I've recently built the Prusa i3 from RepRapGuru and it was working fine (with minor hiccups), but decided to change the hotend. The new hotend was not what I anticipated so the original hotend is back on.Unfortunately, I disassembled the hotend/extruder when I initially removed it. My problem was with the reassembly. It seemed pretty straightforward, but now the extruder will take the filament extrude a little and then the filament retracts and won't go back into the hotend. The stepper is continuing to move correctly, but it seems that the extruder is letting go. I suppose I need a diagram to reassemble the hotend correctly. Any help would be appreciated.
