This kit provides a drop-in replacement to standard ACME nuts on the Mill One V1, V2, and V3 machines. Using a spring-loaded, dual-nut system removes backlash due to wear in the machine’s linear motion system and ensures long-term machine precision. This upgrade is recommended for users who use their Mill One for high precision applications.
Notes on assembly:
- Both halves of the nut interlock with each other. Ensure that both halves sit together as shown in the photo (spring removed to make it easier to see).
- It may be easier to install if you remove the lead screw first and thread it into the anti-backlash nut.
- The spring can sometimes shoot the back part out!
- The photo below shows a correctly installed anti-backlash nut.
