Thank you. I will correct this.

I think you have it totally wrong, Assuming the diagram is for what I think it is, you need to apply 24v power to pins 1,2,3,4,5,6,7,8 and read the bits from the centre pins.
 

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)

Error getting packages on fresh install on Raspberry Pi 5

Category: QtPyVCP

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 :)
