Retraction return options on extruder switch.

[NAK3D 0]

Hello,  

Is there an option to reduce the amount of filament return after a nozzle switch? ( i.e. If I retract 12mm when I switch to the other nozzle can I set it to only push 10mm when I switch back?)

Recently I've been having issues with filament jams when switch between extruders.  When I switch back to a nozzle I hear my extruder push back the 12mm I retracted but at the end I will usually hear my extruder skip once like its trying to over extrude.  This has mostly been while using polyalchemy filaments.  I love this filment but it does have a tendency to swell when retracted and I think this is causing the filament not to push as far back in till it get more heat.   I have experimented with manually pulling the filament back a few millimeters between switches and it seems to fix the problem.

 

Thanks
