i have worked with mach3 in "MILL" but now i want to learn how to work with that in "PLASMA"
in some videos i saw that nozzle moves to the desired point when it reaches to the destination point it moves down and then up and after that the PLASMA turnes on and it stops for a short time(delay) began to move.

How mach3 do this operations in its program routine
i think that the PLASMA operation is so,but if i make any mistake please describe.

in my country i can't buy any thing using internet .
THC basis is on voltage difference between the nozzle and the plate that it compares with a refrence voltage .the nozzle and plate distance tunes depand on the voltage between nozzle and plate.
is it a complicated project you think or it can be done easily with a microcontroller?

best regard.
