How to go about correcting Layer Shifting


Topic starter

I am getting the same layer shift trying to print this part.. now twice. I enabled hopping to avoid the nozzle from impacting the print... but to no luck. I tried printing this again and it did the layer shift again..looks like in the exact same location. Any ideas? (Image attached)

Layer shift like that is caused by one of the axes not working correctly, either because the nozzle is impacting the part during a move or the axis is hitting something. I would check that your axes both move smoothly and with the same amount of force. If you find one doesn't move as freely as the other, it may be that you have a mechanical issue causing the layer shift other than a nozzle impact. I would try a different print to see if you get the same behavior. If so, open a support ticket since you will need to get into the mechanical parts to determine what is happening. 

If it is only that print my guess is that there is a feature that is causing warping and you are getting nozzle strikes during printing and not just rapids. Nozzle hop will help prevent nozzle strikes while moving rapidly but will not solve nozzle strikes that happen during printing.

You should also check that your nozzle isn't leaking as this will allow a buildup of material on the head that can cause this issue.

@bhudson thanks for the reply! I tried a different part and experienced the same y-axis shift.. the print starts off fine but then out of no where it starts shifting.. i have a ticket open..

Then you have one of three things:
1. Debris in the bed or in the Y axis drive that are preventing the operation of the Y axis motor. I saw a printer once that had debris wrapped around the Y drive pulley to the point the belt was over-tensioned.
2. The Y-Belt is too loose and is skipping teeth when the nozzle drags.
3. A failing Y axis motor. I have seen this a couple of times.
Your support ticket should be able to resolve the issue.
