Mk5 to Mk 6 3mm question
I'm trying to get the Mk5 to Mk6 upgrade done today and I'm at the last step of mechanical construction. Two questions:
1.Is the bearing that I used with the DC motor still necessary? It appears from the pics here:

that it's not sitting in the opening in the in front of the filament drive housing.
2. I'm having a bear of a time seeing down into the filament opening to determine if I have the filament drive gear properly positioned, as is shown in the pic in the instructions. Is there any trick to this? I've tried various lighting and magnifying glasses. What am I missing?
