I figured I should share this here as well (I originally posted to FB) but we did a write-up on our Longmill 30x30 build. If you need help building your table we have 3D models shared of our table build, and also some custom 3D printed parts for the controller box to make it mountable on a wall (or in our case, the side of the table).
The world is full of these excuses. That probably explains why I have a box with a few Pi 1’s, 2’s and 3’s. Finishing those projects/excuses is a different matter. But it does make me feel good to have them there “just in case”. The Pi4 does seem a bit more finicky and has cooling etc. needs as well the software still doesn’t seem fully baked for somethings, but no doubt that will keep improving every week.
