Hi everyone,
I've built my own CNC Router (based on the Avid CNC) Hybrid (Mill & Plasma). The Milling works flawlessly, but I am really struggling to get reliable plasma cuts.
My software/hardware setup is as followed:
- Mach4
- TMC3in1 THC
- Hypertherm 45 XP
My main issue is, that on a regular basis (on every second cut - if I try to do bigger cuts, it occurs on every cut) during the cut the "ARC OK" signal is being disabled, which leads to a stop of the cut. The cut does not stop immediately. First the torch goes off, then the machine moves for 3-5mm and then stops.
I can cut rectangles (50x25mm) with mostly (7/10 times) no "ARC not OK" Error, and the cutting height (1,5mm) and speed seems to be ok, too. But if I am trying to cut bigger pieces, the errors appears every time.
I can't figure out, where to tackle this issue...
Does anyone have an idea for an approach to solve this issue?
