    Hi, folks!

    I bought MiniCNC mechanical CNC kit a couple of weeks ago. It is low cost CNC machine designed by "Society of hobby electronics of Slovenia". They made around 150 machines for their members and I am one of them. It's work area is 220mm x 290 mm x 45 mm (ca. A4 paper size).

    Here are two videos of already assembled machine:

    It is time now to assembly my own. I have already powder coated steel parts and prepared aluminium parts for anodization. I have just ordered masking plugs and polyester tape to protect threads and surfaces with close tolerances against effects of anodization.

    I listed some parts bellow which I am planning to install into it.

    1x Kress 1050 FME-1
    1x 5 Axis CNC Breakout Board
    3x Nema 23 Stepper 1.3NMm 2.8A
    3x Leadshine M542 V2.0 Microstepping Driver
    3x CNC-Plus 20mm Jaw Couplings
    3x CNC-Plus Transmission Element For Couplings

    And there are some pics of my non-assembled machine:

    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.

    I wonder if not to grab 4 at that price.

    These are the same drivers. They have been on the market since March or April.
