DEFINITION OF TERMS

A. Tables With Moveable T-Slot Engraving Beds (VISION 16x12 and 16x24)

In this design, the T-slot table moves in the Y-axis direction while the gantry remains xed. The carriage moves from left to right in the X-axis. There are no particular design advantages

or disadvantages to this style of table. The main engineering criteria in the development of this design was the need to minimize the overall table footprint while providing the maximum engraving area.

All mechanical alignments are referenced to this plate, so the space upon which you place the engraving table must be a reasonably level surface.

2. Y-Axis Linear Rails. Mounted on the table base plate are stainless steel rails with sealed

bearings, which allow the motion of the T-slot table in the Y-axis direction.

Chapter 1

3. T-Slot Table. Also referred to as the work surface, this aluminum bed supported by the

linear rails allows placement of the engraving material or special clamps and xtures. The

slots in this table are shaped with an upside-down T, with the bottom of the T being a single-

line slot across the top of the table (see g 1.1b). The slots are used to hold various accessory

holders, clamps, and jigs. All t-slot accessories are avaiable on at ww.visionengravers.com

4. Y-Axis Lead Screw. This is a threaded rod located underneath the T-slot table. Combined with the stepper motor, the lead screw is rotated and causes the T-slot table to move along

the rails in the Y-axis direction (as seen in gure 1.1c). There is also a second lead screw called the X-axis lead screw. The X-axis lead screw is contained within the gantry, and can be accessed by removing the black sheet metal gantry cover. The X-axis lead screw is responsible for X-axis motion of the carriage assembly, moving it left and right across the gantry.

5. Gantry Assembly. The gantry or “bridge” is a large, rectangular bar suspended across

the width of the table in the X-axis. The carriage assembly is supported and rides on the gantry in the X-axis.

6. Carriage Assembly. The carriage assembly houses the engraving spindle, Z-Axis mechanism and engraving motor. The carriage moves along the gantry assembly on a set of sealed bearing. The carriage assembly holds the engraving spindle; it raises and lowers the spindle during the engraving process using a lead screw and stepper motor.

7. 25 Pin Breakout Box. This electrical access is used to connect the table to the system controller. The breakout box and connector are located near the rear of the table and under

the base plate. (see page 13, g 2.1).

8. Y-Axis Stepper Motor. Drives the T-Slot table in the Y-Axis.

9. X-Axis Stepper Motor. Drives the carriage in the X-Axis. Located under the protective

sheet metal cover.

10. Material Guides. Used as a back and side stop for accurately locating material and clamps during set-up.

11. Engraving Motor. Drives the spindle for rotary engraving.

12. Quick-Lock Vise. A “cam” type locking device that allows quick change of parts for

engraving.

(Figure 1.1b) T-slot close up

Page 10

1. Engraving Motor. The engraving motor or “spindle motor”, is the large black motor on

the top of the carriage assembly. The engraving motor drives a belt and pulley system, which turns the engraving cutter during the engraving process.

2. Z-Axis Stepper Motor. The small motor under the carriage cover that provides the spindle up and down motion of the spindle during the engraving process.

3. Spindle Assembly. The spindle mounted in its block; includes a pulley, housing, micrometer, retainer ring, nose cone and associated hardware. The spindle assembly moves up and down along a linear bearing, which attaches to the face of the carriage assembly.

4. Spindle Block. Houses the spindle assembly.

5. Z-Leadscrew. The threaded screw which raises and lowers the spindle during the

engraving process.

6. Engraving Motor Belt. Drive belt connecting the engraving motor to the spindle pulley.

B. Tables With Moveable Gantrys (“Flatbeds”-Vision 24x24, 24x48 on page 12)

The difference in design of the atbed table versus the moving T-slot type is that the atbed work area does not move. In this design, the entire gantry travels the length of the X-axis and the

carriage moves in the Y-axis.

