@Discojon: I just have seen you linked my marlin config on Thingiverse.. Time to do an update!
I tried the filament change command a few days ago, there is a bug with the automatic filament change option! The hobbed bolt will eat your filament if you try to use it this way
Therefore I disabled the autochange-option. If you use the change-command, here is how to change the filament:
.) The head will move to the front left edge of the print bed.
.) Remove the filament as usual.
.) Load the new filament, pushing the rest of the old color out of the nozzle by pushing on the filament itself or close the filament release clamp and turn the extruder gear by hand. The stepper is disabled at this step.
.) After purging all old filament, press the LCD knob. The head now moves to the part and continues printing.
Small Changelog to my last release:
- Disabled automatic filament change options (see above)
- Added PETG preheat profile
You may have problems with you settings (PID values and so on) after flashing, thats due to the changed EEPROM layout (added PETG profile). Simply load factory defaults and then choose "Store memory".
