G2s Firmware Burn Issues

[bridge2nowhere]

I built my printer, it responds in Repetier, so I know it's connecting via USB and communication is basically working.


I tried to update the firmware, and I keep getting an

Code: Select all

avrdude: stk500_getsync(): not in sync: resp=0x00

error

1. I'm using Arduino IDE 1.0.5 on Win10
2. I downloaded the latest firmware
3. I set the board to "Mega 2560 or Mega ADK'
4. I selected "Serial 3", which matches what I used in Repetier to connect.
5. I dragged all the files in the firmware folder over to the Arduino window
6. I clicked "Sketch"->"Verify/Compile"
7. I clicked "Burn Bootloader"
8. It tries for a couple seconds, and then throws the error

I have tried 3 different USB cables.
I've pressed all the rest buttons
I've restarted my computer

"7. I clicked "Burn Bootloader""
Why do you click burn bootloader when upload the firmware?

The directions weren't clear on how to actually update the file, and I've never worked Arduino IDE before.

If you added that you click File-> Upload to upload the file, it would have helped a lot.

Don't know whether your bootloader is damaged or not, but you can refer the link here and try to re-install the firmware:

and if you want to download the firmware, find the one for your printer here:

Is the GT2560 programmed as a Arduino Mega 2560 or a Sanguino?

it's the mega 2560.
