I think the pause button could be used pin 2.12 or 2.11
use the m3 to start plasma but it also triggers the pause button.
use the thc to release the pause button.
@Aaron_Pence with a little handy work on the driver you can make the eagle plasma work great. You need something with removable stepper sticks. A GRBL board works fine.
Pull the STP/DIR pins out from the top of the stepper stick and out of the bottom of the board.
Output the pins from the board to the eagle product, input from the eagle product to the stepper stick. Done.
Works well. No Gcode or Mcode mods required. Im sure there is a way to get a smoothie to do this too, and we are working with another board group to make these pins accessible for this and another control interface we need.
went with a vhc-300 THC with a 24vdc torch lifter off amazon mounted on z next to spindle. THC has pierce delay, arc voltage height control, pierce height, and ok to move all built in.
planing to us switched output G1- G3 to turn plasma on.
not sure if this is best. could use custom m code.
I’m worried the pause input wont be executed fast enough in smoothie.
thc I’m using from aliexpress $250 with divider board.
the divider board for my cutmaster would almost cost more.
