I’m planning to build a CoreXY printer, and I’m having problems finding the ‘perfect’ low cost printable extruder. Can you find me help me find the one that matches the following criteria?
-Bowden: to keep the weight of the print head low
-Geared: to apply enough pressure for smaller nozzles even with small or TMC2100 powered steppers
-Ergonomic: quick filament release is a big wish
-Economical: 3d printable if possible, not too exotic parts, vanilla NEMA 17, ideally Open Source
It’s supposed to feed a E3D v6 1.75mm 24V hotend (which comes with 4mm PTFE tubing).
What would be your take?
