Final positions for the DIN rails and wire management have been nailed down. It’s much more tight than one should really wire a panel like this, but it’s what I’m stuck with in order to cram it into the enclosure that I have. I still have to work out a “mezzanine” for the stepper drives. There’s a lot of unused depth on top of the power supplies, so I’m brainstorming some kind of hinged or otherwise easily removed bracket where the stepper drives can live.
I also need to make some decisions about how and where cables will enter and exit, taking advantage of the existing holes in the enclosure as much as possible. A filtered cooling fan and vent are also on the list of things to sort out.
