Hi all. I bought a acrillic i3 pro B from ebay. assembled OK, had some funny anomalies so i updated the firmware. After update it showed err. overtemp and frozen control panel and no matter what I do I cant reload or update the firmware. comes up with time out. Ive plugged it into a laptop first and found an article stating the usb might not have enough power so I plugged it into a tower, no luck. Some suggest a new boot loader but it has to be flashed with another audrino and I dont have one.
Any Suggestions

Could you post some pictures of the error msg?
BTW,could your board be detected by your computer?

So I did more testing, installed Repelier server and noticed connection to the printer would drop every 10 seconds. That would be a good reason for failed firmware update. So I presume its a failed gt2650 board.

Didn't use Repetier Server...
But did you test it in Repetier Host?

My printer is Prusa I3 X 3D printer DIY kit I have lost the SD card I need the marlin kofigurations file which is on the map to adjust the parameters please left me the file
Or please the complete contents of the sd map me left here without I come no further

I forgot, there is another setting that needs to be changed. I don't have it in front of me, but it lets the head travel past the Z endstop. That will let you get to where you need to be. Otherwise it stops at zero instead of -1 where you need to be.
