Unsupported GCode Command - Solved - Rule applied that turned THC off in sheetcam, not recognized

Getting the message in the subject line when I try to open a tab file from Sheetcam into Firecontrol. Running fc 20.6.2 and the post file named: FireControl-v1.6.scpost Error is being reported on line 66 in the following gcode: This is my first attempt with new everything. Have been successful with manual line cut using THC. My searching indicates that this probably has something to do with THC. (line numbers added after the fact in wordpad for reference)

Thanks in advance!

M67 appears to be for synchronizing an analog output control. I don’t think this is necessary as Firecontrol is what controls the THC I believe. There don’t appear to be any special THC commands in the Sheetcam gcode files I’ve postprocessed.

Thanks! Problem partially solved: I deleted the 4 instances of that code line and the file cut successfully. I’d still like to explore why I’m getting those lines in my code.

I’d verify Sheetcam is using the correct post processor, and if it is, delete and reinstall it.

If it’s not, just make sure you load the correct one in Sheetcam.

Problem seems to be completely solved now. The issue appears to be that instead of writing my own tool library in sheetcam, I shoplifted one for another machine and modified to the cut60 chart in the manual. What I didn’t see were some underlying rules that imported as well, which were causing the issue. Now that I’ve run trial cuts to determine my kerf widths and built my tool library from scratch, the issue is completely resolved. Thanks for the help.

Ha! Excellent.

Feels great when you get it running right after a problem like that doesn’t it? I know when I had a CAM issue happen to me I was just glad it was my fault and not something that might crop up again at random.

Can you describe the rules that caused this? I’ve been updating post titles with their solutions to track solved issues.

Under Rule EOCAnti-Dive, which was under the always applied rule sets, the rule stated:

.565 in before end set feed to 100% and output code: DTHC-OFF

Thanks man.
