Question about Arduino install, stuck (Page 1 of 2)

What board do you have? Do you actually have the old sanguinololu and not the new printrboard?

If you have the sanguinololu then you need to use the 644P and not the 1284. The 1284 is an upgrade that you can do but solidoodle shipped the sanguinololu with the 644p.

Any guesses to my Arduino question?

Sounds to me like you have a printrboard, in which case you're going about this all wrong.

http://reprap.org/wiki/Printrboard

Thank you fellas. I appreciate the help.

As far as I've read its not plug and play yet. You need some way to control the printer, ie say "start"

I havn't looked at adding an LCD yet but im sure the Printrboard website has some plans

Well, I went ahead with the instructions to compile the firmware. It said "compiling..." then burped. This is the error:

1286\cores\at90usb1286/main.cpp:6: undefined reference to `setup'
C:\Users\Kent\Downloads\arduino0022\arduino-0022\hardware\at90usb1286\cores\at90usb1286/main.cpp:8: undefined reference to `loop'

Now what, please? That path and file DO exist on my computer. I have anti-virus, malware, SONAR, etc. turned off. I am connected to, and plugged into, the printer and the green LED is on.

(I did go to the Arduino forum and read all the FAQs, no luck.)

BTW, in the instructions I'm following it says:

Go to Tools, Boards, and select either "[USBtinyISP]Teensylu/Printrboard" or "[BootloaderCDC]Teensylu/Printrboard]"
Once you have configured your firmware, hold "shift" and click "compile" for the verbose output.

"Once you have configured your firmware" what does that mean, exactly? I didn't configure anything, the screen was blank after I selected at90usb1286, so I just Compiled.

Okay, what's the format for that? Thanks.

Okay, here is the Configuration.H file. If, when this is all done, I am to pull together a tutorial on all this, I need to include this stuff WITH the correct settings. Can you guys please assist here. I'm not an Arduino guy and I can't even spell E3D, so your assistance is appreciated.
