The project is almost finished and so far everything works acceptable.

The new concept was able to cut 30mm steel and also 2mm stainless steel.

PCBway helped a lot developing the PCBs and I think they deserve a little fan art for their great work.

The total cut took three hours. This is very slow and based on the feedback shown on the UI scope it should be possible to adjust the settings to make it in 1 hour.

The settings file is the same that made the 30mm cut and seems bulletproof. Not a single issue on this cut except one related to the mechanics.

The X axis belt walked off the idler bearings and finally fully popped off the pulley. That happened at the bottom of the W and from there on the X position is a little off. Shit happens.
I'm doing the recordings with a smartphone and had to swap the clips to the PC multiple times. That is why there are cuts.

Next cut will hunt the max speed.

And a look at the G-EDM EVOII boards. In total there are three PCBs. One to switch the sparkpower, one with isolated dual channel Feedback and one controlboard that runs with an ESP32..
