Update on dual extruder mod for RoBo3D
Finalized the design for my cold end and am just waiting on some hardware before I can install it. Ended up buying all the parts I need to finish this month instead of next.
Only major revision was the location of the heatsink fan. Now I have two blowing through as this saves space on the x axis.
Really nice design.
Wow, impressive! Do you have Designs/STLs available?
Nice. You’ve got some serious Z wobble on those prints though - what were they printed on?
@Tim_Rastall looks more like an over-swinging/oscillating X or Y axis to me. I’d guess it was printed on the Robo - their Kickstarter prints showed similar artifacts, which are typical for those wobbly triangular frames.
@Tim_Rastall the carriage, part fan mount, and jhead plates were printed on a replicator 2x. The rest was printed on my robo 3d
@denix not yet, I don’t feel comfortable releasing files till I know they actually work
@Mike_Kelly_Mike_Make please keep us updated! I’d be interested to play with dual-extrusion on my Robo too…
