly secure cutting tool so it does not fly out of spindle during operation.

PROPERLY COLLECT DUST. Only use dust collector to clear chips while spindle is turning. DO NOT clear chips by hand when cleaning. Only use a brush or shop vacuum when spindle/axes are NOT turning or moving.

SECURE WORKPIECE TO TABLE. Secure workpiece to table so workpiece cannot unexpectedly move or spin during operation. NEVER hold workpiece by hand during operation.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform routine inspections and all required maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation.

DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure CNC router is turned OFF, disconnected from power, and all moving parts are completely stopped before changing cutting tools or performing any inspection, adjustment, or maintenance procedure.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately. Do not use damaged tools as they are likely to break apart and could hit user with great speed and force.

Model G0895 (Mfd. Since 04/22)

or equipment damage may occur if machine is not properly grounded and connected to power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

For your own safety and protection of

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

No adapter should be used with plug. If plug does not fit available receptacle, or if

A permanently connected (hardwired) power supply is typically installed with wires running through mounted and secured conduit. A disconnecting means, such as a locking switch (see following figure), must be provided to allow the machine to be disconnected (isolated) from the power supply when required. This installation must be performed by an electrician in accordance with all applicable electrical codes and ordinances.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. A permanently connected machine must be connected to a grounded metal permanent wiring system; or to a system having an equipmentgrounding conductor. All grounds must be verified and rated for the electrical requirements of the machine. Improper grounding can increase the risk of electric shock!

For accurate cutting results and to prevent gradual warping of the table and frame, machine MUST be leveled from side to side and from front to back on both ends. Check the table and frame 24 hours after installation, two weeks after that, and then annually to make sure they remain level.

Leveling machinery helps precision components remain straight and ﬂat during the lifespan of the machine. Components on a machine that are not level may slowly twist due to the dynamic loads placed on the machine during operation.

To level router:

Place level on table and align to either X- or

Y-axis.

Rotate each leveling foot to level machine

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

This machine and its components are very heavy. Get lifting help or

Dust Collection

2. Fit 4" dust hose over dust shoe and secure in place with hose clamp (see Figure 26).

This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.

Minimum CFM at Dust Port: 400 CFM

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

Note: Ensure dust hose is long enough for full range of spindle movement prior to installation.

Dust Shoe

Power Connection

Electrocution or fire can occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use an electrician or a qualified service personnel to ensure a safe power connection.

Before the machine can be connected to the power source, an electrical circuit must be made available that meets the minimum specifications given in Circuit Requirements on Page 15. If a power circuit has not been prepared for the machine, do that now. To ensure a safe and codecompliant setup, we strongly recommend that all electrical work be done by an electrician or qualified service personnel.

Vacuum Pump Power Connection

IMPORTANT: Machines running on 220V

power MUST be in delta configuration. Machines running on 380V power MUST be in wye configuration.

United States customers should ONLY use a 220V delta configuration for their vacuum pumps due to voltage availability in North America. Connecting a vacuum pump with a wye configuration to 220V power will damage the vacuum pump!

During next step, make sure incoming ground wire is connected to correct terminal to ensure machine will be properly grounded (see "GND" in Figure 33). An ungrounded or improperly grounded machine can cause electrocution if live electrical wires make contact with frame or other parts touched by operator.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

• Wet or "Green" Stock: Cutting wood with a moisture content over 20% causes unnecessary wear on the cutter and yields poor results.

• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and can come loose or move unexpectedly when being cut. DO NOT cut workpieces with excessive warping!

Workpiece Inspection

Some workpieces are not safe to cut or may first require modification. workpieces for the following:

• Material Type: This machine is only intended for cutting natural and man-made wood products, laminate covered wood products, and some plastics. Cutting drywall or cementitious backer board creates extremely fine dust and may reduce the life of the bearings. This machine is NOT designed to cut metal, glass, stone, tile, etc.; cutting these materials with this machine may lead to injury or damage.

• Foreign Objects: Nails, staples, dirt, rocks, tramp metal, and other foreign objects are often embedded in wood. While cutting, these objects can become dislodged, break the cutter, or cause workpiece kickback—all of which could fly out and strike the operator or bystanders. Always visually inspect workpiece carefully before cutting it. If foreign objects can not be removed, DO NOT cut the workpiece.

• Large/Loose Knots: Loose knots can become dislodged during cutting operation. Large knots can cause cutter or machine damage. Only use workpieces that do not have large/loose knots or plan ahead to avoid cutting through them.

