Hi,

I have just finished building my I3 Pro B and have a problem with my X axis not moving.

I have:
Tested and can confirm that all a4988 drivers have at least 0.8V (and none are higher than 1.2V)
Swapped the X axis stepper motor connection on the GT2560 Board,with the Y axis port.... I am then able to move the X axis through the Y axis control. But the Y axis then won't move. I have tested this through the LCD control and through the Repetier UI
I've swapped the A4988 from the Z axis with the X axis, still the same problem (So i've now discounted there being an issue with the A4988 driver)
Loaded the latest Marlin firmware (didn't work, i just had the blocks [] on the LCD )
Loaded the latest ProB firmware as per the topic on this site (currently loaded, and still the same issue)
I've loaded the ProB firmware several times through the 1.0.1 Arduino UI and still have the same issue

In the firmware, i had to swap the endpoints for the Y axis, is there something I need to do for the X axis? (I've scanned all the files when loaded in to Arduino 1.0.1 and there's nothing that screams 'X axis disabled'...

I can't think of what else to try? - other than swapping out the GT2560?

Hi,

have you solved your problem?
My Printer has the same problem and I tried everything as you did.
Would really appreciate if you would answer me;)

Hi, have you ever detected that your motor cable is properly connected to the motherboard?

Have you tried to switch the motor wires of other axes to the motors of other axes to see if the motor is working properly?

If the motor is running normally, then you need to replace the x-axis motor cable.

If the motor still does not work, you may need to replace the motor.

Hi!

Thank you for your post! I have exactly the same problem. When I switch the connection of the x-motor to the one of the y-motor on the 2560 board, the motor moves, so it is not the cable nor the motor. However, when I connect it to the x-axis motor position, nothing is moving. I measured the voltage on the board for the motor and it is around 1V. Any help is very much appreciated.

Thank you

Hi, You are referring to the problem of the motor socket on your motherboard.
If you have passed the test, you need to replace the motherboard.

Hi

I have received a new moterhboard and it works now perfectly! Thank you for the fast and uncomplicated support! That was really nice.


thank you
