I'm naming it the Tecrap.

First motions. Need to tweak the x axis pid some more. Can't find a happy middle ground. Either not enough power to move, or too much to hold idle.

Running the servos off of gecko drives, feeding it steps/dir from a ramps board running marlin.
Almost have the Y rough calibrated. I've done enough for one day.

I've changed the z setup internally to both run off of one servo. Have to figure out how to attach an extruder to it.

Why not at BioCurious? Probably because he's building a reprap out of
a $20,000 piece of equipment. ;-)

We're just about ready to start printing cells on our BioPrinter
though. That one's made out of a couple of $2 CD drives and some
Arduinos...

@Patrick, are you demonstrating it at fab8nz.com?
Anthony Atala from Wake Forest Institute for Regenerative Medicine  is talking on Bioprinting
