Im guessing most of my issues a related to having a very cheap Chinese plasma cutter, im still looking into what actual plasma cutter i want to go for. Can anyone take a look and the cut quality and give me some direction. The material is 2mm and im running 30A at 50PSI with a 0.8mm tip. Ive carried out auto levelling but getting mixed quality in cuts. ![WhatsApp Image 2026-05-16 at 12.33.50 PM](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/5/57e7e660ee23c6f1aee1f4040b63a41d50971416.jpeg) ![WhatsApp Image 2026-05-16 at 12.33.50 PM (1)](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/1/12e52fe5240c7a42ad7c1e16f3dce5197553d66e.jpeg) ---

Assuming your cutting steel and not stainless… 2mm would be better at 45 amps and at those amps, 1.5 mm cutting distance Pierce height 1.8mm .1 sec pierce delay 6500mm/min cut speed Verify your Z heights! Measure what you really get versus what you program. You may need to comp the programed height to get the real number you want. I think you may want more air too but that is whatever your particular plasma cutter needs to be happy. I’d think 75-80 psi would be better. It’s one of those things where it is best to make a series of test cuts, like 2" straight lines, and the only thing you change is air pressure. You’ll see the effect it has. ---

If 30A is your max, Change pierce delay to .3sec Try around 3500mm/min feed ---

@Jdd I can’t even interpret that…
