[Why is the 1000th layer shifted]

I  forgot to say that it's a shift in the Y axe JohnInOttawa so the Z axe can't be guilty for that problem

[Why is the 1000th layer shifted]

I have a Tevo Tornado and I recently started to print some big things (more than 100 layer) and with every of these there is a layer wich shift all the next ones by few millimeters.

Wich is very annoying when you want to print some precise things.

I tried to print the object with a new created g.code and nothing changed. I tried to creat another profil but nothing changed.

I don't see anything else to try.

Thank you for your help
