Hi

need help, I had a Pokeys57CNC and a Mach4 on a plasma cutter
If I send M3 in MDI for torch on, nothing happend.
If I removed M3 from Macro directory, M3 switch on the fire relais.
Any idea?

What was in the M3 macro in the macro directory? It kind of sounds like you don't want that macro to run, but if it is there is is going to run.

Hi

for better understanding:

I finished my machine, movement and calibration of the axis are ok.
Homing it work fine
Probing via the button "Touch" or the button "Probe" in the original Plasma screen from MACH4 installer works fine.
If I run first Gcode, program stopped after M3.

So I wrote small programm in MDI with some movements in X, Y, and Z and then M3 -> same again, stopped after M3.
No message, no error
So I found in WWW the regfile must be edited in some lines to come to metric, get the right voltage scale and so on, but M3 still do nothing

BTW, some guys said regfile should not be bigger than 41 lines, my regfile has round about 60 lines ??

So I removed the M3 macro from macro directory to see if there coming up any errors if there could not be found M3 macro.
But If I write M3 in MDI now "Spindle_on" come correct.
Seem there is an other M3 direct in MACH4 built in??

If I open the M3 in macro directory I see there will be a function "mc.fireon" called.
I could not find this fireon function anywhere??

Could you tell me with condition, inputs or positions must be present to begin M3 plasma working?
