I was planning on doing the same thing, I 3D printed a panel to hold them with plans to mount the 3D panel on the door. Looked great. The fun began when it came to wiring them. I only have one 24vdc power supply and it’s dedicated to the Acorn board. Everything else is 48 vdc and 220 vac. Those meters are limited to max 36 volts for power. The instructions are as good as if you didn’t have any to start with. I smoked one before I read that on a competitor’s instructions. It would have been cool to look at but I scraped the idea. I may come back to it but for now I’ll look for the shop lights to dim if there’s a problem. Totally enjoying you videos of the progress.
Yea, the ones I have say 30 volts max to run the meter. The meters will measure 100 volts DC though, or so they say; and 10 amps. I didn't want to use the 24 VDC power supply either, so I found some DC to DC buck converters on Amazon (5 for $11.00) that use the LM2596HVS chip, which can handle the 48 volts from the stepper power supplies. I'll adjust the output of the buck converter for 12 volts. Using DC to DC buck converter seemed like a good choice since the 48 volts is already at the meters. No need to run another line across the cabinet. I powered the meters from a five volt source and they worked, but the LED display got brighter as I increased the voltage... to a point. So that's why I'll use 12 volts to power them. Here's a link to a community post I made with a pic of the wiring. czcams.com/channels/HOSNgw0wNxo6bzCCwvRPIQ.htmlcommunity

Great hack! Thanks 🎉