Connection of Power, Cables, and Controllers

Additional boxes may have been shipped along with your table, depending on the system ordered. These will typically include a control unit and associated cables. The proper connection of these cables is essential. Check the appropriate user’s manuals for your controller before attempting to connect them it to the table. After connection of the cables as directed by your controller manual, power can be connected to the system. It is suggested that a surge protector be used.

An “Auxiliary” Power Strip may have been included with your purchase. This strip is used for

automatically starting and stopping accessories via the Vision Series 3 controller’s “AUX ON/ OFF” button. Typical uses include: Vacuum Systems, Air-Assist units, oiler, lighting, 3.25 HP

Router motor (Porter cable Only) etc. Please DO NOT plug any of your Vision equipment (except

the vacuum system) into this strip, as it will not function unless the Vision Series 3 controller is

powered on. This is not possible with the “Auxiliary” strip, because it is always OFF unless the

controller is powered on and “AUX ON/OFF” is green.

(Figure 8.3) Tightening the cutter knob in the draw bar.

Zeroing Cutters for Top-Loaded Spindles (see page 15, gure 3.1)

1. Turn the micrometer to zero. This provides a starting point and reference for setting the

depth accurately. It’s important to note that the micrometer should be threaded onto the

spindle housing sufciently to prevent excessive play in the micrometer and nosecone. If there

are too few threads holding the micrometer in place it will move during the engraving process.

The best starting position is 3 or 4 complete revolutions from the top.

CAUTION: When you loosen the setscrew in this step, the cutter may easily fall out of the spindle and can cause cutter tip damage. Use one hand to hold the cutter before loosening.

2. With the appropriate cutter installed in the spindle, loosen the setscrew in the brass cutter

knob with a spline wrench (commonly referred to as the cutter wrench).

3. Gently place a piece of metal against the bottom of the nosecone so as to push the cutter

even with the bottom of the nosecone. Now the cutter should be ush with the nosecone.

Retighten the cutter knob setscrew. Your cutter is now zeroed. Rotating the micrometer clock-

wise will adjust the depth of the cut. Each click of the micrometer = .001”. A full revolution is .025”.

Zeroing Cutters for Top-and-Bottom-Loaded Collet Spindles (see page 15, gure 8.2)

The collet spindle can be used for either top loaded or bottom loaded cutters. To install a top

loaded cutter in the collet spindle, rst set the micrometer to zero. Loosen the knurled draw bar

on the very top of the spindle slightly. Remove the cutter knob from the cutter, and slide the cutter

into the spindle. Place a piece of at material against the bottom of the nosecone and lower the

cutter until it rests against the material. Tighten the draw bar around the cutter, make sure it is tight. Then reattach the cutter knob to the top of the cutter and screw it in counterclockwise until secure. Be careful screwing the cutter knob in, as counterclockwise is the direction to unscrew the draw

bar (see g 8.3). Never use pliers! The cutter depth can be adjusted

by turning the micrometer counter clockwise. Note: If using 2” short cutters, install them from the bottom. Use the draw bar on the very top of the spindle to tightly secure the cutter.

A solid collet, if purchased, can be installed in place of the split collet for burnishing. Install the collet in the bottom of the spindle

and tighten the draw bar rmly. The spindle now acts as a normal

top loaded spindle for ease of operation. The split collet can be reinstalled when required.

Page 29

Chapter 8

Diamond Engraving

To install a diamond drag adapter, remove the retainer ring and nose cone from the bottom of the

spindle and replace with the diamond drag adapter. (See g. 8.4 on the next page) For diamond

drag engraving, the engraving motor is turned off and the cutter “drags” across the material. This

is accomplished with the motor on/off switch in the “off” position. Down pressure against the

material can be reduced or increased as necessary by adjusting the spring pressure adjuster as described in the next section.

Proximity Sensing Device

All current Vision Table Models come standard with a proximity-sensing device.

Below is an explanation and the procedure for operating a Vision engraving machine equipped with a proximity-sensing device.

