Stepper Driver on The SKR Mini E3 V3

Recommended Posts

I bought a new SKR Mini E3 V3 and installed it in my Ender 3 V1. I had a layer shift problem always in the X axis. After checking all mechanical possibilities I change the mother board. I had a spare new board for another project. Long story short the layer shifting went away. I suspect a bad X axis stepper driver. Is this possiable to replace stepper driver on this board? The web site says this is a "UART mode of on-board TMC2209" Stepper driver. Thanks in advance.
