X axis detection impossible
Hi,
I finished to assemble my new MK3 but I have a big problem.
The installation wizard is blocked during the "X axis detection" and after few minutes it starts moving the x axis very slowly to the left. I try moving the three axis (X/Y/Z) in the menu of the printer and they all do the same...
Here is the video :

As you can see:
- The X axis move easily by hand
- At 28 secondes we can hear that the front fan is doing a strange noise (I untight the screw and it's the same)
- At 1 minute and 6 secondes, it start doing the X axis test but nothing happen
- At 2 minutes and 30 secondes, the X axis start moving very slowly
- At the end of the vidéo, the X axis end is not detected...
Thanks for your help
Re: X axis detection impossible
I think the screw to your X-end pulley is too tight and the pulley can not run freely.
Then loosen the two screws to extruder-idler. They should not stick out as your screws do. They should end about 1 mm inside from surface.
If the exruder-idler is to tight it will cause extrusion problems with overheated and klicking extruder motor.

Thanks for your answer but my pulley is totally free, in fact my problem is that all the 3 axis do the same, it's very strange ... It's like the Rambo MotherBoard do not send the signal to the motor as it should ...
I try to move all the 3 axis with the menu and they all move like in the video ...
Re: X axis detection impossible
Did you know that when you spin a stepper motor quickly, like you did when you slid the X axis back and forth, it makes voltage? It can be quite high and cause damage to the drivers. I see you moved it quickly enough that the LCD screen lit up. I would be concerned that you damaged the board possibly?

I found how to solve my problem. I flash the firmware and everything works fine. I think that the original firmware was corrupted.
