Raft doesn't work

Post by AndrewBlack » Wed Mar 21, 2018 12:17 am

Hi everyone,
I have a problem with my Up Box plus.
Every time I try to use the raft for my models, the filament comes out at the beginning on a regular basis, then comes out at intervals, finally stops coming out. I tried different thicknesses and different temperatures but nothing has changed. Currently I use Formfutura Pla that has never given problems. Help me pleaseeeee !!!

Do you hear any clicking from the extruder motor?

Sounds like you might be too close to your board, and the back pressure is jamming the filament. I would suggest pulling it apart and cleaning the teeth of the gear in contact with the filament because with time, they fill up and start slipping. Manually adjust the nozzle height in 0.05 increments away from the board and see if that helps.

i've done this so many times. the problem is that now the printer starts clicking a lot even before the raft. few times later he starts extruding filament. it could be possible that the gear doesn't give the right pressure on the filament?
