everything seems ffine to me,..,

Code: [Select]
N0010 (Filename: 1.tap)
N0020 (Post processor: Mach3 plasma.scpost)
N0030 (Date: 28/02/2018)
N0040 G20 (Units: Inches)
N0050 G53 G90 G91.1 G40
N0060 F1
N0070 S500
N0080 (Part: 1)
N0090 (Operation: Outside Offset, LAYER_1, T1: Plasma, 0.0561 in kerf)
N0100 M06 T1 F80.0  (Plasma, 0.0561 in kerf)
N0110 G00 Z1.0000
N0120 X0.6134 Y0.6013
N0130 Z0.0000
N0140 M03
N0150 G03 X0.7726 Y0.6873 I0.0366 J0.1227 F80.0
N0160 X0.7726 Y0.6873 I-0.2726 J0.0813
N0170 X0.6865 Y0.8466 I-0.1227 J0.0366
N0180 M05
N0190 G00 Z1.0000
N0200 X1.1256 Y-0.1384
N0210 Z0.0000
N0220 M03
N0230 G03 X0.9976 Y-0.0104 I-0.1280 J0.0000

Hmm, N0100 & N0130 items seem odd to me

Tool change is not usually used in plasma, why is it going to Z0 before the pierce??

You should never, pierce at zero height, unless this is a scratch-start plasma??

ok this code should work, and restore original feedrate

pierceHeight = 0.5 'enter here a value for wanted pierceheiht

   orgspeed=GetDro(18)    
   code "F30"
   code "G31 Z-1"
   While Ismoving()
   Wend

   code "G00 Z" & GetVar(2002) 'go back to the  probepoint
   While Ismoving()
   Wend

   code "G91 Z" & pierceHeight
   While Ismoving()
   Wend

   code "G92 Z0"
   While Ismoving()
   Wend

   Code "G90"
   Code "F" & orgspeed
   


Is this necessary? I have my my plunge rate in sheetcam set at 20ipm.

My pierce height says 0” in sheetcam, because with the edited m3 macro, i was having to control the pierce height in there.

ok ihave run your code on my PP testmachine.

deleted N100 toolchange not necesary.

run it with THC on but no Inputs connected. everything was ok.

can you for a test disconnect the THC Up/dn Inputs , but physicaly disconnect them.

 
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

yes because you have a "variable" cuttin feedrate but probing feedrate should allways be the same.

So leave THC on, and inputs active, but physically remove the inputs into my g540?

sorry i modified N100 to N100 F80 to Keep the fedrate

but disconnect only THC UP/Down inputs

Does the tool change code matter? It’s being generated by itself, but in MACH, my “ignore tool change” setting is checked. It has never been an issue
