I'm in the middle of a 4"x8" Plasma table project,
I did download Mach R1.84.000 demo version
But I can't get the right configuration to make the torch to go on/off as I been seen in some youtube videos
Can anyone help me to go the right direction?

Some times the torch stays on even when is not cutting, other times move likes is cutting but no flame from the torch

regards,
uu
