Help needed with STEPPER MOTOR choices.

[The Gresley Luthier]

Hi, I first posted this 4 days ago with no replies yet, maybe I got the wrong Forum, here it is again..

I am building my own CNC wood router, for cutting and shaping guitar bodies and other wooden parts, I have limited space in my man cave, so I have gone with an initial design with a work area of 800mm x 600mm using 16mm Linear Rails. My problem is I cannot decide if I should use NEMA 17's or NEMA 23 's, Stepper Motors, mainly because NEMA 23's appear a lot more expensive than NEMA 17's (I am retired on a Pension) The hardest wood I will be cutting will probably be Alder & Basswood for the bodies, I sometimes use Mahogany, Maple or Rosewood for Guitar Fingerboards, this usually involves very little heavy work

All advice would be gratefully appreciated, I hope I have provided enough information.

Regards.

Ray

If you don't want to be disappointed later I would go with the NEMA 23s.
I built a machine for the same purpose but went for 900 x 600 due to similar lack of space.
My build log is here if you are interested, https://www.mycncuk.com/threads/6565...9344#post49344

Many thanks, that's what I initially thought, I will just have to save up a bit more money.
