Hi all, i'm a long time reader, first time poster. I have experience in CNC and own an A3 sized desktop one and want to upgrade with a new home build. Basically i just want to cut mdf and ply with it, speed and really tight accuracy are not really that important and I have yet to calculate my motor requirements except that I'm going nema 23 for size.
I just wanted maybe a more experienced builder or anyone in the know really to have a look at my design and see if there is anything obvious that might hold my design back before I commit to ordering the parts.
The goal was to create it as cheap as possible but try and keep rigidity. I've used 16mm multi-start trapezoidal lead screws on x, y and z. Fully supported 16mm rails on x and y and 16mm round rail on z. My main concern is the lead screws on x sagging?? The machine is 1500mm x 1000mm at the rails.
Any advise would be greatly appreciated. Thanks
