Wild TA-10 Vinyl Cutting Plotter

Status

We figured out how to talk to it, use the DB9 to connect to it; 9600BPS 8n1 , hardware flowcontrol (rts/cts).

Refer to the documentation below about how to get the device to do it's work for you. Currently your options are:

• Use a specially prepared version of ps2edit that has a driver for 'ta10'; this will provide documented below
• Use the 'EuroCut Basic 7' program under windows if you can find a valid license
• Use the information in this document to write your own driver/application that sends commands directly.
• In the near future we hope to have the ps2edit work lead to a CUPS-compatible postscript printer usable over network

The machine has some parts that have been fixed/restored to proper functionality. Note that the machine is a work of fine mechanic art and is not for [DAS GEFINGERPOKEN UND DAS MITTENGRABEN. IST NICHT FÜR GEWERKEN BEI DUMMKOPFEN.]

This means that you will need to be careful with it. Consult someone experienced with the machine if you are going to do something *special* that risks jamming the machine, putting undue force on parts, make dust/smoke/shrapnel, etc.

Please also take care of personal safety. The tool-arm does not have a soul nor eyes. It wont care that it smashed into your glasses while you were too close to it.

Project Box

There is a project-box related to this device. It contains a number of parts and accessories to the device. Including the cutter-head and adjustment-collar. Please return the pens and/or cutter-heads back to the project-box for safe storage. There is a significant risk of the tool-grippers breaking if a tool is left stored on the device when not in use. Since they are stiffly fixed to the tool-gripper, a simple bump against one of the tools might cause the tool-gripper to break (again).

Features

Tool head

The device has a tool-arm (grey) with a default solenoid-based toolhead attached to it (orange).

The toolhead has two metal clamps with thumbscrews to insert a tool into (typically a pen or a tangential cutting tool). These clamps are delicate and care should be taken to not put too much mechanical force on them. Especially sideways force will likely result in breakage; be careful! The toolhead has a set of work-lights below it that light up the work-surface. They can be switched on/off with a switch on the tool-arm. The tool-head has a set of knobs on it. The black ones allow you to push the tool down manually, the silver-ones allow you to 'unblock' a tool if it becomes jammed in some way. There is a power-connector between the two tool-clamps that carries current for accessories (FIXME: specs required)

The default tool-head can be either replaced or augmented; bolt-holes on the side of the tool-arm allow you to fix extra equipment to it. An internal DB9 interface (under orange plastic) allows you to create an interface between plotter and extra tools. The DB9 carries solenoid-signals, light-power, accessory-power and possibly more (FIXME: documentation needed).

Bed

The device features a large cutting bed made of a transparent material that lets the light through of the dimmable Tube-light array behind it. Please find the white dimmer-switch on the backside of the device. The bed seems to be fastened to the frame of the device with a series of spring-clamps which seem accessible for replacement/adjustment by accessing the inner space of the table by undoing the back-panels on the back of the table. When using markers with NONpermanent ink (aka: whiteboard markers), one can easily test a design first by drawing directly on the bed's surface. The bed is then easily cleaned with a damp cloth.

Tilting

Also on the backside is the tilt-lock handle for the table's angle. BE CAREFUL when pushing the articulated handle up; the weight of the table is considerable! The telescopic arm does have a spring inside to help carry some of the weight, however. Be ready to support weight and slowly unlock the handle until the table starts to move. Make sure to relock securely. Table can be put down until perfectly level and up until nearly upright. BE CAREFUL PUTTING IT TOO FAR UPRIGHT; the weight of the table is then all on one side; there is a risk of the device FALLING OVER FORWARDS.

Control Unit/Base

The whole table is supported by a hinge-assembly and a telescoping arm (see tilting, above), on a base-unit which houses the power-supply and the control-unit of the device. The control-unit consists of an small internal 19" controller-card rack which houses a number of user-replaceable cards. Some are obvious communication and servo-amplifier cards; others are less clear. Card-positions are listed on the inside of the hatch. On the other side are a series of fuses and an hour-of-service counter on the hatch that covers the Power-supply of the device.

Control Pendant

There is a control-pendant that's attached to the device by a cable and can be fixed to the side of the table by means of the magnet on the back of it. It provides step-precision control of the head, choosing the pen and setting a number of parameters of operation (window, origin, etc). Keeping the direction-control buttons for longer periods will increase the speed of the head.

Control buttons

The control-buttons on the edge of the table also allow for a number of the controls that are possible via the control pendant; as well as allowing you to switch the device on/off and such.

Material trough

On the left side, next to the cutting bed, there is a trough that allows rolls of base-material to be kept there; unrolling a section of it across the bed for cutting/plotting. There is a matching tool-holder that fits in this trough that houses pens suitable for the machine.

Tool-arm

The tool-arm is where all the magic happens. It has set of two tool-mounts available allowing you to switch between them using the controls and/or the protocol. The arm will move a fixed offset up/down when switching tools. The inserts for the tools are actuated electro-mechanically and care should be taken to not stress these too heavily lest they break (NOTE: THE TOP ONE IS CURRENTLY BROKEN AND SHOULD FIRST BE FIXED! EITHER BY USING A SHIM OR OTHERWISE GLUEING/WELDING IT AGAIN).

