Looking great! Following

Mpf is amazing!! If you aren’t quite proficient at python, or just want to jump start a ton of work MPF Is the way to go I would say. It’s a learning curve but once it starts to make sense, I see it saving huge amounts of time.

I use FAST - honestly I think PROC or fast are both great. Depending on the number of switches or drivers you need, one or the other might make more cost sense. One Main difference seems to be that fast is locked in at 256 serial LEDs unless you use fade candy (to add more), whereas PROC can be a mix of serial and parallel LEDs, but I believe you pay by the board to add LEDs vs having 256 channels built into the main fast board.

Cobrapin looks like a really great cheaper option, almost grabbed one on the Kickstarter.

Looks good. 3D print Router guides based off your inserts, should work perfect.

Pretty close fit! But man those router holes suck by hand though.. I think I have over 100 inserts on my game and I did every one by hand for the white wood. Hoping to use a template next time.. it was impossible to use a template the way I did it because I had the PF partially populated while routing. Of course CNC is really teh way to go if you can make it happen for a final version..
