Extrude/Retract "Flaw"?

I’ve just ran into an “issue” when changing filament I “accidentally” pressed extrude HOWEVER my nozzle was in the printing position. I must admit I panicked a bit because I had changed colors and put 75mm as the length to flush out the old. I knew it would back up into my nozzle so I looked for a stop button and there was none. I also tried to move the head up but it wouldn’t let me so I had to flip the power switch.

Shouldn’t the printer raise the head at least 30mm when a manual extract is executed? That could lead to a very clogged head and huge mess!

Am I missing a setting somewhere? If not this should definitely be incorporated into their firmware update.


When doing filament swaps you should always pause the print, then do the change and resume.
