Mach3 wont fire torch on plasma table
« on: March 22, 2018, 03:51:31 PM »
We have a Plasma table from Plasmaroute CNC that has stopped firing the arc.  The Software is Sheetcam and Mach3.  The included hardware is a Thermal Dynamics 120A, plasmaoute's motion control box, and their PR301 (THC301) for our torch height control.  Everything was normal until about a week ago when Mach3 started making our computer crash upon opening the program.  We cleared a few new windows updates, then reinstalled Mach3 and Sheetcam.  Mach3 seems to act and read all the GCODE normal until it gets to an M03 or M05.  It pauses like it should, it just wont try to start the arc.  if i let the program run and i manually turn the torch on and off in mach3 it cuts just fine.  what could be the issue?  at this point i cant get ahold of plasmaroute and have ran out of ideas.  Thanks for any input

i dont know your System/Hardware, and found no documentation about plasmaroute control box,
but normaly there is an Output (i.E. spindlerelay) witch Switches the cutter on/off (via M3 macro)

so if you post some Information of your box, and some screenshots of ports&pins -> spindle Setup.
also your XML would be helpful.
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

This is the exact setup we run on our system to the best of knowledge

can you please post your XML file?
 the Manual says noting about the used Signal, exept
all the torch control is done via LPT port 2.

Thank You

when you post a reply to attach the file
