Cartesian Flying Extruder

A flying extruder makes a lot of sense on a delta, where it moves much less than the hotend (shorter distances and slower speeds) but it doesn’t seem like it would translate well to a cartesian printer.  I tried it anyways.  I didn’t like the artifacts I was getting from a long bowden drive or direct drive on my Eustathios, and in the process of shortening the bowden tube, I ended up with a cartesian version of a flying extruder setup.

RigidBot Modifications

Rigidbot

This is my 10in³ Rigidbot, part of the Rigidbot Kickstarter in May of 2013, and delivered in August of 2014.  Given the low price and large build area, I wasn’t really expecting a usable printer, but I figured it would be cheaper and easier than buying the parts to build one myself.  What was delivered was well beyond what I expected and I’m grateful to Michael Lundwall the Rigidbot team for everything they put into designing, manufacturing, and delivering this printer.

While the RigidBot was a great deal, print quality and reliability out of the box was not as good as my Afinia H-Series* (not surprising as the Rigidbot was a first gen machine sold at 1/4 the price with 6 times the build volume).  Since then I’ve upgraded, modified, and rebuilt the printer, it now works much better than the Afinia ever has (I have since given away the Afinia).  This list includes the current changes I’ve made to my printer, but does not include the temporary changes I’ve tried along the way.  Some of these changes were copied from or inspired by others in the Rigidbot Google+ community.
