Thomas, I don't use mach3 THC. I developer of the Neuron.THC.
Command M10/M11 or M10Px/M11Px use in g-code laser cutting machine, plasma, oxyfuel...
This command is regular Mach3 function and I hope It's support by CSMIO.
Smooth stepper support this commands and has separate settings for this in the configuration menu. Full support has and HiCON motion controller.
In Mach4 we need this command too (M62/M63 - Mach4 embeds the IO into the motion data that goes to the motion controller and then to IO ports)
Thanks!!!
