TAZ 4 Extruder Weight Reduction?

[Brew4You]

I thought the whole point of open source was to improve 3D printing, using the community to source innovation at an accelerated pace



I find with the current weight I get speed wobbles unless I print quite slowly.

The UM-TAZ difference for the most part here is not speed but acceleration. UM2 is set at 3000, I believe, and TAZ4 is at 500. I think this thread can tackle both of your comments.

linear bearing backlash, big X axis issues

Greetings, I’ve been printing with my TAZ 4 for a few months now, very happy by the quality and build volume. I came into serious issues with print quality very recently, let’s say in the past 2 weeks. I started to notice some oozing on the side of parts, usually when doing curved part. that was new to me, as I printed a lot of parts, including complex quadcopter parts, a full flexidually head (not finished yet, about to install the steppers on it) and more. Looking at the parts, I could see…

I’m also thinking about a dually bowden rig. But given that Lulzbot has a fleet of production printers with direct extrusion the tradeoffs to go to a bowden must not be that great.
