@Max Favre I'm so glad that your thinking of using Trinamics. I was also thinking the same when I first saw your design. Do you follow Marco Reps on youtube? https://www.youtube.com/watch?v=ZzO9skEYqwY I wonder if limit switches are necessary with the trinamics current sense back shown in his video here.
Do you think an HDMI cable could work? OR DVI? I have been reading that in premium HDMI cables that the strands are paired and sub wrapped by AL as pairs then externally wrapped by braided steel or AL. Furthermore premiums can have 26 or 28 AWG which might be able to handle the current. 2 amps roughly at 26 awg. https://www.powerstream.com/Wire_Size.htm I haven't dived into the typical current draw for this arm design using the motors from the stepper online kit, so take that with a grain of salt.
Also I am a big fan of raspberry pi. Any interest in model 3b+?
Hi.... totally dismantled the CNCCS prototype. Many of the parts are the same as used on the current builds, so I decided to do a new build from scratch so that I could utilize these parts.
On this build I am going to go with aluminum on the plate material. My goal is to do this without any special machining gear. IE pretty much using a drill press.
Before I get started I wanted to show you my layout since you will see much of it in the background of this build.

DVI won't work neither. They are similar to VGA with digital signal added. Some pins are common ground, analog signals use coaxial wire,etc.
HDMI looks like the same with common grounds

1) Sorry, what is the "CNCCS prototype"
2) If you can use as much aluminium plate I think that is a great goal.
3) Can we see the layout?
