Thank you. I will correct this.

There is only one center pin.

Oh, I forgot the cost of the variact which is likely ~$50-60.

Can't forget the little extra's.

Thanks for the info!

I didn't mention it but I was thinking of using a Variact so I could adjust output voltage and use 110/220 if need be.

Since you have experience with this specific driver - What do you think?

Is is worth the extra $20x4? (3 axis dual y)

Thank you rodw, thats exactly what I was looking for!

We don't use it but I have in the past.. Debian do offer an image for the pi
raspi.debian.net//
Its very minimal (command line only), You can build it up to run linuxcnc. Its interesting to read their FAQ page for reasons why they don't include configuration packages and why they don't include a build for the Pi5

Our approach to compile the Pi kernel instead of using Debian's solves some issues but we follow their minimalisitc approach. be thankful we provide menu-config

TL:DR

Oh, and I forgot to say don't go to the maximum voltage. look for something in the 50-72 volt range so you don't push to the limits.

I used one of these 60v AC toroids for my  Rtelligent ECT86 drives

I had a couple of these custom  made for another project.

Toroids are generally preferred for steppers.
Often a toridal power supply for steppers will include a DC recifier.
This is unecessary if your drives accept AC and it also simplifies the wiring.

I'm not sure of the internal circuitry of the drives, but somewhere the voltage must be converted to DC to operate the steppers
converting AC to DC steps up by a factor of approximately 1.4 so this 60 volt gives around 84 volts.

If you don’t live in a hot climate or intend running it in a hot environment it should be fine.
I’m basing this on my experience with using an industrial pc 24/7 as a router/firewall.
I think the J1900 were popular a few years ago.
