Print issues on 2 printers

Hi All,

I have a FFCX and a FFC Pro which have been working fine until today, both printers have suddenly started producing varying thicknesses in the print walls as per the image that I hope works below.

Any suggestions : ABS - Bed 105 - Extruder 225
Attachment 9441

tiny little picture in which everything looks okay.

if both are doing the same thing - sounds like an environmental issue maybe.

I'd agree - maybe your filament has picked up some humidity from the air.
