Hello. I got some problems with my CTC Prusa i3 wooden 3d printer. This was a cheap kit of eBay. And the seller has locked the bootloader. So there is no way to upload a new firmware to the device.
I am trying to use a Arduino as ISP and connect to the iscp port on GT2560. But I can't seem to get it right.
If I connect it as this post describe, I get invalid signature.
Can someone confirm which ports to use?

This is my device. The 10pin port is rotated, but I have tried different wiring.
Thanks
