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.
