It began with creating an extremely rigid axis that incorporates a multi C-Beam Linear Rail system as well as precision lead screws coupled with a tension system for the absolute maximum in performance.

I wanted a CNC machine that was able to do dovetails and other box joints. I also wanted to have it be able to tilt so it would take up less space when I was working on other projects.

Build features include a double c-beam gantry (bonded & mechanically fastened), linear x rails, custom gantry end plates, a custom linear rail & ballscrew Z axis, and custom lead screw tensioning plates. The primary goal was to remove twist from the 1500mm gantry & stiffen the Z axis.

Building the OB Lead 1515 was straight forward. The on-line OpenBuilds assembly videos were extremely clear and easy to follow. Initial build of this machine is with OpenBuilds BlackBox which simplified getting the electronics to work the first time. OpenBuilds staff are friendly and helpful.
