Warped geometry

[DrBwts 1]

 

I have printed the above piece before with no issues with but now with the same settings & the same filament I'm getting a kinda sag/warpage after some time.



Generic PLA on a UMS3

Anyone any idea why it should start doing this?

Only because I have done it myself a few times, but have you got PLA running on PETG settings?  Looks like could be running too hot and curling where the shallow overhang starts.

It was kinda as @mrender said. I had PETG in the 2nd extruder as soon as I disabled the extruder the prints started comming out fine.
