Hi everybody,

So, this is literally my first post on this wonderful forum, so please be nice to me (English is also not my first language)

This post is intended as a build log (even if it's going to take a year to complete) and to gather experience from you, adjusting my design based on your input.

I am planning on building a small fixed gantry/moving table Mill for milling aluminium with reasonable precision, between 0.01 and 0.005 mm would be ideal if I manage with my low budget.
Work area will be 500x500x150mm, made with aluminium T-slot extrusions (I plan on filling them with sand or epoxy granite later to improve vibration damping).
I have already purchased a complete set of 20 mm square linear rails and ball screws (the chinese set, 1000, 700, 400mm , just like this one). No other purchases were made.
I am planning on using plain nema 23 motors 1,8Nm/254 Oz-in with TB6560 driver.

Gantry is 700mm wide, I plan on using a 80x160mm extrusion. Base is will be 1000mm long, made from 80x80 and 40x160mm extrusions, and 40x80mm traverses.
Z Axis design is still pending. Please let me know what you think.

Thanks in advance!
