P-cnc

thingiverse

Hi! This is the P-cnc, a CNC machine I designed and built to be compact, affordable, and incredibly powerful. I power it with a Makita RT007C, but I've also included a bracket for a Dewalt router. I mainly use this machine for cutting acrylic and aluminum, but it can easily handle wood. Since the parts have relatively loose tolerances, I recommend printing some test pieces and adjusting the provided CAD file as needed. The P-cnc utilizes Nema 23 motors on all three axes: X and Y are driven by M8 lead screws, while Z is powered by a 12mm lead screw. All three axes ride on 20mm ground shafts with linear bearings, allowing for smooth movement. The machine has a spacious 28x25cm built volume, with an impressive 8cm of Z travel. The P-cnc is housed in a sturdy 20mm thick wooden frame made from OSB. I've included PDF and SVG templates to make it easy to build, and I recommend having the pieces cut to size at your local hardware store if you don't have access to a table saw. The rest of the cuts are not critical and can be made with basic tools. If you're unsure about drilling precise holes, simply drill them 1mm oversized to allow for adjustments later. You'll need approximately 1.5kg of filament, depending on your infill choice. A comprehensive part list is included in the folder, along with all the necessary information to build the machine. Feel free to contact me anytime if you encounter any issues or have questions. I'd love to hear about any modifications you come up with! You can find most of the hardware at Motedis, a great online retailer for European customers. If you need to get in touch, my email address is paul.pro.quentin@gmail.com. Good luck with your project!
