Mechanical Assembly

Threadlocker

These machines vibrate intensely when running and fasteners are bound to back out. Don’t be afraid to add a little bit of medium-strength threadlocker to your central screw to avoid this problem. Threadlocker should not be used on the self-tapping screws as the chemicals in threadlocker may damage the ABS and cause it to weaken.

Are you building an LDO kit?

LDO has written a fantastic supplementary guide for the wiring included with their kit, which is pre-cut, pre-crimped, and pre-soldered! If you're building an LDO kit then check out their guide here!

Plug the toolsetter into the Z_MAX endstop connector. Note that your wire colours may be different than those shown in the images.
