Comments sought on new build: A CNC Router for RC Gliders and Planes

[Neale]

I've just about reached the stage on my machine where I have to decide one motor/twin belts or two motors. Sounds like the received wisdom is to go two motors. So, that means buying one more motor, another driver - but the old analogue ones I have at present are obsolete, so that will mean two new digital drivers, and, what's worse, ditching LinuxCNC and having to use Windows/Mach3 to be able to home two motors, and, probably, an external motion controller.

I'm in a similar situation regarding the single vs two steppers, I can either buy another Nema 23 3Nm stepper and driver (but mine are the AM882 so I'd have to source from China or ebay) or a Nema 34 and 240V driver...decided on the Nema 34 for a bit of safety margin...
