I am building a dual-extruder printer and have used a BTT SKR 1.4 Turbo board with TMC2209 drivers running Marlin 2.0 Firmware.
I have all three axis working as expected and the hotends heat up and have show appropriate measurement and control. The only item I can’t figure out is the extruders. Neither will move when issued commands. I have checked the Motors and wires running to the motors and confirmed they are all function and working.
Any ideas why three of the five axis will run, but no matter what I try the extruders fail to enable and move? I am stumped!
