Sk-Go Dragon-Orbiter extruder

thingiverse

Sk-go extruder using the Dragon hotend and Orbiter extruder. It's designed to fit snugly on the Sk-go X beam, to be as small as possible and have a center of gravity almost centered on the beam. Unfortunately I couldn't positionned the extruder more to the left so you will loose about 5mm of the bed on the left. To get a better coverage of the BL-Touch it's best to move the bed back since the BL-touch is 50mm back. I printed it all in Atomic Carbon fiber ABS for durability. No support needed anywhere, some small break away supports are included in the model at the belt attachment point and there is a sacrificial layer at a couple holes. It's pretty straight forward to assemble, m3 square nuts everywhere there is a pocket for it. One on the carriage in the front at the top needs to be glued in to help assembly. A few things are screwed into plastic, it's best to use an an m3 tap first so the screws go in easy. I'm using the original Orbiter with the heatbreak system that I chamfered at the top and I used a small 11.6mm piece of ptfe tube. BL Touch is positioned: #define NOZZLE_TO_PROBE_OFFSET { -26, 55, -1.55 } My e-steps for the Orbiter is 696.43 It's been working well for me printing PETG, I've tried a couple times to improve the cooling duct but it's still far from great to cool PLA. I included the Fusion file and a Step so if you want to have a go at designing a better fan duct be my guest and don't forget to share ;)
