Looking for some help again!! Same issue, but i think a different cause, although probably still post processor related! I have changed to a different, more simple Torch Height controller and am using "Mach3 flame with THC - G31" post processor, which i havent modified apart from setting t...

Tried a different post, and now i am seeing plenty of probings in my G code,(that sounds a bit rude! ) so i am happier with that,
thanks for the info!!

Ok cheers I will need to check over my post code, I had simply copy and pasted what i thought was the relevant parts from another processor into the one i was using with my THC, but i must have missed some part of it! I now using a Proma 150 THC and have an ohmic sensing probe input, so i might just...

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 bet...

hope you dont mind me hijacking this thread,
But i am struggling to get my Razordance THC to work, and wondered if you have any tips/things to look out for?

cheers!

So i have found the problem i think! I just removed the G31 routine i had put in the OnInit() function, but have been able to keep it in the OnPenDown bit, I think i was just being lazy and hoping to get it to probe and zero the z axis on its own at the start of the program, I will just have to reme...

Well i had another play around and cant seem to get that program to work, Im fairly sure its something to do with the post processor, I did try another simple test drawing that was using a very generic plasma post processor with no probe routine so i just manually zero'd the Z axis to the top of the...

I do have a torch height controller, and i am fairly sure it is turned off, i will have another play after my dinner!
thanks for having a look at that code for me, its good to have another pair of eyes look over it!
cheers

this is the post processor function OnAbout(event) ctrl = event:GetTextCtrl() ctrl:AppendText("Mach3 + razordance plasma post processor\n") ctrl:AppendText("\n") ctrl:AppendText("Modal G-codes and coordinates\n") ctrl:AppendText("Comments enclosed with ( and )\n&qu...

here is the first few bits of the gcode, I cant see anything wrong here, but i am just a beginner! N0040 G21 (Units: Metric) N0050 G53 G90 G91.1 G40 N0060 F1 N0070 S500 N0080 G31 Z-100 F400 N0090 G92 Z0 N0100 (Part: smallcleats-Sketch) N0110 (Operation: Inside Offset, inside, T1: Plasma inside, 10mm...

I have got the Z axis zeroing perfectly when using MDI in mach 3, (g31 z-100 f200) and then (g92 z0),
Also I am running the program without the THC clicked on in mach3 and the plasma cutter switched off, so just a dry run, not sure if that would cause the strange offset?

I have been re-powering a Plasma table recently, at the stage of first test cut, starting to get the hang of things now, but I am having a strange issue where after zeroing the z axis off the material, the torch then seems to stay about 10mm higher than it should at the pierce and cut heights as wel...
