Taylors Gregs Wades MK6 filament feed for Ultimaker

thingiverse

I modified Greg's Hinged Extruder for Ultimaker compatibility, featuring a MK5/MK6 drive gear setup. The design uses easily accessible metric parts, except for the MK6 drive gear and bearings, both available at Makerbot. Modifications include opening the hobbed bolt bore to accommodate the MK6 drive gear, shrinking the hobbed bolt bearing bores for 6mm bearings, relocating nut trap holes, adjusting filament feed hole positioning, moving the stepper back by 10.6mm, and mirroring the extruder. Additionally, a larger drive gear has been designed to mesh with the Ultimaker stock drive gear, eliminating the need for additional torque from the stepper motor. The design also includes changes to use M4 screws for springs, as M3 screws are hard to find. A mount for the Ultimaker is provided, along with instructions and a Kit BOM on kitbom.com. The extruder has been functioning well for over two months, including a 42-hour print session. However, it may result in popping bowden clips, so upgrading or replacing PEEK components is recommended. To complete the modification, you'll need two springs (11/32" OD x 1" Long), two MK6 drive gears and bearings from Makerbot, a 608 bearing (if needed), two 60mm M4 screws, four M4 nuts, one 50mm M6 bolt, three 13-16mm M3 screws, and some stiff springs. Adjust the extruder's E steps/mm to around 760, use Slic3r for slicing with a minimum layer time of 15 seconds, and print the gear perimeters at 20mm/s. Further instructions and mount images will be provided soon.
