Use of LPKF BoardMaster

ProtoMat C30/C30-S 19

5.0 Use of LPKF BoardMaster

The data required to drive the plotters is generated by postprocessing with LPKF

CircuitCAM

and is stored in a binary LPKF file (LMD format).

BoardMaster

now reads these files, decodes the plotter commands and

modifies them for the particular machine being driven.

This is necessary as although different machines may perform similar operations, they nevertheless use different command sets.

The LPKF

ProtoMat C30 (C30/S)

circuit-board plotter is HP-GL compatible, ie the driver generates data in HP-GL format plus some special commands.

Modifications such as enlargement, rotation and duplication etc can be made in LPKF

BordMaster

.

All LPKF circuit-board plotters are controlled through an asynchronous interface (RS232C).

In the case of the LPKF

ProtoMat C30 (C30/S)

, this is set at

9600 Baud, 1 stop bit, 8 data bits, no parity, hardware handshake and FIFO off

in the Windows control panel.

Setup

20 ProtoMat C30/C30-S

6.0 Setup

Caution! You must ensure that the voltage set on the machine corresponds with the mains line voltage before switching on. If not, see the section headed Setting the device voltage, electrical fuses. Remove all objects from the plotter and its traverse range before switching on. Pilot pins must not be projecting from the base material.

Danger! Never reach into the machine while it is being switched on. Never move the plotter head manually. Doing so could damage the electronics.

6.1 Switch-on sequence

It is useful, but not essential, to keep to the following switch-on sequence:

1.

Computer

2.

LPKF

ProtoMat C30 (C30/S)

3.

Start up the

BoardMaster

program

If, for whatever reason, it should be necessary to switch the machine off and back on, you must switch briefly to the

BoardMaster MACHINE

SETTINGS...

dialog box and quit this with OK. This will send the necessary initialization parameters, such as speed ranges, dwell times, positions and so on to the machine once again.

6.2 After switching on

The equipment moves to the x and y limit switches when the machine is switched on. The system first halts in the tool change position. It now waits for commands from

BoardMaster

. Check the following if the

equipment does not move when it is switched on:

1.

Is the POWER LED lit (only lights after successful initialization)?

2.

Are all cables correctly inserted?

3.

You may need to check the power supply fuses.

Functional test with LPKF BoardMaster

ProtoMat C30/C30-S 21

7.0 Functional test with LPKF

BoardMaster

Danger! Make sure that no other persons are working on the machine when the first functional test is taking place.

First check that the parameters for the serial port:

• 9600 baud

• 8 data bits

• 1 stop bit

• no parity bit

• hardware handshake

• FIFO off.

Also check that the correct interface has been selected in

BoardMaster

under

CONFIGURATION, INTERFACE...

. Consult the

BoardMaster

Manual if you require assistance. The remainder of the procedure is carried out using

BoardMaster

:

fig. 6:

1.

Move the head manually using the cursor keys on the

BoardMaster

toolbar (3).

2.

Switch on the motor. (1)

(The motor runs at low speed during the warm-up phase)

3.

Wait for the warm-up phase to complete.

4.

Lower/raise the head (2).

5.

Switch off the motor (1).

6.

Check the interface configuration, the connecting cable and the PC

interface if the equipment does not move.

Note: The motor cannot be switched off when the machine is in the tool change position.

7.1 HOME position and registration hole system

The HOME position must be on the machine's axis of symmetry (registration hole system) for double-sided base. Double-sided base material are rotated about this axis of symmetry.

Inaccuracies in the HOME position result in misalignment when doublesided base are rotated during the machining process.

The HOME position is contained on the configuration diskette supplied as standard. With the

BoardMaster

program and configuration diskette correctly installed, the HOME position corresponds to the setting for the x/y coordinates as measured during the acceptance test.

Note: The registration hole system can only be guaranteed to be parallel for the current position of the registration hole strips. The front registration hole slide must be pushed against the pin in the reference groove (reference point). An additional hole must be drilled for each format in the rear registration hole strip if base material of different sizes is used. To do this, move from the HOME position towards the rear registration hole strip. Now move the rear registration hole strip to the required position. An additional hole is drilled in the slide using a 2.95 mm drill. The position of the slide for the various holes should recorded or marked on the circuit-board plotter. This guarantees parallelism for different formats.

You will need to perform a test run on the machine to check the coordinates of the Home position on new machines and after transporting the system.