Advantage of this feature

The advantage of this device is that it eliminates the need to perform a surface setting before zeroing the cutter. It is used when using a nose cone or diamond drag. It cannot be used without a nose cone, in cases such as burnishing or setting multiple pass depths in the software.

Procedure

1. Make sure that the proximity switch is in the “On” position on the controller front panel. Ensure that some travel is allowed to “oat” the spindle on the pressure spring. The pressure spring

adjuster must be backed off.

2. Zero the cutter in the spindle and dial in the desired depth on the nose cone micrometer.

3. Send the job down to the controller via the computer.

4. Press the “Start” button on the controller front panel to begin engraving.

IMPORTANT NOTES:

“Nose-riding” - WITH proximity sensor

Engraving with the proximity sensor can only be performed with a nose cone attached, or when diamond drag engraving.

“Non-nose-riding” - WITHOUT proximity sensor

When setting a depth in the computer engraving program, the proximity sensor should be in the

“Off” position on the controller front panel. Also, make sure that there is no “oat” on the spindle

by locking the pressure spring adjuster all the way down. Locking is especially important when engraving into hard surfacesor materials like brass and stainless steel.

Chapter 9: Table Maintenance

The Vacuum Chip Removal System

The optional vacuum chip removal system is designed to simplify the engraving process and minimize wear and tear on the engraver. The vacuum chip removal system uses a vacuum nose cone to remove chips created during the engraving process before they have the chance to create

problems. The quiet pump, coupled with the microne-layered lters assures that your unwanted chips are whisked away effortlessly. The vacuum pump canister uses replaceable lters that can also be reused, to assure maximum efciency and cost-effectiveness.

Vision strives for the highest quality in their manufacturing process to provide you with the most cost effective, reliable engraving machine in use today. Please remember that proper maintenance and care is necessary to achieve maximum product life expectancy.

The engraving environment generates small plastic and metal chips as well as other particles during operation. As with any machinery, your engraving system should be kept as clean as

possible to minimize wear and tear, and to improve nal quality of the engraved product.

REMOVING CHIPS

A portable vacuum is suggested for chip removal, but applying direct suction to the spindle area

is not recommended. Note that this cleaning can be minimized and greatly simplied through the

use of the optional vacuum chip removal system. The vacuum chip removal system removes chips and dust created by engraving. This system can also extend the life of other components in the system, as prompt removal of chips reduces contamination and overheating in the spindle area. The vacuum chip removal system also keeps the nose cone from skipping over letters due to chips on the engraving surface.

REPAIRS, REPLACEMENTS, AND ADJUSTMENTS

How to replace a belt

A belt is used to drive the spindle engraving system. It runs between a drive pulley

and the spindle pulley (see Fig.9.1). If it needs replacement, remove the old belt

by rolling it to the top of the spindle pulley, and give it a slight stretching motion to snap it off the end. Once loose, it can easily be removed from the machine. Now position the new belt around the drive pulley, then stretch it to snap over the top of the pulley.

NOTE: Be sure to puchase the specied replacement belt from Vision

Engraving Systems. Having the correct belt size is extremely important to the functionality of the motor. NEVER STRETCH THE BELT!

(Figure 9.1)

Page 32

Chapter 9

The motor brushes on the engraving motor should be inspected regularly, and replaced when worn. Two brush assemblies are included with the accessories package. (One for each side of the motor.)

Inspect the brushes for possible replacement at least every six months. (see gure 9.2)

The engraving motor is the large, black motor (where applicable) on the top of the carriage assembly. Unplug the speed controller to remove power to the motor. Perform the inspection (one brush at a time) to simplify reinstallation. At the top of the motor are two round extensions looking

similar to ears. Using a at-blade screwdriver, carefully remove the small threaded brush cap

from the center of one of the “ears”. If you screw it in the wrong direction, the cap will descend into the ear instead of rise out. Remove the metal U-shaped bracket connected to the spring and carbon brush. It will be found underneath the brush cap. Observe how you remove the brush, so that reinstallation will be easier. Examine the brush for wear by comparing it to a new brush, or by measuring the length of the carbon brush. If the carbon brush is less than a quarter of an inch long, replace the entire assembly. Do not attempt to separate the carbon brush from the wire,

spring and bracket. Reinstall the old or new bracket/spring/brush assembly followed by the

plastic brush cap. Repeat the inspection procedure for the brush on the other side of the motor.

