THC Test causes steppers to sudder and move

Pretty bummed… I was cutting a few things, no issues, everything as it should be. Go to start a new print and everything goes haywire. Replaced the consumables even though they looked perfect and did a new test just for safe keeping. Still going bonkers. As soon as the software triggers the plasma the steppers start moving and the laptop screen goes blank until it errors out.

But what plasma machine are you using and it’s your laptop plugged in during the cut?

I posted his question in another thread…this is the issues I believe
Amico APC-70HF plasma cutter…
