Just built my own MPCNC Primo after printing a full set of parts for a friend’s build and getting jealous. Three weeks after starting the first print, I just plotted my first test crown and am excited to start milling! The assembly went much smoother than I expected; kudos to Ryan for an excellent design and to the user community for all of the testing!
I did hit one snag: The tension bolts can’t be properly tensioned if the teeth are biting on the far hole. After disassembling the trucks and filing the holes, the rest went off without a hitch. This would be useful information to include in the assembly instructions, even if it is common knowledge that I was lacking .
The next steps are to print an electronics enclosure, run wiring, mount the spoilboard, and start learning CAM. My project queue includes a wooden wall map, some RC parts, and probably some laser engraving down the road.
Looks great. I dont know that I’d bother with drag chains. I’d just anchor the cables to the sides of the enclosure up high enough that they can’t sag down far enough to interfere with the work.
I started with Marlin but have been much happier after switching to grbl. It has better third-party support and some useful laser features which aren’t available yet in Marlin.
