I have just finished upgrading my K8200 printer with the K8203 extruder. I thought all was going well until the first print when I notices the extruder was working backwards. Manually extruding from Repetier causes the filament to retract and retracting causes the filament to extrude. I have confirmed the motor wiring is correct. Is there a setting I need to change in the software / firmware?
Also while I am asking… it said in the instructions when cutting the PTFE sleeve to ensure there was 70cm of tubing left but unless I have missed something it never mentions where this is needed.
Finally, does anyone know what the clearance between the extruder tip and hotbed should be when the Z axis is homed, I am guessing it will be less than the original extruder.
Thanks in advance
