How can I download Repetier Firmware from arduino?

As above. I want to download the configuration from the Arduino on my setup (Ramps 1.4, Rostock)

Further info: Many months ago, in an excited thrashing about when everything was going wrong and the gods seemed against me - it suddenly went right. The sheer relief drove any thought of doing my normal meticulous documentation* from my mind and I can't be sure even if I have still got the Arduino files - on one of a huge range of drives, memory sticks etc..

Many thanks,

Mike

* O.K., occasionally meticulous documentation

If I understand you, you want the configuration of your firmware from your existing firmware

If you have eeprom enabled all you need to do is send the printer a m503

This will list all configurable parameters.

If you don’t have eeprom enabled, this command will return nothing and there is no way to recover the settings.
