The PCB-Mill still needs some software tweaks, so I may get them manufactured at a PCB house and try the mill at my next project.
Meanwhile I started writing a test program. For testing I use a NodeMCU board. I use this nice library by squix to communicate with the OLED.
Today I printed the buttons for the controller. The surface finish isn't that beautiful, but they fit nicely into the top acrylic plate.
I have access to a small CNC-Milling machine. Therefore I designed an 1-layer board with relative thick traces 0.4mm (15.75 mils). I wasn't able to route everything on the top layer, so I have to use some jumper wires for the bottom layer.
The controller is made out of 2mm laser cut Acrylic plates. The parts are held together with M3 and M2.5 screws and nuts.
