After many attempts to get my venerable Makerbot Cupcake CNC to print reliably, I’ve had enough. Its been a great learning experience, but I’m just not willing to put any more time into it. I’ve decided to make a reprap derivative, as I’m not willing to be tied into a brand that may or may not leave me high and dry again.
I’ve selected the Kossel delta printer for my build, for the very technical reason that it’s fun to watch them print. It looks like a spider spinning a web.
One of the apealing design features of the kossel is that it uses basicly the same motion system for each of the 3 sliders. No more shall I be debugging the X and Y motion, but having a complete new set of problems when I get to the Z.
I have some concerns around wear to the vertical colums of MakerBeam where the bearings roll accross them, but there are some ways to reduce these, and replacing the extrusion with new ones isn’t too expensive either.
The Kossel printes are still being activey developed with updates on http://deltabot.tumblr.com/ and https://github.com/jcrocholl/kossel, and has excelent community support through http://groups.google.com/group/deltabot.
With the last of my parts now arived, its time to start the assembly!
