Delta effector with orbiter extruder

thingiverse

I always wanted a direct drive extruder on my delta printer (a modified anycubic kossel). Due to the low mass of the orbiter extruder, it makes it the ideal candidate for my little experiment. So I'm happy to share my design of the orbiter extruder delta effector. Delta effector offset: 40mm (i know is quite big but i had to be sure that the nema14 motor of the extruder will not touch the diagonal rods. Probe offset: -15.35mm, using a regular endstop switch. Distance between rod joins: 43mm. Plenty of space for custom cardanic articulations The part cooling duct: i printed mine in Fiberlogy TPU 40d. It's ridiculously temp resistant, keeping its shape. Using this design, i managed to print TPU 40D @100mm/s wall speed (50mm/s outer wall speed) with success. Al other parts where printed in regular PLA, 3 walls and 20% infill. For the leveling probe, i used 2 magnets: height - 3.75mm, diameter: 12mm There is a small PTFE tube between the extruder and the hotend. After inserting the PTFE tube in the hotend, let 9mm outside to fit into the extruder. When you will secure the effector onto the effector, the tube will be constrained and immovable. !!! Don't worry about the curvature of the tube. The inclination of the effector is 30 degrees and does not affect the path of the filament The downside of this design is the mass: although the orbiter is lightweight, 150g added to the effector forced me to lower jerk and acceleration: Print acceleration: 1000 mm/s^2 Jerk: 15mm/s travel move speed: 180mm/s