Before cutting, inspect all

• Minor Warping: Workpieces with slight cupping can be safely supported if cupped side is facing table and workpiece is firmly clamped to table. On the contrary, a workpiece with bowed side facing table will rock during a cut and could cause severe injury.

Choosing Cutter

There are many types of cutters available. Be sure to choose the right one for your application and material. Read all manufacturer instructions before installing and using a cutter.

When choosing a cutter, consider:

Material Type: Most cutters are designed for

specific material. Choose a unique bit for plywood, engineered wood products, hardwood, and composite woods to improve overall results. If a general-purpose bit is needed, a two-flute, upcut, spiral bit is a good choice.

Application: Many design features are best

cut using specific tools. For example:

— Use a V-bit for cutting signs and lettering.

— Use a spoilboard cutter or fly cutter for sur-

facing a spoilboard or finishing a smooth, flat workpiece, such as a counter top.

— Use a form bit to cut a profile with a uni-

form contour, such as an ogee or round over.

Model G0895 (Mfd. Since 04/22)

— Use a chipbreaker or rougher for rough

cuts and quickly removing a large amount of material when the finish does not matter.

-33-

3. Feed and Speed Rates: Feed rate, spindle speed, and number of flutes on the cutter determine chip load. The chip load affects the best diameter bit to use to get the highest quality finish while minimizing wear. Most manufacturers will list the recommended chip load for their cutters.

Depth and Width of Cut: The cutter must be

long enough to reach the maximum plunge depth of the operation and small enough to cut the details of the piece. However, shorter, wider bits will deflect less, leading to more accurate cuts, and they are less prone to wear and breakage.

Finish: If a high-quality finish is a priority,

use a cutter with more flutes. Four-flute cutters work well for this in most cases. Do not forget that number of flutes is a component of calculating chip load.

Chip Displacement: Up-cut bits keep the

workpiece clear of chips, but on composite materials the upward force of the operation will chip and fray the top surface of the workpiece. Down-cut bits leave a smooth finish on the top of the workpiece, but pressing chips down creates more heat during the cut and frays the bottom of the workpiece on through cuts. Compression bits are fluted to cut up on the bottom, and down on the top, compressing the workpiece during a cutting operation. Compression bits are ideal for cutting materials like plywood and other composites.

Changing Cutter

Cutters are sharp! To reduce the risk of being cut, wear leather gloves when handling, installing, and removing cutters from spindle.

Securing Workpieces

The Model G0895 comes with a vacuum table that has 6 vacuum zones separated by T-slots. Workpieces with a wide range of shapes and sizes can be secured using clamps, the vacuum table, or both. Always secure the workpiece to the table to avoid injury and damage to the machine an d cutter.

Clamps are the most consistent method to secure a workpiece, but the vacuum table is an excellent option when cutting a workpiece edge where clamps would normally get in the way. However, a flat surface on the bottom of the workpiece is required to create a strong vacuum seal. For workpieces with rough or uneven bottoms, clamps are required. There is no harm in using both clamps and the vacuum table at the same time.

Using Clamps

Always use at least four clamps when clamping a workpiece to the table.

Items Needed Qty

Clamps .................................................4 or more

To clamp workpiece to table:

1. Clear dust, wood chips, and tools from table

surface and T-slots.

4. Slide T-bolts into T-slots, then adjust wing nuts and hex bolts so clamp plates are higher than workpiece (see Figure 40).

Adjusting

Wing Nuts

T-Bolts Slid Into T-Slots

Figure 40. Clamping workpiece to table.

5. Position clamps so workpiece is stable and

does not rock. Take into consideration axis positions when G-code runs.

Tighten wing nuts until workpiece is secure

and flat against table on all four sides/ corners.

Using Vacuum Table

The vacuum table is an alternate way to hold material to the work surface for cutting. It is especially useful when clamps are in the way or the workpiece is irregular in shape. However, if workpiece does not have a tight enough seal with vacuum table, an alternative method must be used to secure it.

2. Thread hex bolt into clamp plate, then insert T-bolt through clamp plate and thread on flat washer and wing nut (see Figure 39).

To secure workpiece using vacuum table:

Inspect workpiece and ensure bottom of

material is flat. Joint or plane bottom of workpiece if needed.

Note: Porous material and workpieces with

knot holes may not create a tight enough seal for vacuum table to function.

