MPCNC Temporary Hard End-Stops

thingiverse

A set of temporary clamps designed specifically for the center X and Y-conduit on a Mostly Printed CNC machine. These clamps are crafted to fit 1/4-20 bolts and come with a couple of knobs (the recommended knob is available at http://www.thingiverse.com/thing:876395). If you don't have end stops on your machine or if you have a large machine but prefer working in the home corner, these clamps create a local temporary hard end-stop for production jobs and tool changes. Photos demonstrate their use on small CNC machines to establish a temporary zero location, ensuring repeatability between tool changes. A tip is to add a piece of friction tape at the bottom of each clamp for extra holding power without having to tighten them down too hard. These clamps are compatible with MPCNC 525 and now available in various pipe diameters: 23.5 mm, 25.0 mm, and 25.4 mm. If you need additional sizes, please comment below.
