So no matter what I try I always get the SPI unable to write Globalscaler error on z1. I wnet to BTT and they sent me a replacement Kraken but I get the same error. I’ve triple checked wiring,replaced the z axis motors and swapped power supplies. I’m at a complete loss as to why this is happening. As always any help/suggestions would be greatly appreciated.

here is my config that works, on your log you have spi speed defined, which I don’t. I didn’t see your sense_resistor defined either.
