I'm running a Prusa Mendel V2 with a Sanguinololu controller, SD Ramps with modified connector for Sanguino, Marlin 1.0.0 RC2 firmware, slicer and prontoface. I can load and print from prontoface just fine. At the end of the print, the platform is moved to the front, all motors are shutdown and the heaters are shutdown. Life is good! When put the file on an SD card (using and USB to uSD adapter) and then fire-off the print from prontoface, the build goes fine until the very end. At then end, the motors are left on, bed and extruder at last temperature and the build plate is not moved forward. This would normally not be much of an issue, with the exception that I get a glob of plastic where the head stopped moving. This seems like a firmware issue, but not sure. Sorry if posted in the wrong forum.
