Hey everyone!
I have just upgraded the gear feeder of my UM2 with the one of the UM2+, following the instructions on the website using cura i have changed the firmware of the 3D printer with that of the UM2+. Now the 3D printer has a lot of problems, when i'm printing i have a lot of underextrusion, i'm using a 0.8mm extruder and a PLA filament (form futura - Frosty White) at 210°, when i begin the print i need to modify the flow of the filament from the tune menu on the 3D printer boosting it at 150% but it has a lot of problems when there are a lot of retractions.
Sometimes the problem is bigger and it actually doesn't print, the flow of the material isn't enought and it just leave some plastic spot on the printing plate. I have checked the ptfe and the nozzle, both are fine and the filament dont slip in the gear feeder.
Someone whith the same problem ? suggestions ?
Thx
