I'm working on my first dual extruder machine... still... Two things I'm woundering. 1. Is there a way to un-retract at the end of a print? My Dual colour prints always end with one or the other extruder in a retracted position. This is a problem when starting a new print. Especially if I forget it happened and don't manually corect it. 2. Is there a way to have both extruders primed, like the parimiter does for the first head? I can't find anything is Slic3r for it...

G92 E0 0.0 //Sets Extruder 0 position to 0
G92 E1 0.0 //Sets Extruder 1 position to 0
G1 E0 10.0 F1.7 //Moves Extruder 0 10mm at 100mm/min
G1 E1 10.0 F1.7 //Moves Extruder 1 10mm at 100mm/min

I'm not positive right now that is how you call out each extruder, also not sure that the "10.0" correlates to linear movement on the extruder and the feed is 100/60 = 1.6667, that also may be incorrect depending on if feed is mm/s or mm/m.

You could also try

G1 E0 0.0 F1.7
G1 E1 0.0 F1.7

And if the position wasn't reset with a G92 after the retract, they should return to 0.]]> tjb1 General Fri, 11 Apr 2014 13:07:53 -0400 https://reprap.org/forum/read.php?1,338385,338385#msg-338385 https://reprap.org/forum/read.php?1,338385,338385#msg-338385
