Hello Welcome,

You made a nice job of that machine but has well electronics I'd look at using different components to what you used last time. Things have changed in last few years and now the price of Ballscrews and Profiled linear rails have dropped massively so with in reach of DIY budgets.

Regards the Electrics then go with Digital drives not old analog type ie Not M542. Lead shine AM882 are a very good drives at ok money if bought from china. Thou for small machine you could use the slightly lesser spec Dm 556 with 50Vdc Max.

Regards the Motion control then Ethernet is the best. For a small machine that doesn't use slaved axis then IP-M from Cslabs is by far the best. This doesn't need a BOB and comes with spindle speed control. It's very high quality unit with plenty of 24V I/O.

Other alternative is ESS smooth stepper used with a BOB, extra Bobs can be used if more than 5 inputs are required. No speed control unless BOB comes with it and only 5v I/O so more prone to noise.

These are the only two Motion controllers I'll use. I don't ike USB it's too unreliable but If I had to choose then the only one's I'd use are the UC300 or Pokeys 56CNC.
