Assembly and Installation
Step 1: Insert Magnets
Insert the 6 magnets from both sides so that they are flush with the printed part.
Pay attention to the orientation of the magnets! Make sure all magnets are oriented the same way and orient the magnets according to your preferences. I personally have the north pole towards the extruder and the south pole towards the spool across all my printers.
To push the magnets in it may be helpful to use a bench vise or a pair of parallel jaw wrench pliers (e.g. Knipex 86 03 180) or something similar.
Step 2: Insert Mounting Hardware
Push the M6x12mm screws through the holes and loosely install the T-nuts.
Step 3: Installation
Install the holder on the side of the 3060 Z-extrusion.
Step 4: Test
Attach PTFE Joiners with some PTFE tubing and test the filament path.
