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 ;)

I know that Robert but I always seek for the latest version,lol!
What drivers have you got?
:hysterical:
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?
