Our Formlabs 3L printer had serious issue with filling tank action taking too long. New print would sometimes stall at filling tank up to 8 hours. After many trial and errors we came up with idea that our resin level sensor might be faulty. Overfilling tank with 4L of resin would trigger to start the print immediately without any LCD prompts. Measuring the exact distance from resin level we developed ultrasonic end-stop, so that we could trigger print process manually without waiting when all the cartridges will be emptied. I’ll share the 3D model so that you guys could enjoy more printing then filling until we get fully manual mode for our 3L.
You will additionally require 1 x neodymium magnet (20 mm x 10 mm x 1 mm) and some adhesive.
