Hi,
Please i need help to solve below issue.
I just started my DIY 3d printer as I’m using skr 1.4 turbo with TMC2209.
I configured as per my machine specs and it’s working fine except extruder retraction it’s pushing the filament forward same extrusion direction.
I check my configuration as I found it fine.
Then I replaced the E0 TMC2209 with DRV8825 and configure E0 motor i found issue solved.
Marlin building needs to set up some parameters. Your problem is called INVERT_E0_DIR in configuration.h
So FALSE or TRUE depending on what you have now.
