I don't see your config.g file - did you forget to attach it?

The M305 commands in the config file look OK to me. The next thing to check is that they have been processed. Try sending M305 P0 and see what it returns. Similarly, try sending M305 P1.

My guess is that the config.g file you have edited is not being read at startup. Some things to try:

1. Run M503 to see if config.g can be read from the SD card at all. If so, check that it is the right config.g by looking for R4700 in the M305 commands. Perhaps you put the config.g file in the wrong place (it needs to go in the /sys directory).

2. Try a different SD card.
