Engines hum and heat up a lot with Kraken and RatOS2.1
I have a similar problem, also a new BTT Kraken on a Vcore 3.1 and 48V and Ratos 2.1. I switched from a Duet3d HC6 with RRF because i wanted the Beacon. Z-motors seem to work, although with a sound i didnt have before. X and Y moved a couple of times and it homed. But now when i try to move X or Y, Klipper shuts down and i get an error message: "tmc 'stepper_x' reports error: gstat: 00000004 uv_cp=1(undervoltage!)". I have checked my cables and connectors, also reverted back to 24V for the drivers, no luck. I noticed that the 4 first TMC2160-drivers on the Kraken have a sense_resistor value of 0.022 and the other 4 drivers 0.075. This is probably part of the problem. I have now measured the resistance in my X and Y steppers and it is about 1,5 ohms in one winding and 0.5 in the other, so i will need new steppers... I will try again with new ones, but it seems that the config for the BTT Kraken isn't correct in Klipper. In the printer.conf it says that the stepper drivers are 5160 and not 2160, but this is maybe just a copy/paste thing? I have only just started with Klipper, coming from RRF, and it still a bit confusing...
