Graber i3 Day 9: Firmware settings
I’ve got the Sanguinololu from botronics with installed sprinter/marlin firmware. The first tests were promising. 
But how do I set (alter) my values that I can calibrate the Graber i3? Its a beginner question I know. 
What host software are you using?
All of the config settings are in Configuration.h in Marlin.
Calibration (from http://freenode.net/#reprap):
[21:31] calibration?
[21:31] calibration is http://youtu.be/wAL9d7FgInk and is also http://calculator.josefprusa.cz/ and is also http://reprap.org/wiki/Calibration and http://reprap.org/wiki/Triffid_Hunter's_Calibration_Guide and http://www.thingiverse.com/thing:5573 and is also https://sites.google.com/site/repraplogphase/calibration-of-your-reprap
If your board came with a firmware already installed, you’re going to have to figure out how to setup your Arduino environment. I originally had sprinter on my sanguinololu from botztronics with Optiboot. with a 1284 mcu. It took me a long time and a lot of gooling to figure out how to set up the right board. And I honestly don’t know how to do it again. When switching to Marlin or Repeteir, I needed to change what level of Arduino used to compile the sketches, again, I can’t for my life recall how I did this.
I just know under Tools> Boards, I have two separate board configs I can use, one for Sprinter, and one for MArlin or Repeteir.
If you have MArlin, go into configuration.h as mentioned before and change all your settings. Be sure to go to the EEPROM section and uncomment the
#define EEPROM_SETTINGS
This will allow you to change many of the configuration settings through Repeteir Host, instead of going through Arduino and having to compile and upload.
Good luck, navigating Arduino and the getting the board set up the first time was a pain for me.
@lynnroth By now I used printrun.
@Eric_Moy Thanks for your replay. I’m not sure if I should give +1 for it.
@Shane_Graber Thanks, I will take a look at them
@Eric_Moy Today I was finally able to upload the firmware. I had to use the Arduino IDE and Marlin FW from Botronicz (Ken) · GitHub
Glad you got it working. I totally feel your frustration
