= HOLD UP, THIS IS NOT THE TOOL YOU WANT! WE'VE REPLACED IT =
See [[Tormach 1300PL CNC Plasma Cutter]] for the new machine. Everything on this page is invalid and kept for historical purposes only.

== Status ==
== Status ==
As of 12/21, the table is essentially borked. Coolant splashed into the electronics box, shorting it out. There have been a number of issues with the table over the years and as of right now the thought is to scrap the existing machine and replace it with a new one.

== Authorization ==
Authorization requirements:
* This is not a commercial machine; it was hand-built at PS1 and as such there is no website to check, nor any manual to read. You must be willing to accept the fact that the machine can be quirky and you may have to do some troubleshooting when using it (hopefully not, but ¯\_(ツ)_/¯).
* You should be familiar with how plasma cutters work (at the very least, read this: https://en.wikipedia.org/wiki/Plasma_cutting). If you can swing it, please get authorized on the Miller handheld plasma machine beforehand; this is not a requirement, just a useful suggestion.
* Read all of this page about the machine: https://wiki.pumpingstationone.org/CNC_Plasma_Cutter
* Read and be willing to add your experience/knowledge of using the machine here: https://wiki.pumpingstationone.org/Talk:CNC_Plasma_Cutter

Fill water table if not filled already. Takes about 35 minutes to fill. Be sure to have the splash guard on it so when it's filled the air does not spray water everywhere.

=== Running A Job ===
=== Creating a Job ===
# Start SheetCam
# Import a Drawing from the File menu. Remember that the origin is at the bottom left on Sheetcam, and the origin on the machine is back left.
# Click on Operation => Plasma Cut
# Unfortunately most settings can be changed by other users between jobs. Some that seem to work:
** 130 ipm feed rate
** Tool: T11: Plasma 12 Gauge (or whatever gauge you're cutting)
** Note that Inside/Outside offset determines if you're trying to cut an inside edge or outside edge.
** You may need to select a layer.
# Click OK and the path should be generated and display.
# To create a TAP file go to the P icon at top left. That's post-processing.
# It should save as type G-code/.tap.
This is now a runnable job.
=== Running a Job ===
Look elsewhere for turning on the machine, filling the table, turning on the plasma cutter.
=== Starting a job from a particular line of code (needs update)===
# Start Mach3 CNC
*Run from here
# You should be able to move the gantry using the arrow keys to get into position. You MUST start your job over metal - it does an auto z-axis zero/home.
*Select next line
# If "Reset" is flashing, click it to reset the connection.
# Test the job without the plasma on if you want.
# Turn on plasma cutter and close curtain.
# Click Cycle Start (green).
=== Starting a job from a particular line of code ===
*Double click on the code preview window to see the line number that mach3 assigns to the line. (mach3#:sheetcam# - example 11:N110)
*Be careful and be ready to hit the e-stop
*If you don't know the exact line to start from, find the line directly after a TCH off before the line the job stopped. If it errors on that line try moving to the next movement line. The job should do some air moves until the next probe.
*Type the number of the line in the area "Line:_____" right next to the red stop button.
*Type Enter. The gcode preview should jump to the line you typed in.
*Click the "Set next line" button.
*Click the green Cycle Start button.
=== The job stopped while probing (not z-crash or skipping steps) ===
*Record the g-code line where the machine stopped.
*Check to see if there are any errors. If there errors send a message to Slack about them.
*Be careful and be ready to hit the e-stop.
*Click "Reset" twice (the first time goes into estop mode and the second time comes out of it).
*Click "Cycle Start". The cnc should move to pierce height and then start cutting (generally running correctly again)

==== Error: "Probe ignore, activated at call for probe" ====
'''Tends to happen when attempting to reignite torch after first cut'''
Causes:
*THCv set to high, e.g. cutting 1/4" steel @45A recommended THCv is 115, lower to 114 or until the torch ignites successfully
== Sheet Cam ==
https://www.youtube.com/user/arclightdynamics/videos has good tutorials.
Sheet Cam settings always use the last setting. So double check it's what you want.
Origin is bottom left. Origin on the machine is back left. Brown box is the material size, but it doesn't need to be set.
It's a good idea to have a bounding box on your work so it's placed correctly.
Isolate paths by selecting them then put them in a new layer. This includes the previously mentioned bounding box.
Cuts can be inside edge, outside edge or on the line. A lead in is a good idea to help keep the cuts clean. Lead out has not been tested but may help.
The post-processor to use for this machine is named 'PS1 Plasma'. It's already included in the list of post-processors on the installed copy of SheetCam.
=== Manual Controls ===
* Arrow keys move X/Y
* Shift PageUp/PageDown moves the Z axis
Click the zero button to set home. (this is from memory, please correct -- Burton)
