  1. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    One small update on this project. I have changed my mind and bought a TIG welder.
    I will first build a workbench and a small welding table to somehow improve my welding skills and then will move...
  2. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    So I did some simulations (I have Fusion360) and for a 100Kg down force in the middle of the bed (in the first configuration, with the carriages at the edge of the bed) I get only a 5 micron...
  3. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    Yes, good point on that. I changed the two steel tubes from 80x80x5 to 140x80x5 so this gives me around 60mm on each side to move the rails inwards. So now I have around 120-260-120 mm between the...
  4. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    Been working on finishing the CAD design (well, not quite finished, the steppers are missing). I made some extra support for the gantry legs, I don't know if this will improve rigidity much, but like...
  5. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    awerby: I don't think that I will easily find those ground steel tubes in my area, but your advice made me rethink my design. I have a supplier of heavy duty steel tubes in walking distance from my...
  6. Re: Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    Yes, you are absolutely right, I don't know what I was thinking. 5-10 Microns accuracy .. I wanted to rival a 300k machine :)
    Back with our feet on the ground, If I will be able to get 0.05-0.08...
  7. Fixed Gantry CNC Mill for cutting Aluminium and softer materials

    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...
