For me it would boil down to 2 options. Conventional steppers with Good drives like AM/EM or Servos. Wouldn't waste money on Closed loop Steppers.
I certainly don't want to "spoil the ship for a ha'p'orth of tar". Ironically, that's why I was thinking of closed loop. My initial thoughts were to fit Leadshine Nema34 4Nm hybrid servos, but they are only available from China - or at twice the price from the UK. Of course, I'd love to spend hundreds on quality servos, but as a first foray into CNC I need to keep the costs down.
