I’ve pieced together a PwnCNC kit (110V VFD 1.5Kw) to replace one of the Makitas. I wired up the control cable and power cable to test it out and it throws an ERR02 at me then shuts off. I noticed that the spindle runs super hot after just a few minutes of running, too hot to even touch.
I think I would contact Pwn CNC. I have the water cooled one, and it doesn’t get hot at all.
I contacted them and they told me to check the wiring, which I did.
