Large x-axis shift during long print, help?

I had a print go wrong last night. It happened while I slept, so I don't know what happened.
About 1/2 through the print, the x-axis shifted about 1cm.
The print, both before and after the shift, looks very nice, but it's unusable.
I've never had this happen.

The models were sliced in Slic3r.

The x-axis belt is not loose.

Any thoughts, help, suggestions?

Thank you

Photo of print and printer would help.

Also - try turning off the filament sensor. There is a long thread about a firmware issue that the sensor being on might make worse.

A couple of other suggestions:

Make sure you print in high-power (not silent) mode.
Enable Z-lift in the slicer

Or you could search the forums for "layer shift". There's about 80 pages of hits.

I appreciate this is now 6 years on from the original post, however my Mini+ did exactly this last night.  Layer 4 shifted about 1 cm towards the z-axis which meant that as I stopped the print the print head tried to move beyond zero and made a grinding noise.

Did you ever find the cause of your large shift?  As indicated there are many posts about layer shifts but these all relate to small, millimetre, shifts as far as I can see.

Any thoughts or suggestions would be appreciated.  Could the input shaping be affecting this?

Cheers
