Sheetcam THC problem with Swiftcut

Post by samT »

hi all,
its been a while since i have used my plasma table and i noticed today that the gcode that is generated from sheetcam does not seem to be telling my swiftcut swifty1250 to turn the THC on.
in the Gcode, it is only telling the machine to turn the THC off, but never telling it to turn on in the first place. as a result the THC isnt doing anything and i have had a few torch crashes today.
with the original software from swiftcut it does tell the THC to turn on, the problem is only when i use sheetcam.

am i being daft and missing something obvious that is stopping the gcode from generating the THC on command?

thanks in advance

It sounds like you may not be using the correct Post Processor for your table. If you have a G-code that has worked in the past it will name the Port Processor in the top lines. Here is an example from one of mine.

; file name: 4 line loop X dirction cut.tap
; date and time: Mon May 20 2024 11:50:46 AM
; postprocessor: LinuxCNC PlasmaC.scpost rev: 0.5

You can contact SheetCam and request the correct Post Processor if needed.

I thought that would be the answer.
I am using the post processor provided by Les a while ago. I will contact them directly, I just wanted to check I hadn't missed something first.

Thank you very much
