Fixed Gantry Conversion 3 - Kinematic Z

Without the SLM parts, I can't really make meaningful progress on the M0, so I decided to design a simple WS9290 top electronics mount. The plan is to reuse my existing 7040 in the PFA.

The current state of my electronics bay isn't pretty. I used to have a relatively clean setup, but as development picked up and I started swapping components, it went downhill quickly. I think the undersized 20x20mm kit cable canals were part of the problem.

So I'm tearing it all down and replacing the old electronics panel with a 3mm thick aluminum one. Wish me luck!
