Will do. So far, things have been pretty straight forward. Marlin config has taken a bit, I will post the final Configuration.h and Configuration_adv.h when I'm done.

The biggest challenge was the Z-Probe. The logic on the endstops for the SKR is 5V, but the printrboard and probe are 12V. There was talk on the interwebs about solving the issue with a voltage divider with resistors - but that maxed out my electronics knowledge. A 5V inductive sensor was only $15 (for 2) so I bought them and it works perfectly and reliably.

I'm down to calibrating everything, and I'll do a final update once it's all done. My first print will be a board tray that can be fit up inside the metal plus underbelly. Right now, everything is wire spaghetti behind the printer.
