Invert E0 stepper direction - Not working
I am testing out the Titan extruder on my Ender 3 Pro with the SKR Mini v2.0 motherboard. This extruder requires the extruder motor to run backwards. I tried 2x today with the custom firmware builder and neither custom firmware actually reverses the motor direction despite the Invert E0 stepper direction being checked in the firmware builder page. Any help would be great! Thanks!
Ok I was able to compile the current production version of Marlin (with SKR Mini v2.0 default config) and set INVERT_E0_DIR to false. I can confirm the motor does indeed run backwards now! Not sure if this is specific to this printer/mobo combo but hopefully that helps. Thanks again for a great service.
Sorry for the delay, I'll track down that build ID and trace it through.
Those options were only recently added - so I'm not ruling out a bug in the builder at this point.
Ok - after some investigation - it seems that the SKR Mini E3 V2.0 board *already* has all but the Z stepper configured to be inverted. This is now displayed properly in the builder interface.
As such, you should now be able to UNCHECK the default for INVERT_E0_DIR and it work correctly.
