x-axis onley goes to the left

Hi,

I bought a pursa i3 pro B and everything works exept the x-axis.
It moves with no problem to the left but not to the right so the extruder will move to the left until it hit the side and crash.

Auto home works for every axis.

New discovery.

I took of one cable for the z-axis motor (accident) and everything workt perfectly exept that only one z-axis motor worked.

Is it underpowered?

I took of one cable (accident) for the z-axis motor and everything worked perfektly exept it was just one z-axis step motor on.

Is it underpowered?

You plug y motor and one of the fans in wrong direction. I am worried that the fan is dead.
And please take some picture of printer(front side, back side, left side), I want to see the color of endstops wires.

oki Ill try to fix it but the y-motor will go in the wrong direction thats why I plugged it that way.

How about re-uploading the firmware? The firmware has been sent to your email, you can refer to this page to upload it:

i updated the firemware but to no succes.

The y-steppmotor goes the wrong way and the x-steppmotor have no power to move the extruder.
the fan works good ant the z-motor works good.

Do you have any idé what I have missed?

Do you have a multimeter? If you have, please test something:
1. Test if there are 2 groups of 12V output voltage from PSU when you turn on the printer.

2. Can you move the x axis by your hand easily? If not, please loosen the x belt slightly.
If you can move the x axis easily, test the voltage between the screw on x motor driver and GND as shown in the picture, the voltage should be around 0.9V, rotate the screw slightly to calibrate the voltage:

When does the y axis go in the wrong way? Homing or when you want to move the y axis separately?
