The Deiwu I/O does not output PWM,
Rtelligent has one that does.
But as Hakan says an Ethercat stepper driver would be the best solution
eg Rtelligent ECR60 but Leadshine also do one now.

Alright, I assumed you would have one since you have an rpi image builder. But likely it uses a prebuild from Debian that seems to be patched already.

Yes, I built the Pi images for Linuxcnc you find on the downloads page. I shared my repo for the builder on this thread earlier. Bear in mind the pi5 was released just after we released Linuxcnc 2.91 and at the time pi5 support was patchy in the upstream builder. I've since updated the builder and it has been tested on the Pi5 and the shortcomings are reported to be gone.

We actually build the kernel .deb from the official Raspberry pi kernel repo and wrap Debian around it and build a compressed image. The 6.12  kernel should be supported by the builder. You should give it a go. As its cross compiled, building the kernel will be quicker than  it can ever be on a Pi and the kernel as well as an optional img (which we compress) is built.

nah, go 48v if your drives can support it. its the current which matters. You could drive the motors at 72 volt with the right drivers if you wanted and still not break them,

the cheap drives i got are only rated for 42V so i am looking to run them on 36v, this is going to be on the cheap side for builds. i don't do things as pictured by others i just use it for a starting point for planning. i plan on using double shielded wires everywhere with shield drains on everything. i have spent a lot of time reading up on grounding and a lot of it was plasma related for a source. i have seen way too many builds get sideways because of grounding issues

the Nema 23 motors i picked up and dives were only $110 for 4 so nothing very fancy. THCAD is about the cheapest height control on the market, so being able to do that makes me happy

i'm not ready to buy boards from Mesa just yet and the THCAD-300 is out of stock at the moment, and it is a little bit cheaper than the THCAD-2 so with added cost of having to buy extra stuff with shipping on top of that saving $20-$30 makes me lean towards the THCAD-300 just because i am cheap

you put me on the right track.....
I was provided with the vendor ID (0x4321) and product ID / code (0x10C2) by the manufacturer. 
And these values show in the drive through the software also

using the below terminal input
ethercat slaves -v

the product code was 0x00d0   ???

can anyone provide the reasons for this ? please remember the internal drive value is what the manufacturer stated !

i made this change to the .xml and the drive works.
