Remix Of Nikodem Bartnik Dremel CNC Z-Carriage for Mini V-Wheel Support

thingiverse

Remix of this remix: https://www.thingiverse.com/thing:3765468 Designed my own Z-Carriage to let me add mini-V-wheels to use the included 2040 extrusion as extra torsional support, increase rigidity and have a more stable spindle/bit. I also added a rear 'support' gantry plate for the mini-V-wheels. I included the original designers (HyperRC) two X-Carriage designs as reference since this design is based on, and requires his X-Carriages. Big thanks to him for his great idea. He has 2 versions, one using M5 and the other using M6 bolts depending on your extrusion spec. Parts needed for mini-V-Wheel runner: (This excludes the 2040 V-Slot profile, and the bolts needed to mount that, suffice it to say that the 2040 extrusion should be cut to the same length as the other cross-struts used on the base of the DIY Dremel CNC - X dimension) 4 mini-V-wheel kits... (They should include standard 6mm spacers, and 2 1.4mm washers each) 4 Eccentric Nuts. (6mm with 7mm 'guide' lug) 4 M5 bolts by 40mm long (Button-head or Hex-key socket, either will work) Assembly: The top two wheels are assembled using a 6mm spacer, washer, wheel (with bearings), second washer and second 6mm spacer. The bottom two wheels are assembled using an eccentric nut, washer, wheel (with bearings), second washer and a second eccentric nut. Then through the backing plate, and secured using nylock nuts.
