    Jazz mentioned the nema 23 motors... These CNC kits seem cheap... What's the deal with them? Are they any good?

    When it comes to this side of the machine, I have to admit, I'm a bit lost thus far...

    eddy current - you mentioned you spent 1500 on electrical... What was your breakdown? Or shopping list?

    Good motors, but the rest of it is sub-optimal. Those motors need about 75V to run well - see here (and here if you want to see investigate the mechanical equations). Read some more of the build logs on this forum as everything mentioned so far in this thread has already been covered.
