Hello Everyone

[Robrant]

Thanks Irving,

I'll order some TR10x2D today.

For rails I like the idea of bearings and angled alloy running on some steel bars I have (from old printers).

I want to get the steppers and drivers hooked up to the PC and get my head around that first.
The stepper motors are what I'm stuck on, some are 3v, 5v or even 24v and I don't know how to set this on the driver.
Was looking at these:

Or even something like this:

Or am I way off?

PCB Milling is something I'd like to do, nothing too strenuous though.
I'll certainly keep a log.

All the best
Regards
Rob

Ignore stepper voltage, what matters is phase current. The stepper driver can be set to provide a constant current to the coils. For the sort of size you are refering to, with the frictional loads you need to be looking at motors with 1 - 1.5Nm of holding torque. The size 16's you list are 0.7Nm which is probably marginal. Size 23 motors, 1.8deg step (200steps/rev) are what you need, the board you have will drive up to 2.5A bipolar parallel wired motors (8 or 4 wire, not 6-wire). A typical motor would be this

Thanks again Irving,

It's a big learning curve for me, just got my head around Mach3 last night using a little stepper, it got too hot to hold so that'll be the phase current.

I'll watch those motors or get something more appropriate as you suggest.
