Stepper/belt problems

Hi All,

First major issue I've had with the printer and it's a bit strange...

I start a print and all seems ok (I have noticed the occasional knocking sound in the movement but not all the time). After the first layer, there is a loud noise (stepper/belt skipping?) and the print head tries to move beyond the edge. Then that makes everything go out of line and I have to abort.

Now the confession - I got my finger caught in it when trying to remove some stringing for a 'work in progress' picture. This made the belt slip and the print head go out of line. But, after aborting the print and restarting, it printed ok (and then another part after it).

Every print will now fail with the symptoms described above. :(

Please help

-Stu

    I had that problem. Ticking sound when moving. The pulleys/belt might be misaligned causing 'click-clack'. Check that the belts/pulleys/shaft are aligned so the belt pass aligned to the belt. Aligning that will remove the sound. You need to calibrate at the end of all that ofc.

    This can help to diagnose if this is the problem:

    BtwI think I think misunderstood your problem. Indeed you might have a pulley lossing grip or a belt with oil making it slip. Also check the belt tension just in case.

    All sorted! It is printing like new 8)

    It wasn't loose pulleys, but misaligned rods. Labern, that link was super helpful thanks!!

     

    That's great. The misalignment was going to be my next guess so glad you found it.
