I’m just starting to build a 2’x2’ MPCnC. I’ve been toying with the idea of building a CnC for a while. I saw this on the Hackaday blog, and it’s just what I have been looking for. The bundle kit is great, and saves me a bunch of time figuring out what I need, and ordering parts from all over the world. I have a PrintrBot Simple, a bunch of filament and a hardware store close by. I couldn’t resist the Buy Now button. My kit is on the way!
I plan to use this mostly for small projects, plastics, plexi-glass, PCB’s, and aluminum things. I’m going small. If I want big, like I decide to carve out a new front door, I can buy more EMT. Once I get this up and running, I would like to try some vinyl cutting, and maybe some laser burning. Maybe screw on a print head if I need to make something bigger than my little printer can handle.
First decision is what color will I use. I have a big roll of blue and roll of white on hand. Looks like it will be blue and white. I started printing a few days ago, and I have a Rigid Coupler, 4 Corner Blocks, one Roller F, and another Roller F in the printer. I checked the sizes of all the parts, and they all can printed on my 100 mm cubed PrintrBot except for the new Rigid Z. I could print the old one, but I’m going to try a cut version. I cut it in the center, and I have two printed pins that will go inside the cut. I will glue these together. If it works, I will share what I have. Outside of that, the rest will be stock.
I’m trying to determine the build area size. I found a few hints, it will be about 13 inches square, and that will be good. So I could get a better understanding of how this all goes together, I put together a virtual model in D123 and I colored the parts to match my plan. This is a big help understanding how it goes together before I start building.
I can also see the legs need to attach to a table to make this rigid. I want this small so I can move it from the basement shop to the garage. I live in Wisconsin, and I have an unheated garage. It’s too cold to do much work out there this time of year except for emergency repairs to the snowmobiles! I like the design of the one in the assembly instructions. I think I will do something similar except without legs. I want to keep the CnC legs short, and if I need more depth, the spoil board could be removed and lowered.
I will post up pictures and updates as I go. Any suggestions are welcome!