The individual steps are described in the next section,

"Checking and

correcting the HOME position".

No further action is required if the preset coordinates are correct. If this is not the case, the corrected coordinates will have to be entered in

BoardMaster

. See the section entitled

"Programming the HOME

position in

BoardMaster

".

7.2 Checking and correcting the HOME position

The test file Null-Pkt.LMD is supplied with installation program to simplify the procedure for checking the HOME position.

This program drills a hole on one side of the board and then rotates the board before milling a circle in the same place. This allows you to perform a visual check on the position of the Home point in both axes.

Caution! Bevore beginning you must read the chapters " Operating the working depth limiter" and "Changing a tool (C30)" as well as "Changing a tool (C30/S).

7.4 Creating a new registration hole system

The registration holes in the red registration hole strips grow with use over time will no longer be as precise as they originally were. New holes must be drilled in the strips if this is the case. The registration hole strips must be replaced if there are too many holes them after some time.

fig. 15: Front strip of the registration

hole system

A new registration hole system is created as follows:

› First press the two registration hole strips into the machine groove,

with the front registration hole strip pushed against the reference pin at the front of the groove. The distance between the two registration hole strips should be approximately the size of the base material in the X axis.

› Select the tool in

BoardMaster

: "Spiral Drill Ref 2.95 mm"

› Fit the 2.95 mm diameter drill so that the distance between the base

plate and the tip of the drill is approximately 0.5 mm. This is the

only

time a tool is not inserted into the collet as far as it

will go.

› Adjust the working depth limiter to the very top using the knurled

screw so that the drill stroke is lengthened.

› Use

GO TO, HOME

from the

BoardMaster

menu to move the plotter head to the Home position and then use the arrow buttons to move the head to approximately the centre of the front registration hole strip.

› Switch on the motor by clicking and (raise/lower head) to

drill a hole approximately 4 mm deep. Do not move the position of the plotter head in the Y axis again.

› Use the arrow buttons in

BoardMaster

to move the plotter head approximately 25 mm in the positive X direction and define this position as the new Home position: Open the

dialog box in

BoardMaster

via

and click on the

SET HOME

button. (see also the section entitled Programming the

HOME position in LPKF

BoardMaster

)

› Move along the X axis to the second, rear registration hole strip and

drill a hole approximately 4 mm deep there too. It is imperative that you do not move in the Y direction. Select a distance suitable for working with a standard base material. For example, an A4 board is 297 mm, so a registration hole 5 mm from the edge of board gives a distance between the holes of 287 mm. Simple method:

› Enter the value 287 in the

STEP WIDTH

box in

BoardMaster

and

then press the arrow button.

The plotter head moves in one 287 mm step to the new position.

› Now remove the drilling tool by selecting a different tool in

BoardMaster

.

› Move the plotter head to the side. Insert two alignment pins in the

holes now made in the registration hole strip. Please check that the pins are positioned securely as any play has a detrimental effect on alignment accuracy.

› Mark old holes with a felt pen so they cannot be confused with the

new ones.

› Position the previously drilled base material and drilling backing over

the alignment pins. The format of the base material should be selected so that the registration hole strip does not need to be moved more than 10 mm. Moving the registration hole strip more than 10 mm reduces the accuracy of the registration hole system.

› Now secure the base material in this position with adhesive tape

(we recommend Tesakrepp 5250) on all four sides.

Danger! Please note that very sharp tools are involved and that they may become hot. Always work with the vacuum system switched on to avoid injury from swarf..

Note: You should select a distance between the registration holes which allows you to work with standard base material. A DIN A4 size board has a side length of 297 mm so holes 5 mm from the edge give a distance between the holes of 287 mm.

9.2 Materials used for machining

In general, all base materials supplied by LPKF can be used for machining. You are free to machine all other materials at your own risk. Please follow the manufacturers' instructions.

However, phenol resins of lesser quality, such as FR 2, can adversely affect the milling quality. Glass fibre reinforced epoxy material (FR 4 or G 10) can present a health hazard due to the milling dust produced (allergies, risk of cancer). Tool service life is also substantially reduced.

Caution! Never work without the extractor running.

We recommend epoxy material without glass fibre (FR 3). A total thickness of 1.5 mm with a 35 µm copper coating is normally used.

Yielding milling is of the highest quality and a high tool service life, FR 4 has no known drawbacks other than a slightly reduced mechanical load capacity (breakage). This should not be a significant drawback for prototype boards unless particularly heavy components are to be mounted.

