Hey everyone. I’m still relatively new to the cnc plasma world. Im currently having an issue with either the z-axis or THC.
I’m currently cutting 3/16 mild steel, running a Yeswelder Cut65, 70psi, 55amps, 35ipm, cut height is .05. I do a dry run every time before I run the final cut and the z-axis and THC run smooth. but as soon as I start a hot cut the z-axis starts bobbing, while it makes the cuts. even on long straight cuts it does it. all my cuts look like a serrated edge. But my very first cut on the machine after I 1st got it set up produced a very clean crisp cut, but by the end of that 1st cut it started doing what is does now. Any advice or help would be greatly appreciated
