    Just another extrusion/Aluminium CNC

    Hi. I'm working on this build for about 2 years now and jsut wanted to share some pictures of the progress.

    The Framesize is 1000mm x 800mm. It is a direct driven dual drive gantry design inspired by the famous Gabriels build.

    It uses 25mm linear rails on all Axis and 1605 ballscrews on X & Z and 2005 on Y. I wanted 10mm pitch at first but ordered 5mm pitch... and for now can live with it.

    Motors are high torque Nema23 steppers. In the future I update to 400W Servos.

    Everything was done with simple tools like a drill stand and a sliding mite saw.


    This is how it will look at the end:

    5mm pitch Ballscrews are good for Zaxes but not X and Y you want at least 10mm Pitch for X and Y Axes

    If you do use the servos it won't be to bad for speed, but the steppers would be very slow

    I received the large Profiles yesterday and mounted them. Next step is aligning and squaring everything which feels like it will be much butthurt.

    @fretman_2 thanks. I'm very happy with it too.

    PS: Some pictures of the aligning process will follow these days.

    Re: Just another extrusion/Aluminium CNC

    Today I started aligning some parts.

    The left Y Profile was clamped in position with 1-2-3 blocks and attached to the bottomframe.

    To flush both Y profiles I clamped them between the motormounts.




    To get a little pressure from above I improved a bit:




    With everything clamped that way I tightend the Anglebrackets of the secondary Y Profile.

    Next step was aligning the Linearrail of the left Y Axis which was pretty simple. Just mounted a dial gage to the slide and drove along the screws. A little pressure here, some more pressure there to get it near zero.








    Last step was inserting the fastener caps. After inserting them I used a razorblade plane to cut away the overhang.

    What kind of couplings are you using for the nema 24's and the threaded rods?