Even finer milling channels can be engraved on 17 µm material at a higher packing density. A 5 - 17 µm copper thickness is used for galvanically through-hole plated, double-sided base to prevent an excessively thick copper layer building up following galvanic copperplating.

Compromises must be taken for 70 µm material when setting the milling depth in that a deeper milling depth results in wider milling passes of 0.3 to 0.6 mm. Special base materials with a thicker copper layer of up to 300 µm can no longer be machined with the LPKF universal milling cutter. Contour milling cutters or special tools are needed for these materials. In these cases, we would ask that you consult us and send sample material so that we can carry out any tests which may be necessary.

A drilling backing is essential for all machining processes on base material. This allows holes to be drilled through the board without damaging the machine. The drilling backing can be made simply of bakelized paper and should be 2 mm thick.

Material supplied by LPKF and suitable for machining:

FR3 material: engraving, drilling, milling

FR4 material : engraving, drilling, milling

Engraving film: engraving

Other materials upon request.

Tools, material and accessories

36 ProtoMat C30/C30-S

Danger! Do not allow to the material overheat - lethal gases may be produced.Carcinogenic dusts may be produced when working with materials containing glass fibres. You should therefore always work with the vacuum system switched on. Carcinogenic dusts or hazardous gases may be produced when working with unknown materials. Ask your supplier or the manufacturer before you begin machining.

Procedures for milling and drilling

ProtoMat C30/C30-S 37

10.0 Procedures for milling and drilling

10.1 Securing the board

Make 3,0 mm or 3,05 mm diameter congruent registration holes in the base material and drilling backing in the X axis. This can also be done with any bench drill. Note that the diameter decreases during galvanic through-hole plating.

Note: The drilling backing should be drilled to a larger diameter, such as 5 mm to allow for inaccuracies in the registration holes.

› Move the plotter head to the Pause position.

› Insert alignment pins in the front and rear registration hole strips.

It is essential that you make sure the front registration hole strip in the machine groove is pushed against the reference pin at the front.

› Position the drilled base material and drilling backing over the

alignment pins. The format of the base material should be selected so that the registration hole strip does not need to be moved more than 10 mm. Moving the registration hole strip more than 10 mm reduces the accuracy of the registration hole system.

› Now additionally secure the base material in this position on all four

sides with adhesive tape (we recommend Tesakrepp 5250). This prevent the corners of the board bending up.

fig. 20: Securing the board

The alignment pins hold the board in position. They also act as a reference when double-sided base are rotated.

This is particularly important for contour milling.

It is important that no adhesive tape, drilling or milling swarf is left between the individual layers to ensure that the base material lies absolutely flat. Small particles under the base material have an adverse affect on the uniformity of the milling depth.

Caution! Switch on the vacuum system. Bear in mind that the vacuum filter might need be changed.

10.2 Operating the working depth limiter

Danger! Keep your fingers clear of the machine's traverse range during operation.

It is particularly important that you keep the milling depth constant when milling isolation channels in base materials which tend to be slightly curved. LPKF

ProtoMat C30 (C30/S)

achieves this using the mechanical

working depth limiter.

This has following benefits:

• The depth limiter rides on the surface of the material. The working depth limitercan follow slightly warped boards.

• The material is held down within certain limits by the working depth limiter. The head is lowered by a solenoid actuator and raised by a spring.

fig. 21: The LPKF ProtoMat C30

(C30/S) working depth limiter

The milling depth is set by adjusting the knurled nut (2) on the working depth limiter. Turning the wheel clockwise increases the milling depth and also the milling width in the case of LPKF universal milling cutters due to their conical shape. Turning the wheel anti-clockwise reduces the milling depth. The milling depth is altered by approximately 4 µm for each click of the wheel. Turning the wheel anti-clockwise is easier than turning it clockwise, particularly when the head is lowered.

10.3 Changing a tool (C30)

› Remove the tool fixing screw (see picture working depth limiter)

› Pull out a possibly available tool with the help of a tweezers from the

tool housing.

› Introduce the new tool up to the plot in the tool housing with a

tweezers.

› Move and fix the fixing screw.

10.4 Changing a tool (C30/S)

The plotter spindle collet on the

ProtoMat C30 (C30/S)

is operated by a lever which simultaneously disengages the DC motor via a clutch as a spring packet opens the collet.

