Here is my build after the first crown test a few minutes ago. This is all C size “burly” design parts. I printed all the parts using a heavily upgraded Anet A8 (with enclosure) out of PLA, except for the roller plates. On those I used a thicker design from Thingiverse out of red ABS. The build is 13" square working area, which resulted in a footprint of 24" square. I have it mounted to a 26" square of 3/4" MDF for now. Legs were cut to 3", as I plan on mounting another 3/4" square of MDF on top of the base, as a spoil board. Sometime in the future, I hope to mill aluminum, and possibly even steel if I get skilled enough.
I built the wiring harness myself, as I got fairly competent at crimping pins and building connectors when I modified the 3D printer to use a remote control board. The 4 color LED 22 gauge wiring worked well, as I had 50 meters of that. I also had 10 meters of fiberglass GT2 belt, again from maintenance and upgrade for the 3D printer.
One interesting thing, is that I polished the 3/4" conduit, sourced from a local Lowes store. I first used #1 steel wool lightly to remove any corrosion, then a firm polish with #0000 steel wool. After that, I used metal polish and spun the conduit using a drill with a 3D printed mandrel gadget I found here on this forum. Finally, a last polish using car polish, and they ended up looking like they were chrome plated. It sure made a difference on how smoothly the rollers operated on the conduit.
The only snafu I had in construction was a couple of open connections on the wiring harness where I crimped a DuPont pin a little too hard. I had a bit too much confidence in my wiring skills, and had to back up and retest everything.
At any rate, still a long ways to go here. I plan on making the router tool mount from ABS, sometime this week. Many thanks to V1 Engineering for the extensive resources, that I spent a lot of time consulting.
