Ive done everything up to the point of burning the bootloader……..I hit the button and i get the error
"avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check."
Is there a driver i need to download in order to get my USBtinyISP to upload the bootloader?
LadyAda to the rescue (as is usual for her):
1 small problem….I have a Mac……..It says i dont need a driver but the led lights up and everything…..any advice?
LadyAda's page claims Mac OS X doesn't need drivers, but I don't know anything past that. Hopefully there's help from other Mac users who're using this…
Okay, more help:

Look at the first screen. Look like a familiar error code?
I think this means your Mac is seeing the programmer fine— the problem is with the connections to the chip on the board. Make sure the board has power, is wired properly, etc, and hopefully you'll get to go here. (One thing that seems likely is that you don't have the board powered, which would keep the programmer from seeing the chip.)
From the sound of things, your circuit fabrication has been less than a breeze, so you may want to take some pictures and ask some of the soldering gurus around here for advice.
Thats another problem, my power thingy wont turn on! any word on that?
If you mean the power supply, it's probably because it's not plugged into the mainboard.
If you don't have your mainboard finished, here's a hack that will let you run a power supply without a mainboard:

Be careful though! The green sense wire is inactive and needs to be connected to a BLACK GROUND WIRE because I think otherwise you could cause your power supply to emit smoke and stop working.
Do you mean mother board or main board? because my motherboard is finished….should the power light be on when i plug it in to usb? and how would i get around that hack so my power supply works? (how do i fix it without hacking it)
If your main board (the MakerBot board that accepts the big power supply socket) is assembled, just plug it in and your power supply should be able to turn on.
At this point I really need to stress that I don't have, nor am I using the mainboard you have, and don't know for sure whether it should be powered while you program it.
Anyone got answers on that?
Conrad2468: The power light of the motherboard will not work until the boot loader is burned and the Sanguino master firmware is uploaded. All but the main power supply (the only one that plugs into the motherboard) will also not work before, as they are switched by the firmware. It's really plug and play. No hacks necessary.

Thank you! I think my problem is bad solder connections or bridges which i removed (or i thought i removed) im just going to buy a new board i think mine is french toasted…..ive tried everything…..if you can provide some advice i would appreciate it much.
Just an observation on getting the firmware on the motherboard:
Once you have burned the bootloader, I didn't have any lights come on. Then I connected the USB-Serial cable and tried to load the firmware but got a "not responding" error.
Only once I had connected the power supply was I able to get the firmware to upload.
The telltale sign was that once I had connected the power supply to the motherboard, every time I pressed the reset button, I saw the red debug LED flash.
Pressing the reset button just after uploading the firmware worked for me (there are a few other opinions around on the forums)
Now you didnt have to hack the powersupply? or did you? (did you turn it on but it never actually turned on?
Hey, i encountered the same problem. However, i was able to power it up but i am still getting the same error message when i tryed to burn the bootloader.
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
can i skip this because it is powering up?
I had to supply power to both controllers via the PSU. I had to make a special cable to connect the extruder controller and the motherboard to get this to work (Basically didnt connect the data pins, just the 12v ones!)
Once you click upload or flash, THEN press the reset button. You will know once it works!
Im having this same trouble on both the Motherboard as well as the extruder controller board. How to i get around this error message? when i plug in the programmer into either one, i do not get any power to the board. I don't think it's a solder issue because when i plugged it up using the usb-ttl cable i do get power to the boards. help?
Did you solder the board correctly? I managed to screw two up….oh and go to
http://groups.google.com/group/makerbot/browse_thread/thread/541b39ab59318898
its pretty long but it helped me realized i was right…..(I FUBAR'd my MOBOs)
In that case I would hotwire the psu so it supplies power to the board. I had to make a cable to connect the extruder board to the motherboard that just had the power pins connected to supply the power to the extruder. If you are uk then i can make you one easily enough.
i have a white/yellowish residue on the bottom of my board from the solder. is this bad?