Clear dust, wood chips, and tools from table

surface and T-slots with wet/dry vac or dust collector.

3. Position workpiece on table so that it covers

as few vacuum zones as possible.

4. Only open vacuum valves (see Figure 42) for each zone covered by workpiece. Close all other vacuum valves, and plug all unused vacuum ports.

— If workpiece does not fully cover vacuum

zones it is over, use included gasket tube to seal the outside of the workpiece. Arrange tube on table so it fits just underneath outer edge of workpiece, then cut tube to size (see Figure 41).

Figure 41. Gasket tube cut to size to seal

workpiece to vacuum zone.

Figure 42. Vacuum zone control valves.

Note: Using as few zones as possible and

turning off unused zones will improve vacuum strength and better secure the workpiece to the table.

5. Turn vacuum pump ON.

6. Push edge of workpiece with moderate pres-

sure to verify workpiece is properly secured by vacuum system with enough strength to withstand cutting forces.

— If workpiece is not well secured, repeat

Steps 1–6. If workpiece is still not secure, use hold down clamps to augment vacuum.

— If workpiece does not cover all vacuum

ports in zones it is in, place flat scrap material over uncovered ports.

Model G0895 (Mfd. Since 04/22)

Using a Spoilboard

A spoilboard should be used with any operation in which the cutter cuts completely through the workpiece. Typically, a spoilboard is made of MDF that has been surfaced perfectly flat. Even a new piece of material should be surfaced before use.

Clamping Spoilboard

Clamps can be used in combination with the vacuum table if spoilboard does not create a strong seal with the vacuum table.

Items Needed Qty

MDF (sized for table or workpiece) .................. 1

Clamp Set, Double-Sided Tape, or Wood Screws

................................ As Needed

The vacuum table can be used with an MDF spoilboard that is properly prepared. The vacuum pulls air through the porous spoilboard, causing workpieces to be secured to the top of the spoilboard.

Moisture will swell and warp MDF spoilboards. Using a warped spoilboard will result in damaged or inaccurately cut workpieces and could result in damage to the machine. If liquid is spilled on spoilboard, it must be dried and resurfaced, or replaced.

Preparing a Vacuum Spoilboard

Items Needed Qty

MDF Sealant (epoxy or rubberized paint)

To create a vacuum spoilboard:

1. Surface both sides of MDF to remove at

reused until thickness is reduced to approximately

⁄4" or less.

To clamp a spoilboard:

Clamp surfaced spoilboard to machine

bed using included hold-down clamps (see Figure 43). If vacuum table is used, secure spoilboard as described in Using Vacuum Table on Page 35.

2. Secure workpiece to spoilboard.

Note: Depending on the needs of the

workpiece and G-code, it could be appropriate to use additional hold-down clamps, double-sided tape, or mount the workpiece directly to the spoilboard with screws. If vacuum table is used, the suction through the spoilboard may be sufficient to secure workpiece. Always verify workpiece is secure before beginning work operations.

Adjusting Axis

Positions Manually

Knowing how to manually control axis movement is an essential part of operating the Model G0895. Axes must be positioned manually whenever a work origin is set.

Use axis movement buttons on controller (X+, X-, Y+, Y-, Z+, and Z-) to move axes. See Controller Functions on Page 6 for detailed button descriptions.

Manual axis movement can be performed at two speeds and in three motion modes: Continuous, Step, and Distance.

Manual axis movement allows movement beyond soft limit proximity switches, which can damage the machine. Always be aware of axis locations during manual movement, and be prepared to stop machine if axes move unexpectedly.

Changing Axis Movement Speed

1. Press HIGH/LOW to toggle between fast and

slow speeds.

Changing Axis Movement Mode

1. Press MODE to toggle between Continuous,

Step, and Distance modes.

— In Continuous mode, press and hold axis

movement buttons to move axes. Release button to stop movement.

— In Step mode, press button to move axis

one step. Step size is determined by speed mode.

— In Distance mode, press button to move

axis a user-defined distance. Set distance by toggling to Distance mode, then input distance and press OK. Controller will display current setting.

Homing Axes

Homing the machine returns all three axes to "home" position or the machine-specific zero point. Home is determined by magnetic proximity switches and will not change.

Since all machine movement is calculated from home, always home axes and verify machine parameters before each operation.

To home axes:

Model G0895 (Mfd. Since 04/22)

Press HOME. Verify all axes move to their

farthest positions.

