Problems with movement of printhead in ultimaker s5

[gameboysank 0]

I recently removed some plastic stuck in the printhead and reinstalled it. However, the printhead vibrates and makes a loud noise . When I try to home it, it seems like it only moves in the y direction and not completely in the x. I guess the x axis motor is bad since the belt on it does not move smoothly in one direction. It goes back and forth on the pulley. Is interchanging motors a safe way to test this theory?

 

Anyone else having similar issues   ?

Could you please take a short video?  Steppers are incredibly tough and your printer is pretty tough as well.  I'm guessing the problem is that the limit switch isn't getting hit.  For the X axis the limit switch is in the rear left corner in the top of the machine.  It's easy for that to get loose or moved or for nothing to be pushing against it.

 

It's extremely rare that a stepper needs to be replaced.  However, sometimes a stepper driver fails.  But your description isn't specific enough.  I really need to see a video.

If you are good with ssh you can make your S5 in "developer" mode from the controller.  Then it will how it's ip address at the top.  You can ssh into the machine using username/password ultimaker/ultimaker and then send gcodes to move the X and Y axes without having to home the axes.

 

You can also swap cables and the problem moves to the Y stepper then it is indeed the stepper driver.  But I haven't ruled out the "limit switch" possibility without seeing a video first.

As gr5 writes, difficult to find such a fault from text.

 

Back and forth sounds like a blocked drive.

I would try to move the axle manually.

Also times move the axis away from the limit switch to see if the moves there again and bumps.

If the axis is stuck at the limit switch, the limit switch is the culprit.

 

If it's not blocked, there may be a phase missing from the motor's connector.

If it's not, it's the motor driver.

In the last two cases, I would call in support.
