Got aluminium parts from anodization.

Hi nice small machine, be interesting to see what it does!

something you said caught my guard, is it worth/necessary to anodize your alu parts? I have several parts already machined can I anodize them? or does it change hole sizes and such?

Tidy liitle machine (Andrej knows his stuff!) - are you going to put a front cover plate to protect your X axis? ....that first video you linked to the swarf there is brutal & it will surely prematurely wear out your moving parts.

Honestly, I anodized them because I like the finish. Holes are bigger after anodization, but It is not a big deal since they are bigger for 0.02mm or less. Preventively I protected internal threads with silicone plugs.

It is interesting that bigger parts are darker and thicker anodized. I should ask anodizing guy why.

HankMcSpank: Yes, I am looking for a way to protect moving parts from dust and oil.

I have to make a decision about drivers.

PoLabs PoStep60-256 vs. Leadshine M542 V2.0

What do you guys think?

I would go with Postep as, you could buy the board, the drivers, 3nm motors and the PSU from them, Unfortunately they sold all drives so they said in something like 3 weeks.
