[ENHANCEMENT] Stop and backout stuck filament when manual change during a job #4288

Open TraylorHead opened 1 week ago

TraylorHead commented 1 week ago

Printer model

MK4

Describe the enhancement

While printing in single filament mode and inserting a Color change at a layer the filament jammed when being feed in. There was no way to stop it other than pressing the reset button and loosing the job.

Firmware - 6.1.3+7898

Expected functionality

If jammed (grinding noise), maybe use a double click of the selection knob to stop the feed and allow you to use the knob to move the filament motor in either direction to help remove the jam. Once cleared, a single press would resume the filament loading stage and complete the filament change.