Caution! There must be a tool in the plotter spindle collet whenever the machine is switched on. It is imperative that the collet is closed. (The collet is closed when the lever is in the “up” position). Operating the lever when the motor is running could damage the coupling between the motor and the collet. Do not switch on the motor by opened tool clamp or without tool!

fig. 22: Operating the plotter spindle

collet

Position A: Lever in the normal position. The collet is closed.

The motor is connected to the spindle by a clutch.

Position B: The lever must be pushed down to open the collet.

The clutch disengages the motor and a spring pack opens the collet.

Position C: After the lever is pushed down, the open collet is locked open by moving the lever to the right. It is now a simple matter to change the tool using the tweezers supplied.

10.5 Drilling

fig. 23: Twist drill

Caution! Make sure that the board is secured in position before drilling. Switch on the vacuum system.

The boards must be drilled with drills designed specifically for boards. It is important that the head always lowers at a constant speed. This is ensured by a damper built into the plotter head. Lowering the head too quickly may result in burring, particularly with holes of small diameter. We therefore recommend that you punch holes with a small diameter before drilling. The

MARKINGDRILLS

phase in

BoardMaster

is intended for this purpose and uses a special universal

milling cutter, the

0.2 MM UNIVERSAL MARKING CUTTER

.

Only one board can be drilled at a time. It is not possible to stack boards one on top of the other. A drill cover plate is not required. All drills are 38 mm long. See the section entitled “Practical tips” for further instructions.

10.6 Isolation milling

fig. 24: LPKF Universal (1) and

microcutters (2)

Caution! Make sure that the board is positioned securely before milling. Switch on the vacuum system.

Ensure that the (36 mm long)

LPKF universal milling cutters

being used

are

sufficiently sharp

before you start milling. The milling width is

preset in

CircuitCAM

by selecting the isolation track width and the

appropriate tool. The preferred milling width is between 0.2 and 0.4 mm.

Procedures for milling and drilling

ProtoMat C30/C30-S 41

As a rule, the milling depth must be set as wide (deep) as possible. The tool wears more quickly if only the extreme milling cutter tip (<0.2 mm isolation) is used than with deeper milling.The LPKF micromilling cutters can be used to create even finer isolation channels but their service life will be only approximately 20% of that of the LPKF universal milling cutters mentioned above.

Caution! Do not confuse micromilling cutters and universal milling cutters. It is only possible to distinguish the two under a microscope.

fig. 25: Milling passes using the

LPKF universal, and micro cutters

See the section entitled “Practical tips” for more information.

The board must be cleaned after machining. This can be done either in a brush machine or, alternatively, with a manual board cleaner (LPKF accessories).

In either case, the board must be rinsed thoroughly with water to remove any copper dust produced by brushing. After rinsing, the board must be dried thoroughly (hair drier) and then protected against oxidation by a soldering varnish.

10.7 Contour milling in base material

fig. 26: Contour milling cutters

The traverse speed has to be reduced for contour milling. This may differ from material to material. Use only contour milling cutters (38 mm long) designed specifically for this purpose: 1 or 2 mm diameter if possible.

The 1 mm contour milling cutter should only be used for internal cut-outs (smaller internal radius). It breaks relatively easily so set the feed rate to the minimum setting.

The 2 mm contour milling cutter is far more robust and is to be recommended for milling external contours.

Procedures for milling and drilling

42 ProtoMat C30/C30-S

Danger! All speeds and feed rates prescribed in

BoardMaster

are for FR4 material. You should begin at a lower feed rate when working with other materials. Please note that some materials, including FR4, may produce carcinogenic dusts (from glass fibres). You should therefore always work with the vacuum system switched on. Always use a microfilter. Some materials (such as Teflon) may produce lethal gases during cutting.

10.8 Milling wide isolation channels and rubouts

fig. 27: Double-chamfered cutter

Wide isolation channels and rubout areas (the removal of areas of residual copper) can be created using 36 mm long double-chamfered cutters.

Various diameters (0.8 mm, 1 mm, 2 mm, 3 mm) are available depending on the size of the area of copper residue to be removed.

The milling depth must be set such that the copper is removed with minimal burring. The 3 mm double-chamfered cutter is particularly well suited to milling very wide isolation channels (VDE regulations).

10.9 Front plate engraving

fig. 28: Top: Double-chamfered

cutter. Bottom: LPKF universal milling cutter

Set the traverse speed as appropriate for the engraving depth and the material when engraving. Use an LPKF universal milling cutter or LPKF double chamfered cutter.

