Dual Extruders

Hey guys, working with my Makergear M2 on dual extruders and I'm having some trouble with retraction.

I want to retract a long distance when the tool goes idle (so it doesn't ooze everywhere). I'm sort of unsure where to do this. I added a retract into "Cool & Retire Old Ext" and then assumed I'd need to add the reverse of that retract in "Select New Ext & Warm", but that caused a problem on the initial tool that wasn't already retracted.

I can't remember what I tried next, but I remember conflicting with the prime for lines too...like my extrude (to compensate for the retract) and then the prime was too much.

Any ideas where I'd do this?

Thanks,

Lon

I would set it up so at program start all extruders are pulled back the distance I wanted retracted. So maybe at extruder deselect/program end they end up retracted, so at program start/tool selection they are already retracted.

*this would also work if you have a hotend wiper/purge at tool select.
