Extruder retracts filament when canceling
January 02, 2017 06:08AM
Since bumping from dc42's firmware 1.09 to 1.17 my printer now retracts the same quantity of filament as has been printed if I pause and cancel the print. Why is that?

This is mentioned in the upgrade notes at [github.com].

Thank you. Another problem, which I can't seem to find a solution for in the upgrade notes, is that I need to re-home after a print is done.

That's because you have a command to turn the motors off in your slicer end gcode. RRF assumes that the motors can'r be relied on to hold position when they are disabled.
