Hello,
I was wondering if someone has seen a problem like this photo. Is this usually caused by a belt slipping?

Hello!
The first think I would do is definitely to make sure the belt pulleys are not rotating on the shaft. Check that the set screws are on the flat pad of the output shaft.
Another thing that could be causing this problem for you is if there isn’t enough power getting to the stepper motors. If the stepper motor driver isn;t sending enough current then the motor could be skipping steps and causing the misalignment. If you do turn up the power (usually a little knob on the driver you can turn with a screwdriver) then make sure not to turn it up too far or you might run the risk of burning out the motor.
Since the part in the photo you posted is printed on an angle it is hard to tell if only one of the axes is being faulty.
Hope this helps,
Martin
When printing something that is tall, thin and vertical, it doesn’t have enough structure to hold itself in place properly. So when the nozzle touches it the print moves in the opposite direction and layers shift all over the place. What you have to do is design in some lateral supports,that is a couple of walls that are perpendicular to the print to give it that lateral stability.They don’t have be to very thick and can be made to snap off once the print is done.
So instead of your print looking like this:
-------------------------
it will look like this

(Please excuse the crudity of the model. I didn’t have time to build it to scale or paint it)
Thanks! I’ll check this now
Nice Back to the Future reference. lol!
I would go with something a little loose or slipping also. It seems the error started fairly quick but I see areas where it is trying and seems to stabilize for a bit. I had some layer shifting on my machine (QIDI) and it turned out the Z threaded drive rod was a bit dry and sticking causing the bed to twist side to side a bit.
Take a look at print speed, may want to slow way down.
This is a belt slipping, OR it is that your end stop is hitting, OR the wiring to your X or Y stepper motor has gone bad, which is quite common because the motor cable moves the same over and over until it finally breaks.
