Inserting an Output-ON M-Code in QtPlasmac g-code

Hey everyone.

I need to have the functionality of triggering M3 $0 S1 (plasma start) , and then, after a while, turn on another output. What G-Code can i use for this?

Then, I woud add also another one at M5 to turn off both at the same time.

M5 $0 (plasma end)
M7 $0

I cannot use the same output from M3 a timer for this, because the delay between both outputs will be variable and parameterized with the g-code.

Can i use the output from the marker? what if i also need the marker, are there other options available?

thank you.

qtplasmac may uses some of these internally.

Thank you Rod.

Assuming I use M64 P3 and M65 P3,

How is the “3” linked to HMOT CARD ssr output 3, in the HAL file?
I assume there should be some reference to the output number 3 in the Hal file otherwise it won’t work.

QtPlasmaC uses digital-out-01~03 internally so digital-out-00 is the only free pin available unless you add extra pins with num_dio when loading the motion module:
