Extruder Upgrades

Hello everyone.

I’m considering upgrading the extruder to my Wanhao i3 clone.

Has anybody got any recommendations or suggestions which to avoid?

Hi Scott,

I’ve been having great success with a custom dual drive extruder I found on Thingiverse.

According to the page, you need to be careful to select a pancake stepper that does not hit the side when the nozzle is moved all the way to the right, or reduce the usable dimensions of the bed in your slicer to compensate for one that is too large. I’ve been using the stepper below with no issues in over a year.

You do loose some z height. I can go to about 145-150 mm height depending how lucky I feel. I think I may be able to get some of that back by modifying the top cross brace to allow the filament to pass through it (i.e. drill a hole/slot in it), but haven’t really needed the extra height yet, so haven’t done it.
