Great job!  I like the MendelMax 2.0, I've got an early 1.5 that doesn't have the linear rail upgrades.  Love the cardboard fix for airflow!  Simple & practical solutions!! :)

tBone Cape
The tBone 3D printer / CNC cape has been announced for the BeagleBone.  It looks like an interesting board with some unique features.  I like the use of more sophisticated stepper driver chips from Trinamic, and the support for higher-current stepper motors...

I don't get it why they need additional ATmel microcontroller...

Several folks were very excited to see the CRAMPS board.  There were a number of printer vendors present, and they all see the need to move off of the AVR based Arduino and are looking to see what is going to be next.  It was great to be at the show and be able personally advocate for the BeagleBone as a machine control solution.

Anyone displaying at the Midwest RepRap Festival next weekend?  I am unable to make it but have a free CRAMPS board for anyone willing to hook it to some motors and run a demo.  Serious bonus points (and more free stuff!) if you can hook it to any sort of printer.  Contact me privately (email is best: charles at steinkuehler.net) if you're interested.  I really want LinuxCNC on the 'Bone represented at the festival, and I'm not sure if anyone else will be showing that.

+Brad Hopper I have generally had the best luck running the Axis GUI, although I switch to the DRO tab instead of the backplot display since 3D acceleration is not yet working on the 'Bone.  You can use any of the available LinuxCNC GUIs, but Axis seems to be the most common and the most stable.  I want to have a GUI customized for fewer pixels and 3D printing, but no one has made one yet and it's fairly far down my list of things that need to get implemented.

CRAMPS Update

T-bone
 
+TheBrick2
loss of torque is mainly an issue at high verlocity. high ustep resolution is useful to increase the position accuracy at low velocity. therefore different resolutions for different velocities are the best. our T-Bone cape offers flexible resolution with up to 1/256 usteps: www.tbone.cc

Wally kinematics are non-trivial. Motion planning from cartesian to polar and back is interesting. I'm devoting part of today to it. Hope I want some progress.

Good thing you had an extra BBB or two lying around!
