Closed, WontfixPublic

Description

Can we add a line in the gcode for the aero tool heads to retract the filament after a print is done, to help avoid some of the clogging issues we are seeing.

How far would we want to retract? Past the heatbreak or all the way out?
What if a user just wants to restart? If we back up and the filament cant get back into the heatbreak could make matters worse maybe?

We have a retract before the tool head moves to parking position at the end of the print. We re-prime the Aerostruders and V3 Dual extruders to prevent a die swell jam that was reported early on. See T1724 for more details.