NOTE: If either brush needs to be replaced, replace both brushes as a set.

LUBRICATION

Lubricating the X-Axis, Y-Axis and Z-Axis lead screws (ALL MODELS)

A light lubrication of the X and Y and Z lead screws should

be performed after every month of usage (see schedule on next page). Use silicone lubricant spray only. Spray a light coating along the entire lead screw.

Note: A nozzle extender attached to the aerosol spray can help facilitate this procedure and may eliminate the need to remove the metal covers.

DO NOT use any lubricant other than silicone, as it may become sticky and cause a buildup that will cause mechanical failure.

What NOT to lubricate

Many of the bearings and assemblies in your engraving machine are sealed and/or coated using special low-

friction methods and should not be lubricated.

DO NOT attempt to lubricate the spindle or the spindle bearings. If you suspect lubrication problems, call Vision for instructions, as further lubrication may harm the machine.

DO NOT lubricate the X or Y stepper motors.

Spindle Lubrication (for Series 3 Vision Tables only)

The spindle assembly in the Series 3 Vision Tables requires a monthly lubrication of the housing (as shown in Fig.9.5). Simply push the spindle up until there is a 1/3” gap between the

spindle block and the “lip” of the housing. Lubricate with

2 to 3 drops of 3 in 1 oil.

DO NOT OVER LUBRICATE! Never lubricate the spindle bearings! This wil cause the spindle to stick.

MAINTENANCE SCHEDULE

The following is a suggested maintenance schedule. Remember that in conditions of prolonged use, unusual environments, or unusual applications, maintenance items may need to be performed more frequently than suggested in this schedule.

Spindle Housing “Lip”

Riser Block Extensions

The optional riser block kit allows you to raise the entire gantry assembly quickly and simply. Each end of the gantry assembly is supported by two tower blocks stacked on top of each other. Riser blocks are installed between the two tower blocks, and add height to the gantry.

Riser Block Installation (See Fig 9.6)

Determine the extra height required, and select riser blocks of appropriate height. One end of the gantry has long threaded rods topped by washers and nuts. Loosen the nuts on the threaded rods. On the other end of the gantry, loosen the bolts. Raise the gantry for clearance, and slide a riser in between the two tower blocks on each end of the gantry. For higher extensions use the longer bolts and additional riser extensions as needed. Always add the same height to each end of

the gantry. When nished installing the riser blocks, be sure to retighten all bolts and

threaded rods.

Spindle Options

Increase your prots and engraving quality with the split collet spindle (see g 9.7). Designed to be

extremely accurate and durable, the collet spindle is simple to use. This collet retracts around the

cutter gripping it at the bottom, while rmly holding on the top. By holding the cutter in two places

the cutter is virtually vibration-free and nearly eliminates play and runout. The split collet spindle can engrave with excellent clarity and resolution while averaging a longer product life than any other spindle. The collet spindle accepts both top loaded and bottom loaded cutters, including 2” short shank cutters such as drill bits, router bits, dremel tools etc. Should you ever want your split collet spindle to act like a standard spindle, simply install our solid collet in the spindle (available separately).

Diamond Drag Adapters

Using your plastic cutters to engrave metal can seriously damage them. There is a better option; Vision offers high-quality diamond drag adapters. Don’t burn out your bearings on a job that can be done just as easily as cutting plastic. The diamond drag adapter engraves virtually all-metallic surfaces, at high resolution and high speed. The results achieved with a diamond drag adapter can be even more amazing when used with double- and triple-line fonts.