Danger! Switch on the vacuum system, even when engraving.

10.10 Milling solder-stop sheets

Create the pads in solder-stop sheets using a Unimill 100 Micromill with a tool diameter of 0.15 mm.

The speed should be set to 20,000 rpm and the advance to 5 mm/s.

Note: Set the milling depth using an edge area of the solder-stop sheet which is not used. Use the arrow buttons in BoardMaster to mill a 2 x 2 mm square with the motor switched on and check the depth.

› Once the milling depth has been set, start the milling procedure

using the file prepared by

CircuitCAM

.

› At the end of the milling procedure, check that all the pads have

been cut out.

› Start the milling procedure a second time if this is not the case.

10.11 Milling layout films

fig. 29: LPKF HF milling cutter

Layout filmscan be machined with LPKF HF milling cutters.

› Secure the film base (plexiglas or glass sheet) onto the machine

bench with Tesa tape.

› Lay the film material on the base with the coated (matte) side facing

› Now flatten the film material out firmly flat and on the film support,

expelling any air completely.

› Now stick down the film on all four sides with a non-stretching

Procedures for milling and drilling

44 ProtoMat C30/C30-S

› The film milling program may now be started.

Film material comes in DIN A3 and A4 formats (special sizes available upon request).

Note: The film coating is easily scratched and is water soluble, so do not let it come into contact with water.

The film can be recopied with a staining device upon request. See the section entitled "Practical tips" for more information.

10.11.1 Staining milled films

Duroscal black stain is available for milled negative films which can then be used to make positives. The fully milled engraving film is stained with Duroscal stain by pouring the liquid onto a SAFIR pad and spreading it evenly over the whole film. Excess stain must be wiped off with cellulose wadding.

The stained film must be held against the light to check it and to find poorly covered areas so that they can be re-stained. Now remove the coating immediately. The stain must not be allowed to dry.

Caution! Follow the instructions on the stain container. The stain must not get onto the back of the film as it cannot be removed. The stain is also very difficult to remove from other surfaces (fabrics, skin). Wear an overall and rubber gloves.

10.11.2 Removing the coating

Treat only one film per container when removing coatings to prevent any damage to the second film resulting from contact between its reverse and a surface which is wet from the stain.

Caution! Follow the safety instructions on the quick-acting coating remover container.

Procedures for milling and drilling

ProtoMat C30/C30-S 45

There are two methods of removing the coating:

Quick coating removal.

Pour the quick-acting coating remover onto the film and immediately wipe the dissolved protective coating with cellulose applying light pressure. Now dry the film with cellulose wadding, blotting paper or a cloth.

Removal with water.

This method involves placing the film in a bowl of hand-hot water (to which a small amount of washing-up liquid has been added). The protective layer dissolves after about 30 minutes. Any remaining coating must be removed with a fine hand brush. This method is more economical and kinder to the environment than the quick-acting method of removal. The film can be left in the water bath as long as you want.

11.1 Cleaning the board

The finished board must be thoroughly cleaned before components are mounted. This can be done manually or in a board brushing machine.

Place the board on a flat surface to clean it by hand. Brush the board with a wet board cleaner (such as the LPKF PAD board cleaner) in the preferred direction of the conductor paths. The point of brushing is, firstly, to remove the layer of oxidation, and, secondly, to remove any burrs resulting from the use of a blunt tool.

After brushing, the board must be clean of any metal particles. From now on, the board should only be held by its edges or with gloves.

It is best to rinse off the board under running hot water to remove any brushings from the isolation channels.Now dry the board with an air drier. After drying the board coat it on both sides with soldering varnish.

Caution! Never use compressed air to blow out the channels as any oil particles in the air introduced by a faulty oil separator can cause problems later in the manufacturing process.

machine bed is truly clean

.

• Adhesive tape residue and such like can have a significant adverse affect on the milling depth.

• Millings between the machine bed, drilling backing and board reduce precision.

• Severely

distorted materials

bend such that the flexure is visible underneath; in this case, secure the edges well with adhesive tape. Ather important point for precise milling depth is that millings and drilling chips are

removed by suction

.

• Hooks can occur between the milling tracks if the incorrect milling suence is followed, in particular with circles. If a circle is to be milled anti-clockwise with a tool which rotates clockwise,

fine hooks

can occur between the copper areas if the milling tracks overlap. The reason for this is that the cutting speed on the outer edges is reduced. The solution is to select the correct direction of milling. In addition, you can select the

Remove spikes

option on the

Strategy

tab in

CircuitCAM

when you set up the isolation job.

