Re: Proma THC, Mach 3 sheetcam settings help
added a fix to restore XY position precision after a torch probe cycle, in Reference() function. This will avoid grbl and most other controllers error33, thrown on arcs that don't pass the 0.005mm tolerance of begin and endpoint falling on the arc path. These are pretty common to occur on lead-in ar...

Re: Proma THC, Mach 3 sheetcam settings help
no problem, you're welcome. I was a bit in a hurry the other day, and I recalled seeing some odd stuff in the .scpost, so I took another look this morning and fixed up the oddities. Please let me know if I broke anything, of course hopefully not. * there were two OnArc() functions defined, only the ...

Re: Proma THC, Mach 3 sheetcam settings help
All 3 issues should be fixed in the attached version. The lines added and changed in the original version are flagged with "--LDC"... re. refDistance, the original was accumulating the cut length and rapid distances for compare to refDistance, to determine if a torch probe cycle is necessa...

Re: Rules not working as expected
Les commented recently on path rules in another forum, perhaps his comments apply to your situation also, or at least in part.

Re: GRBL Plasma w THC, Torch Touchoff, and Rotary
Version 28.7 Inspired by @ROTM from this recent post and drill pecking tutorial, I adjusted my .scpost accordingly. Thanks @ROTM. https://forum.sheetcam.com/viewtopic.php?p=31626#p31626 Note though that I'm choosing for now to not change the tool or amps for plasma drilling and pecking operations. I...

Re: Plasma pierce hole not working (where is my mistake?)
so I simply added this simple template example of OnDrill() and it produced gcode, however I don't know the gcode stmts for this controller so I don't know if its correct. But you can tweak the OnDrill() function if need be at this point. function OnDrill() OnRapid() OnPenDown() endZ = drillZ OnMove...

Re: Plasma pierce hole not working (where is my mistake?)
it appears the problem is that there is no OnDrill() function defined in the .scpost.
I'll put a basic version of OnDrill() in and see how it goes.
btw- I like the coded model to define external vars and custom options, well done. I saw one a few ago similar, or may have been the same one.

Re: Plasma pierce hole not working (where is my mistake?)
you also have the first "shape" at 0,0 it appears. I seem to recall some obscure SC bug a few months ago when the first start point is at 0,0, and that was about the time I was customizing my OnDrill() function and testing it. Try moving the part off 0,0 origin before we go to far down thi...

Re: Plasma pierce hole not working (where is my mistake?)
could be any number of things. does your .scpost have OnDrill() customized ? pierce delay is 0. Does the torch fire at all ? pierce hight - cut height is only 0.020", that's going to be quick. best if you post your .job file and .scpost file, and the .nc file you're getting. Easier to diagnose ...

Re: GRBL Plasma w THC, Torch Touchoff, and Rotary
version 28.6 28.3 change double Torch Probe Cycle to single, 28.4 added feature to bypass Torch Probe Cycle if LdcTorchProbeTravel = 0. 28.5 changed OnDrill() pecking parameters. LdcDrillPdPct -- Plasma Drill peck tuning, % of pierceDelay, 0-150 LdcDrillChPct -- Plasma Drill peck tuning, % of cutHei...

Re: Sheet cam GRBL torch probe post processor
You have to adjust the floating torch distance which actuates the probe switch. I arbitrarily set it at 10mm. Given you report that the torch is cutting 0.25" too hight, your value is going to be 10 - 6.34 = 3.66mm Edit the .scpost and replace this function with this corrected code. I also made...

Re: plasma turn on coolant
I’m not sure what indication the simulator would give. Have you looked at the Gcode file to see if the M8 and M9 statements appear?

Re: Sheet cam GRBL torch probe post processor
Try the attached, it produces the following gcode, PH being 3.2mm in the tool, XY being the pierce location.
See the function DoTorchProbeCycle() to make adjustments.

Re: plasma turn on coolant
you're welcome. please report back how the misting approach goes in terms of the plasma cutting process. I run with a water table. Some use a down draft table. I have not researched this extensively, but what I have read and experienced is that the purpose of the water or down draft is to capture or...
