Creality Sermoon D1 threaded adjustable Z Limit System
byShayne the bald Squatch
I wanted an adjustable Z Limit with a threaded adjuster, so came up with this system. Reuses the original switch and it's harness, NO HOLES DRILLED, and mounts to existing bolt holes and T-Slot railing. It's not super convenient to get to, but it's not horrible, and once it's locked in place, it's not going to need much access anyway. Additional Parts Needed:
- 30-35mm M5 bolt, must be fully threaded
- M5 nut x2
- M5x15 bolts x 2
- M5 T-slot nuts
- M4x15 bolts x 2
The adjust block has a 4.9mm hole where the adjuster bolt goes in, that's intentionally tight fitting. Work it back and forth a few times if you want to loosen it up, or run a tap thru it first. I use a jam nut on top to make 110% sure it stays put. There is a jam nut under the switch pad for the same reason. The pad helps keep the factory limit switch arm from scraping or snagging. Mine had enough crunchy noises for me to investigate and decided the metal lever on the metal bolt was NOT a good idea.
The Switch Mount bolts on using the 2 existing bolt holes for the left side cover (as facing the doors). It fits over the existing bracket, just need 2 longer bolts.