2. Verify all machine parameters listed in Verifying Parameters on Page 30.

-39-

Setting Work Origin

Work origin is the workpiece-specific zero point— the starting point for your toolpath. All three axes need to be zeroed at the work origin before running code for any particular operation.

The Z-axis can be set in relation to either the table surface or the workpiece surface, but it must correspond to what is established in the G-code. If this is not done properly, the cutter may crash into the material or the table, causing damage to the workpiece or the table.

Always set work origin before each unique operation. The work origin of all axes must match the origin of the toolpath established in the G-code. Failure to set the work origin may cause the cutter to crash and damage the workpiece, table, or cutter.

To set work origin:

Clamp workpiece to table, insert cutter, and

load G-code to controller.

To set Z-axis origin using tool setter:

Clamp workpiece to table, insert cutter, and

load G-code to controller.

Place tool setter on top of table or workpiece.

3. Manually move X- and Y-axes so cutter is directly above tool setter (see Figure 44).

Figure 44. Spindle over tool setter.

4. Hold down MENU, then press ON/OFF and

release buttons together. Spindle will lower until it presses button on tool setter, then raise slightly. Z-axis origin is set at base of tool setter.

Manually move X- and Y-axes to toolpath

origin established in G-code.

Manually move Z-axis down to 1⁄8" above

workpiece or table surface (as determined by G-code).

Place piece of paper between cutter tip and

workpiece/table surface. Slowly step Z-axis down while sliding paper until paper cannot move.

Press XY->0 to set X- and Y-axis origin.

6. Press Z->0 to set Z-axis origin.

Model G0895 (Mfd. Since 04/22)

Creating G-Code File

Before operations can be run on the Model G0895, a toolpath must be designed and converted to G-code.

CAM software converts a CAD model into G-code, which defines a toolpath for the project, and then formats the G-code into a machine specific dialect via a post-processor.

This machine does not read advanced formatting. By default, it only runs letter addresses for simple axis movement. Review Changing Advanced Settings on Page 44 for information about turning on additional G-code functions.

An operator could also write G-code manually. Often, this is more efficient than designing and processing through CAD/CAM. In addition, knowledge of G-code is integral to refining toolpaths produced by CAM software.

Items Needed Qty

CAD/CAM Software or text editor ...................... 1

USB Drive 16GB or less

IMPORTANT: DO NOT use a USB drive larger than 16GB. The controller is designed to read USB drives below 16GB capacity.

.................................... 1

To create G-Code:

Load CAD file into CAM software. Take into

consideration what type of material will be cut and what type of cutter will be used. Make note of where you will place clamps.

Run post-processing application to export

G-code.

Note: Use post-processing options specific

to the Model G0895 or the RichAuto A11 controller when available. If a post-processor for this machine is not available, use a postprocessor with minimal formatting.

Do a practice run within software to identify

any areas of concern (double-check feed/ speed rates, depth of cut, and the direction the cutter will be traveling).

Review G-code and simplify it if needed.

Note: Simplifying G-code can significantly

reduce processing time. Different CAM software and different post-processors will write code differently and some operations require a human eye to find the most efficient method. Learning where code can be improved is a matter of practice and experience.

Export G-code to USB drive in .NC, .PLT,

.TAP, or .TXT format.

Cleaning &

To reduce risk of shock or

power before adjustments, maintenance, or service.

Schedule

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

• Loose mounting bolts.

• Damaged or dull cutter.

• Clogged or dirty collet, spindle nut, or spindle collet hole.

Blocked dust collection.

•

• Worn or damaged wires.

Dirty vacuum pump filter.

•

• Dust and debris on vacuum table.

• Any other unsafe condition.

Daily Maintenance

• Check/adjust lubrication level in oiler.

• Clean/lubricate linear guide rails.

Weekly Maintenance

Clean/lubricate rack and pinion gear and

•

metal surfaces.

• Clean/vacuum dust buildup in T-slots.

• Inspect spoilboard for defects and flatness.

Protecting

Cleaning the Model G0895 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth.

Lubrication

By design, the linear guide rails, helical rack and pinion gears, and other metal parts on this machine have hardened surfaces that are highly resistant to corrosion and wear. However, periodically wipe metal parts with light machine oil and synthetic grease (see ACCESSORIES on

Page 47) to extend their life.

Note: Lubrication can cause sludge build-up that

will bind moving parts, and corrosion can still occur if catalysts are trapped beneath lubricant. Always clean surfaces before applying any form of lubrication.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.

EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.
