For reasons not yet known to mankind, the Plus 4 eats up the original grommets pretty fast. I didn't want to leave the area open, so I designed and printed new ones. Printed from TPU, good luck eating these up, +4!
PRINTING INSTRUCTIONS:
Print solid, Arachne wall generator, precise wall recommended, no supports, no brim.
INSTALLING:
- Bring the bed up, Z height less than 50mm.
- Unscrew the two allen screws that attach the lead screw bracket onto the printer frame.
- Lift the printer frame up while you carefully press the bracket down. You might need to use some force to separate them.
- Turn the bracket 180° around the lead screw so you can lift the bracket off. Make sure the bearings and grommets stay in place!
- Put the printed grommet on the lead screw. Confirm that it slides up and down the lead screw with minimal effort. If not, use a sharp knife to get rid of any burrs on the inner surface.
- Press the grommet in place. Make sure it sits flat.
- Install the bracket back on. Make sure not to twist the bracket while tightening the screws.
- (Install and) run SCREWS_TILT_CALCULATE, and tram the bed as needed. (Stock Platform Reset can do a similar job.)
- Run Auto Bed Leveling.
