Hi Ultimaker Forum. I have recently bought an Ultimaker 2, but it has some retraction promblems. At times that seems random to me, the extruder on the back of the machine retracts the filament, causing the print to get minor holes in it. If I would print a solid 4 by 4 cm cube it would usually happen about 3 to 6 time per layer!. I have noticed that it usually happens with the white Ultimaker filament. Do any of you know how to solve this?? Any answers will be greatly appreciated.
