I have been looking online for my team for things that could be fun and useful for our 3D printers to print and I have found this mostly 3D printed CNC router. Before we start putting in time and buying the other materials for it I wanted to know if any other team has used this and how it turned out for them. We are planning to go with the primo version. https://docs.v1e.com/mpcnc/intro/
@asid61 I think you’ve worked with these before?
We built one back in 2016 or 2017, and used it for lexan and wood. We could see how helpful a cnc would be in our shop and used this project as justification for buying an avidcnc kit which we have used since 2018.
I think you’ll find you will want a more rigid machine as you start improving your process.

I’ve known teams that make these. While they’re fine for plastic and wood (for a thin definition of fine) it’ll be very very slow on aluminum. If you can find some sponsors to get an Omio later that’s ideal, but for the short term it’s better than not having one for sure. Just try and stick to wood and plastic, and don’t bet on doing anything too accurate in aluminum.

Honestly the MPCNC is not worth building at all. The creator has made some less than good choices on its open source dealings, along with the fact it’s not a great design. Look into the Milo CNC or the PrintNC.
+1 to PrintNC, if the OP can afford it it’s a much better machine than a MPCNC. Milo CNC is too much like a mill to be useful IMO, in FRC you really need the greater work area afforded by a router.
