Today I tested out machining acrylic with my CNC. I used a 1/8" end mill and machined out my home's street number in 1/4" clear acrylic at a depth of 1/8". It turned out pretty well for a first attempt but the bottom of each pocket wasn't very smooth. There was also tiny "islands" of plastic that weren't cut out in several pockets. I painted the numbers black and will check tomorrow how well that turned out.
Bulb-ramping project still on-going. I got the encoder to switch between states and display the current selection on an LCD.
