my gt2560 board doesnt work well. after i assembled the printer it works for a view days and i had succsessful printed, but sometimes the display and fans turned off and i could not get any connection to the printer after some trys it worked again. i dont had the time to try for a few weeks, but now it seems that i can get no connection anymore. the fans still dont turn on and the display is dark. the led on the board is on. i have already checked the wires many times. everything is connected like shown in the build-instructions.

i have already send a message to the seller. he wants to post my problem in the forum first.

Hi,
You can refer to this post to make some troubleshooting with a multimeter(the PSU,some voltage on the board):

And maybe you can attach some pictures so i can diagnose the issue easier?

I have already noticed that the 15A fuse is dead, at the 10A fuse i can measure 12V. I have replaced the 15A fuse to a new one from my lokal store. But it still dont work. Maybe the new fuse were instant dead again. The PSU works well.

Hello again,

is there something else i can do? I need the printer for a project at my university really soon.

Hi,
I guess you may have a wrong measurement...
I'm afraid you need to replace the 10A fuse,it was broken.
The 12V means the voltage between each side of the fuse and GND,not between the two sides of the fuse.
You can replace the 10A fuse to have a try.
