Sheetcam and trying to generate spotting gcode.

After fixing my .ini file so the correct number of SPINDLES was used, I have spotting working. But. If i create a file with both spotting and cutting, it will fail on the first cut attempt with the torch going down, igniting and then going up again, over and over. If I separate the two, then it works fine. I'm using the latest post file from Phil as well as the latest qtplasma. in the attached file, I seem to get to line 4090 at which point it fails.
;begin material setup

N04010 M190 P23 (45 amp 14ga mild steel material)
N04020 M66 P3 L3 Q2 (wait for valid change)
N04030 F#<_hal[plasmac.cut-feed-rate]>
N04040 ;end material setup
N04050 M5 $0(cut stop)
N04060 ;end operation #30, cutting
N04070 ;
N04080 ;begin operation #31, cutting, 1.34"
N04090 G0 X2.76051 Y3.80271

I'm actually thinking that it fails at the M5 $0 which is wrong I think. that should be M5 $2 (spotting)
The second last spotting op that succeeds has a M5 $2 in it, but the last one has a M5 $0.

They all seem to be cutting operations, not spotting.

You need a tool named "Centre Spot" or "Center Spot" and a drill operation, or try the sheetcam post earlier in this thread.

I do have the Center Spot tool defined. And I'm using the latest post from you dated in 2021. I just uploaded the wrong file


Line 4050 is wrong. It should be M5 $2 not $0 and for whatever reason this causes an issue with my Z axis. Basically it will never go past that line.

sure.

That is really weird. I was using 7.1.11 and after updating to 7.1.12, I was able to load the saved job file. There seem to be some issue's with sheetcam. If I use a drilling op instead of the center spot, I can not have both drilling and cutting in the same file. As for the Center Spot op, The last center spot does not have a M5 before the Material Setup. Therefore the M5 attempts to stop a cutting operation instead of a Center Spot operation and of course this is where linuxcnc fails. It really does not like a M5 $0 attempting to stop a M3 $2.

looks like that will work. I posted on the sheetcam forum, since I believe that the issue shown above is still a bug. Not completing the operation before changing the setup is just wrong.
