BTT Pi v1.1 Custom build -Help needed.

Recommended Posts

Motor Rattling, BTT Octopus with TMC 2209

Hoping someone can help, I've been testing this motherboard and have all other motors working, however this one is giving me issues.

It rattles loudly, skips direction as well

The motor: Creality 42-48 Dual Axis (Have tried other motors, and different driver, same issue)
