The machine is currently controlled by the Openbuilds Blackbox system and the linear rails are 20x40mm VSlot extruded aluminum with 3d printed mounts. The 3d printed mounts are filled with epoxy.

Yes that's right, off the shelf aluminum extrusion rails and delrin wheels.

Exactly right, and also standing boards and panels on edge for joinery etc.

Yep. It's all layered 3/4" Birch Plywood.

​@@TyMakesStuff, painted yellow? It looks like solid piece of cast iron!!!!

It can machine aluminum in small amounts. Certainly enough for small prototype work. But as it is with nearly all of these non-professional machines the lack of what I would call extreme rigidity causes tools to age rapidly.

@@TyMakesStuff may I ask u to share stl`s for your custom aluminum profiles stands, and belt tights?

The Y axis is belt drive because the machine has a 9 foot run in the Y direction and I could not find/afford lead screws or ball screws that large.

Yes, great work. Looks really beautiful. i mean that left and right sides of Y has different mounts and mechanisms in total. Can u share technical details why did u make it this way? @@TyMakesStuff

@user-do6co4fi7r Oh ok I understand the question now thank you! So this design has evolved a lot since I first started building the machine. Originally, the plan was to make a router that would travel along the entire length of any wall mounted workbench without being in the way. So the reason for the front edge (camera left in the video) of the gantry sitting lower than the back edge is to keep everything below flush. This allows me to use the workbench when the gantry is stowed away. Right now the spoilboard is a bit thinner than I anticipated so the Y2 belt sits just above flush, but I am still able to slide heavy sheet goods onto the workbench without the drive system getting in the way. If you watch my other video showing the first prototype you will see the y belt resting well below flush at the forward edge. (Edited to add the following) Another initial consideration was modularity. The router system is fastened to the pre-existing workbench, rather than being fully integrated into it if that makes sense. Because of this it is necessary to establish a reference datum to square the machine relative to itself. In this setup the front rail is fixed and the back rail slides free in the XY plane until square is found using the gantry as a spacing jig. Then the back rail is screwed down.

​@@TyMakesStuff thanks for your time. are u calling back rail the upper rail (right side) from camera view?

Yes that's right

I did not manufacture the entire machine. Many of the parts were purchased online. Fasteners, linear rails, aluminum extrusion, stepper motors, drag chains etc. All off-the-shelf. But I did manufacture a lot of it. The gantry was designed by me and cut out of sheet stock plywood by an older iteration of this machine (which was itself built with traditional wood shop tools and a 3d printer). All of the structural hardware is 3d printed and designed by me. The spindle mount, bearing plates, and belt tensioners were also produced this way, and so on.
