Hi All,

Hoping someone can review my config.

I am trying to replace my DVR8825 on E0 with a Bigfoot BSD2660 driver.

The extruder just seems to lock in place when I ask it to extrude. I've confirmed both the stepper driver and motor/wiring are fully functioning on another axis. Any insight would be very welcome and appreciated!
