Servo driven nozzle wiper arm for delta printers
thingiverse
I'm a big fan of having a dedicated dump area on my 3D printers, where they can prime the extruder and wipe the tip before hitting the print surface. This setup allows for seamless printing without any pesky hairs or globs getting in the way. It worked like a charm with my modified Bukobot, but when it comes to deltatypes, you can't just extend the axis to prime it off the table. So, I came up with a quick and dirty solution that does the trick.
