While this is just a simple test of the Ultimaker API, it’s surprisingly high up on the Google results when you search, ‘Ultimaker API’. That’s a shame, because there’s a lot of power under the hood of this printer. If you have some sort of mod you’d like to throw into the ring, here’s the Hackaday Tip Line.
