DIY Build of Aluminium CNC Wood Router without Workshop & Tools

[WandrinAndy]

Following the change in gantry design it made sense to rationalise some material used, as the minimum profile length from Aluminium Warehouse seems to be 2500.

Have also tweaked and simplified my overall design... and am sure there is still more tweaking to come... Gawd I can go off on a tangent and over-complicate things unnecessarily!

Have corrected the collision-ing at the extremities of the X-axis travel in the virtual world... Can now easily slide the gantry along it's entire length of travel within SketchUp with a few mm to spare!

From pics I've seen I'm guessing that the drive shaft of the Nema23 motor is too short to accommodate a pulley if the motor is mounted with the shaft going through 10mm plate... Please shout if this isn't the case... So still have to design a mount to solve this.

I think that so far virtually everything is within my limited capabilities and my limited workshop/tools facilities, particularly if I can get Aluminium Warehouse to cut the aluminium profile to the required lengths. The one exception is that I am looking at ballscrew housing mounts (purple) on the X-axis that also serve to brace the gantry-end angle profile.

Have just started on the Y and Z carriages... Will probably use Zapp's Hiwin HGR20R profile-rails (800mm and 400mm) and HGH20CAZA medium-preload four-row bearing blocks. Pretty sure it will require machining to keep
the Z-Axis really close to the Y-Axis, so when I get there I'm hoping that someone on the forum offers machining as a service and would have the time to build these for me?
