you can refer to it:
I have a Pro B with a GT2560 rev A+. As the initial board stopped working at a certain point I have ordered a new one.
What I did:
- used Arduino 1.0.1 as recommended
- upload the firmware
The display shows the printer ready but going into Prepare-->Auto Home nothing happens.
I have tried also to get the .hex file (https://www.geeetech.com/download.html?download_id=34) and upload it using XLoader. No error but still nothing happens.
Strange thing, the old motherboard did not required an USB connection to power up. The new one (even is the same - GT2560 rev a+), does not power up unless the USB connection is present.
Can anyone advise what I should do to get this printer back to life? I read so many pages on the forums but not clear at all what should I do or what I am doing wrong.
