I failed to notice the numbering on your schematic for the lcd- the pins 1-16 are reversed, because I attached it on the underside of the panel. Works great now!

The wires are going to the correct location, but my sd card, for instance, was plugged in 22,21,19,18... etc instead of 14,15,16...22. I can control the speed blind (well, with nothing but the O character and running dash), which tells me at least the encoder is plugged in correctly (with arrows towards the reset button)

But I am still seeing nothing but squaresville in the LCD- Brightness and contrast adjusted.

Maybe I uncommented the wrong section, think I did it for the ultipanel, but would this happen if I also uncommented sd card support?

Something you have done is wrong .. it sounds like its drawing excessive current by the sound of it. Does it work if the kit is unplugged ?

Did you upgrade the firmware ? install the 128 ?

You probably have checked this though.

My Solidoodle kinda steps slightly every 15 seconds, and I can see white squares in the LCD momentarily when this happens. When the Panelolu is plugged in, I can't connect to Repetier host. Did I not change the firmware comment correctly? I rechecked my wiring, everything rings out correctly, any thoughts? Thanks
