This week we’re testing out the Othermill with acrylic. We recently has an issue with the Flashforge creator pro 3d printer where we needed to remove the faceplate in order to fix it – We noticed the acrylic faceplate was completely blank on the back side. So we thought it’d be neat to CNC mill something cool on it. We had several simple ideas like putting an Adafruit logo on it, but that would make it seem like Adafruit manufactures 3D printers (which we don’t) so we thought we’d put a face on it instead.

Using a 1/8″ end mill, it only took ~6 minutes to carve the whole design. The size of the acrylic faceplate just about takes up the whole spoiler bed. Because the end mill is so large, it produced lots of chip making it hard to see the design in the time-lapse (and that’s with the FanBit installed).
