Are this 2 LEDs lit when you turn on the printer? And please check the microstep of y motor: If you are using A4988, the number of jumper cap under A4988 should be 3.

Hi,
no only one led is on.

Hello,
Under each A4988 are 3 Junpers set.

Hi,
as you can see in the picture, there is only one led on.
And i checked the microstep setting too: there are 3 jumper
under each A4988.

Over high currect caused 10A fuse burnt, you need to replace a new fuse.

Hi,
do you have any idea, how the fuse is gone?? Remember, the printer was only in stand-by, without any motion and the extruder and the bed where off too.

And could you post me the correct reference of this fuse.

thank you

Some where is short circuit, so the fuse is gone.
The reference of the fuse is 10A/125V.

hi,
today i received an order of littlefuse.
i spend 3 fuses to identify the faulty part. The A4988 of the x-axis caused the short!

i replaced it temporary with the A4988 of extruder 2 and i printed my first calibration object
without any further problems.
