  1. Hi you may have used shielded trigger cables but not sure from the video. If not run shielded cables where you can also add a torrid ring and loop the trigger wires around it a couple of times might help. Make sure shielded cables are earthed really well. Good luck

  2. I would suggest that you not cut but have made or make the full-length cables because splicing has been shown to cause issues from time to time in these machines. Many people talk about splicing causing response issues and such on the Creality forums.

  3. is there any chance you can do another video as regards the z-axis trigger assembly? Thanks in anticipation. This may be the most straightforward video on building a CNC plasma cutter so far.

  4. That's really impressive, it's like the second industrial revolution that's in the home workshop. You could scan a headgasket and cut out a steel shim? Cut exhaust flanges to delete the cat converter? Turbo flanges. You'll be too busy.