•

Milling burrs

can be caused by blunt tools or incorrect traverse

speeds.

• Deeper settings may be the answer if the structure to be milled allows. Otherwise, change the tool.

•

Burrs

arising during contour milling or

cut edges which are not

clean

are caused either by a blunt tool or an incorrect feed rate.

• With some materials, the

colour of the milling pass

gives some indication of the condition of the tool. Dark isolation tracks on epoxy materials indicate that the tool is sharp, while lighter tracks indicate a blunt tool.

•

Drilling burrs

are caused either because the tool is blunt or the head is being lowered too quickly. In the first case, change the tool. In the second case, reduce the tool height over the material.

•

Drill deflection

occurs where thin tools which are no longer absolutely sharp are used. However, surface structure of the material may also be a factor. Drill deflection cannot be avoided even with a sharp tool if, for example, the glass fibre structure of FR4 materials penetrates the copper. Drill deflection is very slight for materials with additional, removable copper film (FR4 material with 18 µm or 9 µm copper coating).

Practical tips

ProtoMat C30/C30-S 49

Note: We recommend that you punch-mark small diameter holes before drilling. The MarkingDrills phase in BoardMaster is intended for this purpose and uses a special universal milling cutter, the "0.2 mm universal marking cutter".

•

Vitrification of the drilled hole

occurs where the drill remains in the hole too long after the hole has been made. These holes then cause problems for through-hole plating. Ruce the drilling times as appropriate.

•

Drills may break

where the drilling backing has already been used a number of times. The drilling backing should be changed for each new board. The drill may break if it comes into contact with the edge of an existing hole in the base. Broken tools must be removed from the board and the drilling backing. Very thin drills may also break if the tool is too high above the material.

•

Milling passes

created during film milling

will be uneven

if there is air still trapped under the film. The film may buckle after a while if

elastic adhesive tape

is used to secure the film. It is particularly important that the milling backing is flat (LPKF engraving film backing).

•

Burrs

will be produced when milling film if either the tool is blunt

or milling is too deep.

•

Uniform misalignment

between the solder and component sides occurs where the HOME position has not been programmed accurately.

•

Increasing misalignment in the X axis

between the solder and component sides occurs where the registration hole system is no longer parallel to the X axis. A new registration hole system will have to be drilled.

› After cleaning, the working depth limiter is reassembled in reverse

order and the motor is reinserted in the retaining block.

› Always check that the insertion depth of the spindle is correct before

starting up.

The distance between the drill tip and machine base plate must be 0.5 mm when the head is lowered. The machine may not be able to drill through the board if the distance is too great. A larger diameter should be used for the drill because a smaller drill can easily break as it is being adjusted.

› Finally tighten the screws

13.10 The Command set

13.10.1 Command structure

The SMCU (Signal Processor Control Unit) control unit in the machine interprets the HP-GL commands described below and converts them into defined actions.

The

machine has a resolution of 7.9375 µm

.

This differs from the resolution used by standard HP-GL plotters. The use of master commands reduces the output.

The syntax:

The SMCUexpects a separator, which may not be a digit or uppercase letter, between the command parameters. A new command can follow a parameter without a separator. The last character transmitted in a command file must be a semicolon or a line feed character (0A hex.).

Unrecognized commands are ignored by the control unit, but their parameters can lead to unwanted plot absolute or plot relative commands.

Symbol Meaning

{...} The contents can be repeated any number of times.

() The command parameters are contained within these brackets.

[] The content of these brackets is optional and does not have to be

included.

Appendix

Cl (r{,ß}){;}

Circle

Dws a complete circle with radius r around the current position. Resolution ß is ignored as the maximum resolution is always used when drawing.

EA (x,y){;}

Edge Rectangle Absolute

Draws a rectangle defined by two corner points diagonally opposite each other. The first corner point is determined by the current position and the second by the absolute coordinate (x,y).

ER (x,y){;}

Edge Rectangle Relative

Draws a rectangle defined by two corner points diagonally opposite each other. The first corner point is determined by the current position and the second by the relative coordinate (x,y).

IN {;}

Initialize

Returns the control unit to the its status after switching on. This restores all default settings.

IW (x0,y0,x1,y1){;}

Input Window

Restricts the XY axis working area to a window with the corner coordinates specified.
