My DIY CNC - base frame soon ready. Have to test one more time that all is aligned ok. Base frame 50-60 kg - hope it is going to work ok.

A simple test, seems to be ok I think

I still find it a bit hard to select the correct controller/driver/stepper combination for my DIY CNC.

  • Based on USB, Ethernet or LPT? (I think Ethernet or LPT)?
  • Should I select controller that supports Mach3 or use other software…?
  • I use Fusion 360 for my designs - there is CAM support, but I have not tested it, do not know how it is compared to other software…

I`ll spend some time while working with the hardware part and try to find a setup that is ok.

A lot to learn I guess, but that is some of the fun with projects like this (Learning by doing) :slight_smile:

1610 ballscrew for the x-axis arrived today. Have to start working on the gantry parts.

What kind of couplings should I use?
Flexible Jaw Coupling like this:

or like this?

Other/better alternatives?

I consider a setup something like this:

  • Use belt/pulley coupling 1:1, 1:2 or 1:4
  • Nema 23 with medium Oz (300+) with low inductance
    Gecko 540 (solid and safe)
  • PSU with 48V

I need some more time before I decide what controller… to use
