Thank you for recognizing that many people were having trouble downloading the FW. I have been trying for a few weeks to get past this issue, the FW Rita sent me with the Arduino sketch already created worked. Again thank you!

Of course there are 2 interface for 2 Z motors. You should extend one of the motors with a Dupont line, and the other interface for Z motor is below the second A4988

^^^ I would ask that you post a photo of this as I see only 4 motor connections (X, Y, Z and extruder). I do not find any place ...

John,
Yes, I have the Tools\Board\Sanguino ATmega1264p 16mhz selected along with comm 2. I verified comm 2 is correct under Control Panel\Device Manager. This comm port displays and disappears as I plug or unplug the USB cable connected to the Sanguino board.

So after working the past 3 days on learning Arduino I have gotten to the point where I can using the FW provided by Rita compile a sketch without errors. Yet when I try to download to the Sanguinololu board I receive an error: AVRdude: stk500_GetSync():not in sync: resp=0x00

any advice on how to ...

John,
I am sure you mean well, and I would assume that for someone who has already been shown how to successfully upload firmware it may not be difficult. So from the perspective of someone who has not been shown, nor has been successful allow me to describe the difficulty I have with your ...

Pardon me if I am a little frustrated, but I am unable to load the FW. There are large gaps in your FW procedure, I cannot resolve or even get close to resolving the FW issue on this Sanguinololu board. I will need either clear and concise directions on how to install the FW I was provided or a new ...

Let me know if this issue was resolved. I had the same concern and found a solution. If you are still in need I will share how I went about solving the problem.

Rita,
I received the FW thank you.

Rita,
I do not see an e-mail from you yet?

Ms. Rita,
If you would be so kind as to email it to me I would be grateful.