ENGRAVING PROBLEMS

Problem: Engraving on the plate is “slanted”. Possible solutions:

1. Check material for squareness. Maybe your shear does not cut squarely.

2. Check to see if the material on the table is indeed at a true home and is square to your scale bars or stops.

3. If your table is equipped with scale bars insure that they are secure and ush to your T-Slot

table. Hint: Always inspect your job before removing your plate from the system. You may be able to salvage it by re-engraving the job, or at a minimum, you may be able to analyze the problem and prevent repeating it. Perhaps the plate moved during engraving. Removing it without inspection would prevent you from detecting this problem.

Problem: You are using a nosecone, but your engraving is “shallow” across the top or left margin of your plate. It engraves properly when the spindle is away from the edge.

Possible solutions:

1. Your nosecone is riding on the scale bars or side stops. Loosen and lower the scale bars so that they are below the level of your material surface. Retighten the thumbscrews.

2. Check to see if your material is riding on the scale bars or side stops. It’s not hard to miss during set-up especially if the plate is thin material.

Problem: You are using a nosecone and your engraving is uneven. Possible solutions:

1. Your spindle is not “zeroed” to your material. Follow the steps in “Chapter 3” to zero your

spindle.

2. You are not using enough oat and need to adjust the down stroke until your nosecone touches

the material with some pressure.

3. You may be engraving too fast for the type of material you are cutting. Check the manufacturer’s

recommendation. The cutter may be bouncing on the surface. Some hard materials may exhibit this problem.

4. You may have a defective or broken cutter. Replace it.

5. Your material may be defective.

6. Your vac chip removal system is plugged and engraving chips are caught between the nosecone and the material.

7. The nosecone or vac nose is loose.

Problem: “Shadowing” occurs while engraving certain materials. Possible solutions:

1. Leave the protective lm on the engraving material during engraving.

2. Use a plastic nosecone instead of a metal one.

3. The nosecone may be damaged. Inspect for burrs or roughness. Try using an emory cloth to polish the nose.

4. Back off on the spring pressure. Excessive down pressure will leave a rub mark on almost any

plastic material.

Chapter 10

Page 38

Problem: You are not using a nosecone and you have uneven engraving. Possible solutions:

1. Switch to a nose-riding method.

2. Use a different method of holding the material. If you use double sided tape, it may be thick

enough to change your surface atness by a few thousandths.

3. Parcel the job if possible so that you can have more direct control over the depth of each specic area. This may be effective if you have uneven material or a large engraving bed.

4. Table tolerances may not be able to maintain the accuracy level you want.

5. Table may not be on a level surface.

Hint: While it’s true that you can do non-nose riding engraving, it’s not easy to hold any controlled accuracy on the depth. This takes at material, a very at bed and some degree of skill and condence. It also takes an application where some amount of uneven engraving may be tolerated.

Problem: I’m getting “tails” or “swirls” in the corners of my engraving. Possible solutions:

1. Your cutter speed is too fast relative to your x-y speed. Slow your spindle speed down or increase your table speed.

2. Your cutter is worn or damaged. Replace.

3. Turn down the dwell speed.

Problem: I’m getting “fuzz”, “fur” or can see lines in the bottom of my cut showing each cutter path. I can even see steps in the bottom of my cut.

Possible solutions:

1. This problem is tough. Sometimes caused by dull cutters, the wrong cutter, or not enough overlap for each cut. Try changing cutter size slightly. You may get better clean up.

2. Try taking a second pass cut at .001-.002 deeper. This may clean up the roughness.

3. Resharpen the cutter. There are various cutter angles that can cause these kinds of problems.

There is a relief angle that if too great can cause noticeable ridges in the bottom of the cut.

4. Ensure that the spindle is square in the mount or block. An unsquare spindle means an unsquare cutter to the material surface.

5. Turn spindle speed up.

Problem: Poor letter quality. Possible solutions:

1. You may be engraving too fast. Engraving quality improves with the right engraving and spindle speeds.

2. If you are diamond drag engraving, you have too much down pressure or you are engraving too deep. Also, check the grain of the material; it should be left to right.

