Hi all,
I'm currently planning a build with the smallest possible budget. I DO have tons of 80x40 Aluminium extrusion (that take a 12mm thread for bolting together with m12 bolts) that cost me nothing and I have a full set of skate bearings, stainless 19mm pipe and 3/4" aluminium angle I can use. I'm not sure why I went for a fixed gantry build. If you think i should go to sliding gantry please let me know.

May I please have some opinions or advice on this build as it is now? Mostly i'm struggling to come up with a simple design for the z axis that isn't too bulky.

Materials that i'd like to cut are acrylic/perspex and the odd 1.5mm sheet of aluminium for pc case side panels.

Dimensions of the machine are 600mm long, 480mm wide, and whatever high.










Much appreciated
Neal
