@thedragonlord Getting the "lid" holding the circuit board and the main part holding the mechanical parts to seat well is the trick. There are little pins that it sits on. It should be on a very slight tilt/angle with the magnet side higher before inserting the screws. This is a very small gap and may get messed up by the filament just not being precise enough, I did manage to get it working with PETG and some razor knife trimming. However I still wasn't happy with it. I re-did it in resin when I got access to a printer. Just be patient with it.
