New start

You must go with DC so I can copy the plans and make my DC power supply!

If I had a drive with the option of AC input, I would go with that. It will have an appropriate internal rectifier/capacitor setup, and actually the capacitors do not need to be that big. You use bigger capacitors when the PSU is feeding multiple drives as you are smoothing with a bigger current demand, and it also provides a bit more isolation between drives so demand from one will not affect the others. Stepper drivers really do not need a very smooth supply voltage anyway - because of the way they work, they are pretty tolerant of supply voltage ripple.

All good points ;)

Nick you have loads of ppl to copy already :D

Neale, you might just have persuaded me ;)

Hahaha :D
You know to look for the latest stable version... right?

Im a cheap bastard (probably on the stupid side)
Got myself som 2dm860 chinastyle drivers..
They accept 80vac or 110vdc

Will se how they work ;)

Whatever works for you I was going to use an arduino and polou drivers originally glad I didn't lol. But they were cheap so I might well use them for laser cutter.

Given the price of a PP BOB the arduino really doesn't make sense and it's actually more expensive assuming you can get a PC for free for this task which I'm sure most of us can.

Just re-read the whole thread and I may have missed it again, but did not see how do you connect the two extrusions to each other? What is their size BTW?
