So I think a small piece of filament must have landed between the herringbone gears as a few teeth on one side of the small gear have crumbled off. I love how these parts can be printed to fix and upgrade the machine, but I don’t have any friends with 3d printers. Looks like the Lulzbot spareshttp://www.lulzbot.com/?q=products/gregs-wade-reloaded-extruder are out of stock (see after selecting a colour), would someone ship one to Australia for Bitcoins/Paypal?
Also after removing the extruder motor from the extrusion assembly it appears to have problems itself… does it take much to fry these things? When I give it the extrude command (overriding cold extrusion prevention) it basically vibrates and doesn’t rotate unless I give it a twist. Has anyone else suffer the same thing? Wondering if I need to order a Nema 17 too.
