5 x 10 CNC - Sub $3000 - Wall Mountable

This is the first CNC machine, I've ever built, but I do have a onefinity. So ignore everything Im sure I have done wrong. I started with the goal of Building a wall mountable 5 x 10 CNC machine that I can cut full sheets of materials on. I am getting pretty close to finishing, Although, i still haven't mounted it, and thought, I would post what I have done so far with my build. I will also share a spreadsheet with all the parts, and CAD files for the gantry plates I machined, and the unique T-Shaped 4080 Gantry plates I created that allow this machine to be wall mounted on it's side for more efficient space usage.

Although its taken a year of fiddling, Ive probably only spent an actual months worth of evenings and weekends on it.

MAIN BASE

Ill start with the base. It is 4080 frame with 2040 spreaders. I have the spreaders about every foot, which gives it plenty of rigidity. I connected two sections of 4080 with 2020 connections, and after carefully clamping everything prior to tightening the connectors, the transition between the pieces of c-beam is pretty smooth.

I used some 3d printed brackets to hold a couple additional 2040 pieces to support the cable chains.

GANTRY
The gantry is pretty standard, just two C-Beams and in internal wheel Z-Axis, My Threaded rod, came slightly bent, so I have internal Module 1 Pinon Gears installed, and also a ball screw on order. Not sure if I will go with Rack and Pinon or Ball screw yet, for the X Axis, but I have options. The gantry is mounted to some custom Gantry plates that allowed me to have 8 wheels per side, plus a special T-Shaped gantry plate under the upright c-beam that holds 4 more wheels. This gives me the smoothness and rigidity for a sideways mounted CNC, even though, it is currently shown sitting on the table. I had to go through a few iterations to get this far, and honestly, if I could do it again, I would have done more optimization. Less holes I didn't end up using, and more holes, I had to add manually later. At least i have kept my fusion files up to date.


Y-RAILS
I used internal Module 1 rack and I bought three sizes of Gears. I will update after testing, Not sure which ones will work the best. But the Dual y-motors are mounted on a swiveling spring screw, so they are under some tension. I will be wiring it up this week, so I have no idea how well it works yet, but will keep this section updated. I was optimizing everything i could to make sure I can still fit a full 4x8 sheet on here... Which I can with some room to spare.


The union is so small, and so well joined, that I doubt there will be any noticable effect on cut parts. But I am not doing anything so critical. Of course if 4080 was available in 3000 mm that would be ideal, but overall, for a machine that will make playhouses, and cabinets and just fun projects, I think its going to be fine.


ELECTRONICS
Just using x32 Blackbox and big nema 23 motors. I haven't wired anything up yet... but that is coming this week I hope.
