3D Printed & Laser Cut, Lil-CNC Mill ACv2

youmagine

This tiny powerhouse can etch almost any material, including stripping copper off PCBs. It also cuts, drills, and mills soft materials with ease. Although it's not lightning-fast, its compact size and affordable price make it an incredible value. To boost its capabilities, simply upgrade the spindle motor, add side stiffeners, and swap out the all-thread for precision acme rods. The design is highly scalable without requiring new prints; you'll only need to re-cut laser-cut parts and adjust the rod length. Premium quality printed kits are now available for purchase on eBay: Cherry Red: http://www.ebay.com/itm/252043471429 Navy Blue: http://www.ebay.com/itm/252052107810 Black: http://www.ebay.com/itm/252052101200 Neon Green: http://www.ebay.com/itm/252029615065 Watch the mill etch a "Hello World" logo into acrylic: The square border around the Hello World Open Hardware logo is 40x40mm, making it an ideal first etching image for X and Y movement calibration. The text reaches its tallest point at ~4mm tall. A 25-degree, 0.3mm flat tip engraving bit was used. This revised design is fully compatible with the original laser-cut frame from the instructable, although a few small M3 hardware bits have changed in count and length.
