UM2 + feed motor running in reverse direction

[wwjayne 0]

Our UM2+ has been a work horse and has given us many hours of service without any problems. A week ago we noticed the filament was feeding in reverse as it was printing. When we tried to change the material reversing the material fed the filament forward and not in reverse. Sending a command to feed the material forward sends the material into reverse. We tried what the forums suggested and loaded an UM2 + EXTENDED  configuration. This still didn't fix the problem. Any suggestions will be appreciated.

This happens a lot.  There are 2 likely possibilities but the most likely is that you have the wrong firmware.  The UM2 firmware rotates backwards from the UM2+ firmware.  So make sure you have the white UM2+ feeder and install the "plus" firmware.  Or if you have the black feeder then install the UM2 plain firmware.
