This is a modification kit to provide anti backlash nuts for your Mill One. This kit provides a drop in replacement to standard ACME nuts on the Mill One V1 and V2 machines, and greatly increases the precision of your machine by removing backlash using a spring loaded dual nut system. This upgrade is recommended for users who use their Mill One for high precision applications such as PCB milling and model making.
