Rewriting the Code to match the G-EDM EVO Cube

good work 👍🏻👍🏻

Thanks. Is not easy to write the control logic but there will be a new video soon. Seems the magic is to not try to prevent shorts but to let it short controlled without dropping the voltage. The average Amps in the video cut was 0.3A. Currently burning at constant 0.6A and allow short circuits up to 2A for a given number of microseconds without dropping the voltage. Short circuit with a voltage drop seem to be the root issue I had. Fixed it now. Don't fight the shorts, fight the forward motion.

@@G-EDM I am not an expert in electronics, but yes, the control of the power that the wire can support without burning that is the difficult thing to achieve, it is something that not everyone understands, the ‘easy’ is to build a generator that gives many amps.

@@tessenCNC Lucky I did not have to go that deep into electronics. Current control is done with the DPM buck converter that works well. It can be set to a current that the wire can take and for a given time range the wire can also take a much higher current. Problem with the DPM is only that once a short circuit happens the voltage drops and that drop makes a short circuit worse. Just figured that out today and will add some new logic to the code.
