With this change a mechanical or optical switch may be used to check the availability of the filament and when the filament runs out an M600 (filament change) command is issued. This is only done while printing with an SD card. This feature was requested several times (issue #679), but the requests were not accepted since it was believed that this situation should be handled at host side. However during an SD print the control is totally on firmware and I think that during an SD print it should be handled by the firmware. The original code was posted at reprap forum (http://forums.reprap.org/read.php?1,297350) by Lazymonk. I have only corrected some bugs of the code and improved it by adding definitions to the configuration.h in order to make it more standardized.
