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...

Re: plasma turn on coolant

This is a multi-step process to setup but you'll find the process handy for...

Re: G-codes
I'm not aware of a "free version" of sheetcam. The real sheetcam product downloaded from sheetcam.com clearly states "this download is limited to approximately 180 lines of generated code. You need to purchase a license to remove this limit. "

Re: starting point issue
you'll have to be more specific, best if you post your .job file and cite which version of sheetcam you are using.

Re: Building & setting up a rotary tube cutter
Welcome to the forum. 1. Will I need a torch height control integrated with this machine? I'm thinking not, but maybe someone will tell me otherwise. If your machine will have a tube support/bearing which slides axial and is integrated with the torch mount or very near it, then likely no THC will be...

Re: GRBL Plasma w THC, Torch Touchoff, and Rotary
update: version 28.2 28.1 added LdcFastProbe var 28.2 added LdcProximityDist feature, supporting vars, and logic. -- proximity distance in mm to skip a Torch Probe Cycle before piercing if current location is within proximity of a recent previous location. A value of 0 turns off the feature. Using t...

Re: Set custom post options
WOW! I studied " Mach4 TMC3in1.scpost". That is quite a DefineCustom... all of it - logic! Masterful. Are you trying to add a "Mechanical or Ohmic" boolean choice option to the large list of options in your clone/merger of this scpost ? OR do you just want to use one or a couple ...

Re: Torch Height Problem
Correction, rather than 'return' from OnPenDown() if inside proximity distance of a previous pierce, you'd still want to perform other key OnPenDown() functions such as firing the torch and pierce delay. Also, the initial value of the ProximityLastX, and Y, should be a large value such as 1e+17, so ...

Re: Torch Height Problem
I found "PremierPlasma CNC Floating Head.scpost" in the sheetcam post lib. If this is what you are using, then... It certainly has code to skip torch probe cycles, but its not a proximity of next cut, rather its an accumulated distance of all motion by XY on straight line measurements betw...

Re: Torch Height Problem
My research on Premier Plasma systems is they use Proma THC SD THCs. Is that what you are using ? If so, then you are correct in understanding the problem, since this THC is operates autonomous to Mach3, and can/will leave the torch height out of position relative to where Mach3 thinks it is, where ...
