When THC mode is ON torch never goes to rapid clearance
HI. I'm having trouble with my CNC plasma tabel. I use Mach3 and Sheetcam, both have their licenses installed. I have set the rapid clearance 30 mm on sheetcam and in the post processor i use says that the torch will be referenced out at start of cut and every 50mm of movement thereafter but that never happens. on the G code is a G00 Z30 line after each cut but it gets always ignored and the torch just goes to the next cut with that same height it was cutting and catches on the very warped material i use. . . but when i turn off THC mode on mach3 it executes the line just fine and after each cut it goes 30 mm up and than moves to the next cut but i cant just cut without THC because the material is very warped. I don't know if it has something to do with mach3, sheetcam/post processor or my breakout board!? here are some of my specs and i hope someone can help me
CNC plasma table specs:
Software: Mach3, Sheetcam.
Hardware: Chinese breakout board with USB connection, PriceCNC AVHC10 torch height controll, Z axis with floating head G31 probing
Post processor:
function OnAbout(event) ctrl = event:GetTextCtrl()
ctrl:AppendText("plasma AVHC10 post processor\n")
ctrl:AppendText("\n")
ctrl:AppendText("Modal G-codes and coordinates\n")
ctrl:AppendText("Comments enclosed with ( and )\n")
ctrl:AppendText("M03/M05 turn the torch on/off\n")
ctrl:AppendText("Incremental IJ\n")
ctrl:AppendText("The torch is referenced at cut start and every 50mm of movement thereafter\n")
ctrl:AppendText("Designed for use with Mach3 and PriceCNC AVHC10\n")
ctrl:AppendText("Post variables:\n")
ctrl:AppendText("refdistance - set the distance between each reference\n")
