                The problem is that you have set your maximum extruder speed to 100mm/min in the M203 command. That is very low and it is making retractions very slow. A more typical value would be 3000 to 6000 mm/min.

                        3 for 1. 1200 here. Getting bumped up.

                        Edit: Huge difference. I have been fighting layer issues and this was the fix. Looked up what the stock printer board was set to (9000) and changed it to that.
