Partially Solved X axis issue

Hello Forum,
This is my first 3D printer and I am experience a problem from the start before I could print any object. I am a true beginner. It is the first time we use the printer. The Z and Y axes move as supposed which mean that the associated stepper motors work fine: I can move the bed back and forth (Y axis) and the extruder up and down (Z axis) from the control panel but the extruder does not move side to side at all (X axis). The X- and X+ in the control panel are both grey and nothing happens when I press them. When trying to print an object, the printer simply goes back and forth (bed moves back and forth) and everything gets printed on a blobby line...

What can I check? Is it possible that some wire is not connected or is connected incorrectly?

The stepper motor responsible for the X-axis is the one mounted with the extruder, correct? Could that motor be broken?

I see a small white connector not plugged anywhere. What is that connector for?

Is there a detailed user manual somewhere online showing all the ROBO printer's parts, i.e. each stepper motors part, etc.?

Thank you for your help. Here some pictures:

1) Picture 7725: this picture should show the x-axis motor (as you indicated) and the white connector. I will look more carefully but I don't see where this connector would connect...

3) Pictures 7274 and 7279: this stepper motor is for the z-axis, correct? the y-axis motors are located below the bed. Where is the stepper motor driver (small chip) for this stepper motor? Is it visible from the pictures?

3) Picture 7277: how high should the motor be from bed? Is there a prescribed height?

Thank you again!

Thank you Geoff and Mark.

I guess the two autolevel switches you are referring to are the red and black vertical wires connected to the stepper motor in figure 7277 and you are say they dont look like they are pushed in (i.e. pushed upward) completely, correct?

 

Thank you.

1) I have connected the white connector under the stepper motor on the right and now the extruder moves along all three axes. However, when I try printing one of the objects in the library the extruder does not come down close to the bed height and remains up there in the air. Is there a problem with auto-leveling? I think I read I should disable auto-leveling.

Which axis does the stepper motor located where the extruder is move?

2) Also, from the picture below, I think I need to adjust the extruder height so it is even on both sides, correct?



What is the orange button below? What does it do?



From the picture below, do you think there is a problem with the connector/support (the one with the two wires) under the stepper motor? Should it be oriented in a different way?

 

Thanks everyone.

Regarding the autolevel orange switch, when should I just press it? Before starting the print? how can I access it if I rotate it under the x-axis carriage?

 

Ok, thanks.

I will turn it to the right (based on the picture) so it is under the x-axis carriage. Once there, it will be pressed by the cross-bar when needed (your point is).
