I finally got the GCode written for the 1000amp controller, and etched both sides of a prototype. I am also mostly done with drilling the holes in the PCB, and the heat spreader is all nice and milled super flat and shiny. I sanded it down with 1500 grit sand paper. I'm debating maybe only putting on like 5 - 7 mosfets and 5-7 freewheel mosfets just for the prototype, so it would only be a 500-700amp controller, just for testing purposes. I don't have a motor/coupler/anything that can really test 1000 amps safely. I mostly want to make sure everything turns off and on when it should. There's not a lot of room for error with synchronous rectification.