The tool-head has a number of sockets, switches and other features. There is a multi-pin socket for connecting the cutter-head to (see later). There is a switch for turning on/off the lights (NOTE: The lights are found below the tool-arm and need fixing; one of the tube-lights is missing. A little metal ring is dangling on a wire currently the top side , underneath). There is a little white socket that seems to be for connecting some manner of sensing probe to, or perhaps it carries current for use with a tool. Another socket can be found between the two tool-clamps; a barrel-jack that likely carries potential for optional accessories.

The tool-clamps came/come with inserts that allow straight clamping inside of them using the supplied thumb-screws on the side of them. One of these inserts remains and has been stored in the project-box related to the cutter.

Cutting-head

There is a cutting-head accessory that came with this device. It's main function is as a servo/stepper actuated roto-knife that makes sure that the knife cuts in the direction of movement that the tool-arm is heading. This prevents the need for resorting to a swivel-knife that'd have less perfect cuts in designs with a lot of angles. The cutting-head comes with an adjustment-collar that allows for easier depth-control. Find and return both the cutting-head and the adjustment-collar to the project-box they are stored in. Since the cutting-head protrudes quite a lot from the tool-arm, there is a great risk of damaging the tool-clamp if the cutter-head is left stored in the device when not in use.

Manual

plug in the power lead

hit the 'power on' button. make sure the 'manual stop' button is not pressed otherwise nothing will work

there is a VIA C3 pc, made of lego. it needs to be plugged in and attached to the network via the lack rack. it currently sits on the base of the plotter itself.

Log on to the machine via ssh on IP address 10.0.20.23 - for an account speak to brainsmoke/amx109/realitygaps/wizzup

The following only works for a single user, 'amran'. This will be ported to work globally/via a web interface soon

login to the box. make sure your user is part of the dialout group.

run the script located at

/home/amran/print.sh <path to your postscript file here>

this script will setup the correct port settings and do all the conversion and make the plotter 'print'.

Old information

Check the Serial port settings with

sudo stty -F /dev/ttyS0 -a

The settings should be 9600 8n1 with flow control on.

speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^H; eof = ^D; eol = <undef>; eol2 = <undef>; swtch =  <undef>; start = ^Q; stop = ^S; susp = ^Z; 
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 5;

-isig -icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop -echoprt -echoctl - echoke

the command to set these settings is

sudo stty -F /dev/ttyS0 9600 crtscts

Now, create the file you wish to 'plot' Save as postscript (.ps)

On the machine run

pstoedit -f ta10 <yourfile>.ps

this will output commands to the screen.

if you output to a file, this can be used to send all commands to the plotter in one go. the output file will also contain the 'initialisation' commands.

to print to the machine open a screen session

sudo screen /dev/ttyS0 9600,ctsrts

and paste in your commands

to exit press CTRL+A followed by K

UPDATE: works with echo command - as root, do

echo -e ":83\r\n:32\r\n:520,20:E3500\r\n\rP2\r\nU0,0\r\n:715\r\nU 0,0\r\nU 13424,0\r\nU 13424,10532\r\nU 0,10532\r\nU 0,0\r\nU 0,0\r\n" > /dev/ttyS0

UPDATE: pstoedit outputs wrong carriage returns

the file generated by pstoedit outputs \n, the plotter needs \r\n
cat test | perl -nwe '$_ =~ s/\n/\r\n/g; print $_;' > testRN

Plans

The current plan is to work on fixing a number of defects on the table and making a software-layer between the 'broken hpgl' of the device and 'the real world'. Part of this work will be done during Tinkering thurs/tuesdays.

See 'features' for some of the jobs that need to be carried out.

Protocol

The serial protocol used appears to be an HP-GL like language. We captured the follow commands from the Eurocut driver. This driver always sent the same commands first, probably some initialisation:

:83
:32
:520,20
:E3500
P2
U0,0
:715

Selecting the universal head in Eurocut changes the :5 command to

:5250,250

To select pen / tool number <x>

P<x>

To set the move speed:

:7<speed>  (1 - very slow, 50 - fast)

To move the pen in down position:

D 13140,6460

To move the pen in up position:

U 13140,6460

Example of instructions that work with the machine:

:83
:32
:520,20
:E3500
P1
U0,0
:715
U 0,0
U 13424,0
U 13424,10532
U 0,10532
U 0,0
U 0,0

This draws a simple square (see the commands starting with 'U'). The P1 command does the pen select (P2 for the other pen).

Resources

Software that lists these plotters explicitly as supported:

- SignTools 4 - an add-on for CorelDraw, Demo Version available

- Some references (eBay auctions et al) list HPGL (overview) as a way to talk to it. But often together with some interface box so this might not work for ours.

This program works with the plotter: - EuroCUT Basic 7 http://www.eurosystems.lu/index.dml?unten=software/EuroCUT_Basic-eng.htm&von=html
