We expect some visitors in about one hour but I manage to paint the CNC bench today black and the sides where the Y axis extrusions are going to rest... yellow.

I am ready to pull the trigger and order 4x Nema 23 4NM from cnc4you.co.uk , any preferences for a breakout board from there and maybe for drivers?
Or what ever I can order all in once so I wont pay the shipping cost twice, thanks!

Personally I did not like their electronics. Nothing seemed like a bargain :)
Have you thought about motion controllers or/and BOBs?
Was thinking of getting pulleys from there but when I ordered they didnt have htd pulleys. Dont know if they have them now?

Breakout board is in the list, pulleys is a good idea, I just check and see that they have some!
Thanks!

When you measure the depth of nut housing bracket for ordering your screws, remember that the tapering stops 3 to 4 mm before the maximum depth.
I realize that a little bit late but the fix was easy...

You will probably dislike my advice ..
Which is unfortunate, since it is excellent and will help You a lot.

All, absolutely all cnc and mills/routers/machines depend on rigidity.
A common error using linear guides is comparing the max strength of a linear guide to actual work, or load.

A typical old manual lathe, 11-12", has 50 metric tons "strength".
But cutting loads are 50-100 kgf.

The reality is that modern machine tools are about 2% loaded at max vs strength.
