post problems

[cdindustries]

I am having a sudden problem with post 27E.

As of this week when I run the post processor, it no longer turns on auto THC, or call a cut height. I can not figure out what has changed. The file will run, touchoff, go to pierce height and cut at that height only. Torch never drops to cut height, and thc never comes on.

Running Command CNC on a mini computer. Sheetcam version is 6.1.57
I would think it's a problem within sheetcam, but I am unsure of where to start looking.
I have attached a copy of good code

I'm guessing it might have something to do with this.
First code has this
M68 E0 Q89 (Auto Preset is not active )
Second has this
M68 E0 Q80 (Auto Preset is active )

It's probably trying to autoset the volts, but not sensing properly. Just a guess. No experience with commandcnc.

djreiswig Thanks for the reply. Auto set is a THC control setting that can be turned on and off. I will have to look into that. I will have to look up the code because I am not sure what the auto preset refers to. This has me stumped because i have not made any changes within sheetcam,and this problem popped up all of a sudden. I am convinced at this point that i have inadvertently changed something and can't figure out what.
