Hi, I'm new here and will be needing some help! I still do through hole printed circuit work and a bit of engraving so I'm looking to build my first CNC machine. Electronics isn't a problem for me, but getting the right parts that all work together may be?

I've decided to build a good quality 3-4 axis 3040 machine with 1000 kHz spindle as I'm using 0.3-0.9mm drills and pcb milling needs fine track separation if achievable? I looked carefully at the many Chinese ready builds circa £1k and most came with unacceptable compromises. Many are using 12mm ball screws and bump up the price with large spindle motors and bed size. Pulling apart their specs to see what they are is a minefield of caveat emptor!

I have a bare 3040 gantry frame with decent slides and 16mm ball screws on all axis on the way. It's a lot heavier than the hundreds of machines on Fleabay and can take up to an 80mm spindle motor so I'm optimistic for a starter build?

Thanks in advance as I will be asking about spindles, stepper motors and controllers to start my build.
