With all the latest builds and mods focusing on bigger and badder machines I though I would post about a miniature Z axis slider that I built for a new Laser build called the Junk Box Mini Ox. This slider is based on a modified 2040 v-slot to simulate C-Beam. It uses a unique stepper motor that has a traveling lead screw to move the z axis trolley. The slider. End view. I cut out the center section with a hacksaw, used a drill press and file to make the link piece that ties the plate to the lead screw. Where to cut the 2040 to make the mini C-Beam, remove all the green area.
