Repetier can't change parameters

Printer = Rostock,
Repetier Firmware = 0.81
Board = Arduino Mega2560/Ramps1.4
Computer = Windows XP (also Ubuntu)
Arduino = 1.0.3 on windows and 1.0.4 on Ubuntu

I have got as far as getting all axis moving in the right direction, but am getting twice as much movement as is needed. Obviously the steps per revolution in Configuration.h needed changing from 200 to 400, but no luck. Then I couldn't change the behaviour of the end stops - and the baud rate is now stuck at 250,000. Arduino seems to think that it is programming O.K., but nothing changes. I have now tried this on a second board and with another computer, but no difference.

Any thoughts?

I bet you have eeprom enabled. As the docs say, new versions take parameter from eeprom not from configuration.h. You can set them in eeprom-settings in Repetier-Host when connected. If connection doesn't work you have to change EEPROM_MODE to a different value to overwrite with configuration.h values.

To reinitalize from configuration.h you can also use:

M502

Thanks, that did it - I will have to remember to think first before going into auto - change boards mode. One question though, where can I find the documentation on the firmware?

Thanks again,

Mike
