Filament retraction problem with Ultimaker Prints Adam #599
After completing a print, the printer is supposed to reverse the filament slightly so that it doesn't block the print head. It seems to be reversing too far or not moving forwards enough at the beginning of the next print.
Temporary solution is to to remove the clip from the top of the print head, move the filament forwards using the controls on the front of the printer, cut the end of the filament on the diagonal, put the filament in place manually so that it starts extruding, then replace the clip.