3. You may have a worn or dull cutter.

4. Your material is not securely fastened to the table.

Probelm: Ragged Type. Possible solutions:

1. If the quality of cut is ragged or exhibits steps, you may have play in the cutter.

Chapter 10

Page 39

Chapter 10

This could be in the gap between the cutter and the spindle shaft. Maybe the shaft is worn or

the spindle bearings need to be replaced. Once a shaft starts to wear and a cutter is loose, the problem can worsen quickly.

2. The spindle is loose in the housing or block.

3. The carriage is loose or has excessive play, check the z-axis bearings or slide.

4. Lubricate lead screws with recommended lubricant.

Problem: My baseline is off. Possible solutions:

1. You’re not at the mechanical or software home. Maybe the table or carriage was bumped during set-up. Maybe the previous job was cut short and the system did not return back to its mechanical home or limit switches. Move the table, bridge or carriage physically to home or send it

home via the software.

2. Check your software layout for keystroke errors.

Problem: While burnishing aluminum I have voids or non-engraved areas. Possible solutions:

1. Try re-engraving the same plate again. Some of the anodized aluminum plates have very hard surfaces and two passes are required.

2. Switch to a diamond burnisher. The more common carbide tools may have difculty getting

through the tough surface and are more easily worn down, thus sometimes skipping across the surface.

3. Increase the pressure of the z-axis or burnishing adaptor.

4. Try other materials. Same reasons as above. Some materials, from some vendors, are just plain

tough.

Hints:

Always try to solve the problems yourself before seeking help. A little patience goes a long way.

Never work on any problem that gets you so frustrated that you become irritated at the machine, the service technician, or the salesman. It’s only a machine, don’t let it get the best of you. Contact your dealer.

MECHANICAL PROBLEMS

Problem: No X, Y or Z-Axis movement. Possible solutions:

1. Check that the controller power is on.

2. Check that the drives are turned on.

3. Check the table cable for a solid connection. It may be helpful to remove the cable,

reconnect and tighten the hold down screws to ensure a good connection.

4. Ensure that the job has been transferred to the controller (Green start light is ON).

5. Ensure that the emergency STOP button is not depressed, then turn the drives on.

Page 40

Problem: System has no movement in any one axis. Possible solutions:

1. Try to jog the problem axis using the X/Y/Z jog keys on the control unit. If OK, retry the job.

2. Check the table cable for a solid connection.

3. Call service technician for further instructions.

Problem: Unusually loud noises during the engraving process. Possible solutions:

1. Isolate the cause of the unusual noise by: a. Remove the cutter. b. Turn the engraving motor to OFF.

c. Run the engraving job, or X/Y jog the system.

If the noise persists, it may be conned to the X, Y or Z-axis. Check for proper lubrication of lead screws. Follow lubrication instructions in chapter 4.

If the noise goes away and to further isolate the cause, do the following: a. Remove the motor belt. b. Run the engraving motor without starting a job. Loose motor belts may cause some noises, so removal will narrow down the problem. If the noise is present with the spindle motor on, check the motor brushes.

If there is no unusual noise when running the spindle motor with no belt attached, do the following: a. Attach the motor belt.

b. Run the spindle motor and vary the RPM by changing the control unit potentiometer.

Noise levels may vary. If the noise persists, check the spindle for overheating. Excessive overheating of the outside housing of the spindle is a sign of defective bearings. The noise may be caused by the bearings.

Problem: Spindle is hot. Possible solutions:

1. Ensure that the nose cone area is free of debris. Check the vacuum system (if used) for clogging.

2. Inspect the spindle for other obstructions that may prevent proper rotation.

3. Bearings may need to be replaced.

Problem: Spindle motor will not come on. Possible solutions:

1. Check the auto/on/off switch to ensure the proper operational mode.

2. Check motor brushes.

Problem: Motor belt will not stay on pulley. Possible solutions:

1. Motor belt is probably worn and needs to be replaced.
