* Updated sdcardlib
* Heater power reporting. Useful for PID monitoring.

This firmware is optimized for Ultimaker's gen6 electronics (including the Ultimaker 1.5.x daughterboard and Arduino Mega 2560).

The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.

* M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
* M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.


Configuring and compilation:
============================


Install the arduino software IDE/toolset v22
http://www.arduino.cc/en/Main/Software

For gen6 and sanguinololu the Sanguino directory in the Marlin dir needs to be copied to the arduino environment.
copy Marlin\sanguino <arduino home>\hardware\Sanguino

Install Ultimaker's RepG 25 build
http://software.ultimaker.com
For SD handling and as better substitute (apart from stl manipulation) download
