Hello, im looking to build my first CNC, so i have been lurking around here for a while now looking and reading up. I recently met the builder of SweetDream at the engineering show, who gave me some great pointers and as a result i have altered my design more.

So im looking at building it 500mm x 400mm with 100mm Z axis. Im looking at using SRB20 supported rails and 1604 ballscrews throughout the design. I still need to do more drawing as you can tell ie the rest of the frame below the y axis rails, but if anyone can spot anything that would be great.


The gantry side plates and main spindle plate will be from 6082 20mm aluminium, and the box that wraps round the rails on the x axis will be from 6082 10mm aluminium. The gantry side plates will be joined to the y axis bearing blocks via 60x60mm x 4mm thick aluminium box and inside that i have mounted the ball nut into an aluminium block which is then joined to the aluminium box.
