Super hot LDO motors #371

Closed fuganater closed 4 years ago

fuganater commented 4 years ago

I recently upgraded my custom i3 to a full set of LDO motors and they are getting up to 80C while printing. I've been asking in Discords, the BTT Facebook group and Twitter and no one seems to know what the cause is.

I'm using a SKR 1.3 with BTT TMC2209 V1.2 drivers in UART mode and Sensorless homing on X and Y. Attached is my config.h and config_adv.h.
