General Mach Discussion / Another THC problem
« on: November 13, 2020, 02:37:04 AM »
Hi All,
I am fighting a THC problem at the minute and it is very strange.
For starters the basics are:- yes I have a registered version of Mach3, yes I have tried the "enable THC even in off" both active and not active and I have written "StartTHC()" in the M3 VB script and "EndTHC()" in M5. I have the three diagnostic LEDs working correctly for THC on, Torch Up and Torch Down on the given signals.
The "THC ON" input is working and when signal low creates a feed hold, once high again program continues. So to me this is working as expected. The issue is that I have no Z-axis control whatsoever when arc active (THC ON) is on or off. I have tried to use the THC input signals, Emulated inputs from keystroke hotkeys and have tried to manually jog the Z axis up and down to no avail. I can not get any Z axis movement whatsoever but the diagnostic LED's are giving the inputs to move.
Is there a command in VB or G/M code that allows axis override while program is running or is there a setting that I have missed in Mach itself? I know there is "JogOn()" command and I have considered putting it in my M3 script but from my understanding this is to move the axis with position input and then "JogOff()" once executed, not for external jog signals or am I not understanding it correctly.
