Hello fellow reprappers! For a year or so I've been waiting for someone to develop computer vision algorithms to detect failed prints. Unfortunately I haven't come across any yet. I'm too excited about this idea, so I've decided help out on the development. I truly believe that the thing stopping this from being developed is data. In this case a labeled image dataset of both succeeded prints asby fredrudolf - General
Yesterday was a good day. Torbjörn came over for some printing and cinnamon tea. I temporarily removed my bed and couch to fit my ABC anchors. My room is approx 4x4m. Torbjörn doing some anchor calibration. Aaaand.. off we go! Looks surprisingly good for a first print. Here's a video, showing some printing action as well as the whole setup: https://photos.app.goo.gl/H1v2FSxzmzbJOS3z1 Andby fredrudolf - Hangprinter
The marriage is complete. The Hangprinter is now attached to the ceiling. Mazel tov! First I planned on attaching the printer directly to the ceiling. But I mounted two beams first and then mounted the printer onto the beams. It made the mounting much, much easier. The placing of the screws that mounted the printer onto the beams were strategically placed close to the D line rollers. Another twby fredrudolf - Hangprinter
Hello again fellow reprappers. Sorry about the horrible image hosting from my part. That ends today, thanks to tobben. I'll give him a cookie the next time I see him. Here's a repost of the previous images: Mmmmm. A Swedish smörgåsbord. http://hangprinter.org/fredrudolf/IMG_20171025_151844.jpg The electronics. Notice that I've got some line lasers.. because who doesn't want lasers on their 3Dby fredrudolf - Hangprinter
Hello fellow reprappers. Let's friggin build a Hangprinter version 3.3. This one has some additional stuff (not mentioned in the BOM on ), such as a raspberry pi with a camera. In this case, it's not to enable spying on your unknowing printer while you're away. Nono. It's to experiment with anchor localization (auto calibration) using openCV and apriltags. OpenCV is a computer vision library andby fredrudolf - Hangprinter
