Extreme Retracts!

[ZionPhil]

MatterSlice has been great for me, but recently on the last 2 prints it has been generating some EXTREME RETRACTS. On the first print, it was doing some extremely fast retracts, like as fast as the stepper motor can turn and by a distance of at least 80mm! The 2nd print with a completely different STL, did such a great retract that it backed the filament completely out of the nozzle and past the EZStruder knurl nut ( I am Air Struding that's only a distance of about 100mm or more).

As anyone had this experience? MatterSlice Retract settings below:

Look at the generated GCode, it should be doing a G92 E0 between layers.
The default for the firmware is absolute E and if it's not reset it can wrap and cause the issue you are describing.

Did you fix your issue? My printer started doing this randomly after adding some led lights and fans. The code looks good so I think it is caused by wire noise going to the stepper motor. I tried tying back the 12 v power lines away from stepper motor cables, and it got better. I still hear the extreme retracts (1 or 2) during my printing.

I ended up moving my side fan to the same side I get the 12v from and without having the power cable going across the back of the controller card, my quick retraction have all stopped.
