Re: Bowden strength question
I recently swapped my Jhead out for an e3d mk5. Pushing the filament through by hand takes much less effort now. My steppers are 4.4kg torque and both heads extruded ok but the Jhead oozed much more....

I thought I'd heard of a 3DR variant that used the extrusions for linear motion. Does that ring a bell for anyone? Can you point me to it?
View ArticleRe: 3DR Variant Without ground rods and bearings
I believe it is either the Kossel or the Cerberus that use the extrusions for their linear motion. You can probably just use their vertical carriages instead of the ones with the 3DR to use the...

Hey, I really like the idea of the bearings on the rods. Thanks for posting :)

Nice idea (tu) What are the advantages of this design vs. the other column types? What are you going to use for the vertical rods? You could use 6 bearings vs. the 8 on the carriages, reducing the...
