today i noticed that after running either the extuder excerciser or the heat profiler for a while (eg 30mins) the console starts reporting IOException due to timeout, and the temperature stops changing. the boards still work otherwise though, and the heater seems to be accepting commands because the blink rate changes occasionally.
is anyone else having this problem? it's a little concerning because in the absence of new temperature data, the heater happily burns away until someone notices.
(sorry i don't have the exact text of the error message available at the moment).
we are running the firmware binary zip from the sourceforge page (v1.0), and an svn checkout of the java software (circa 6 oct 2007).
