After spending a lot of time building, improving and using 3D printers, I finally wanted to get into the other end of manufacturing: subtractive manufacturing. So I needed a CNC Router and a printable one came in very handy. Although I did some modifications to the original version, the MPCNC itself is a beautiful and thoughtfully designed machine. Big thanks to Ryan for making this possible!
Here are some facts about my build:
- 600x300mm work area
- roughly 50mm z-travel
- 25mm stainless steel tube (2mm thick)
- 3D printed parts with four perimeters and 60% infill (all PLA, except spindle mounting)
- 15mm GT2 belt, double belt setup
- cable chains on all axis (the one of the middle assembly is missing right now)
- new cables for the stepper motors (flexible and shielded)
- RAMPS 1.5 controller board
If you haven’t heard of using two belts before: The lower belt acts like a track, where the upper belt rides in. By using two idler bearings which press the upper belt into the lower belt, you can create two anchor points right next to the carriage instead of having the belt fixed at both ends of the machine. Therefore you effectively have a much shorter belt and hopefully less belt stretch aswell.
My spindle is going to arrive in the next days, can’t wait to finally make some chips ;).
