Press Knob before changing filament #70

Open dimensionarg opened 1 year ago

dimensionarg commented 1 year ago

Hi!

I have a small MK3 and MINI Farm, and i saw a diference when changing filaments: MK3 ask you to press knob before taking the filament out, but the MINI doesn't. This is a problem because, if you are not near to the printer and you dont take the filament out, the tip (that is still malleable because it cames from the hotend/nozzle) starts to cold down but the gravity make the tip to bend/fold down, so it forms like a "hook", and this makes the filament to get stuck. If you pull with some sthengh the filament gets out, but some part of the filament breaks and a small piece starts to accumulate in the extruder and this bring other problems.

Can i fix this from the gcode? or will need to wait from next firmware update (only if you think this is a problem)

Thanks!
