yeah cold extrude through a nozzle doesn’t work very well. :-) if you want to calibrate steps/mm with the nozzle in place. get the nozzle up to temp for the material load filament into the hotend mark 100mm up the filament from a fixed point on top of the hot end, use a marker or score the filament. extrude 100mm of filament nice and slow. measure from the fixed point to the mark previously made on the filament adjust steps as needed

Pre-drilling the holes to recommended size for the tap and using taps with chip clearing design give me great results in ABS, PLA, and Nylon.

You will need a 3mm heat break and 3mm heatsink the rest of the parts are interchangeable.

if the belts are not trimmed they will not let the face plate sit correctly.
