CR-10 Fine Z-Axis Endstop Adjustment by donnyb99

Last crawled date: 3 years, 1 month ago

This is my crude Z-axis endstop adjustment that allows for a fairly fine adjustment of the height of your Z-axis on the CR-10.
BOM:
1x M4 x 5 brass threaded insert
1x M4 x 20
1x M4 hex nut
1x M4 locknut

Use a soldering iron to press the threaded insert into 5mm hole provided for it. Be careful not to get any plastic inside the insert. The inserts I used have a 5mm outer diameter. If yours have a different OD, you will have to adjust the hole accordingly. I made a model using only hex nuts and it was not nearly as stable as this design.


Thread the hex nut all the way up on the M4 screw then thread the M4 through the threaded insert. Thread the locknut on the end of the M4.


Remove the 4 screws holding the plate that carries the X-axis limit switch.

Slide the endstop adjuster over the spacer bolts and screw the plate back on tightly.
You can adjust the height that the Z-axis limit switch will be engaged by loosening or tightening the M4 screw. Ensure to always tighten the hex nut down to the base to ensure the screw doesn't move with the vibrations of the printer.
