I’m just getting started with my new Lulzbot Mini and have run into an issue where occasionally when it goes through the head cleaning process at the beginning of a print cycle it fully ejects the filament. I’ve noticed when this happens the green wheel (controlling the filament drive) rotates clockwise must faster and greater distance than it does when the issue does not occur.
So far I’ve been printing with MatterControl Touch printer controller and two different PLA’s. Interestingly I’ve seen this occur only with one of the spools which differs only in color but it may be a random occurrence.
I’m currently trying Cura to see if I have different results and so far I haven’t seen this sort of behavior although I’m having other problems with Cura in that the default extruder temperature profile for PLA in my opinion is way too high (220C) which is causing parts to be too soft while printing.
Does the Lulzbot Mini have firmware that is in control of the head cleaning and bed levelling process or are these processes controlled completely (and thus can differ) with different printer controller software?
