Artifacts in Cura slicing software

[Gafair 0]

I've been using Cura for about three years now on all my printers, Wanhao i3 plus Mono price V2 CR 10 and Japanese i3

Only recently have had problems and every one of my prince there's an artifact a quarter way up that sends the machine into a searching. And doesn't seem to know what to do. the artifact appears as two squares hanging off two sides of the front that only seen when I look at layers in Cara slicing

Any suggestions would be helpful. very confident with Cara trying to use other slicing software is going take me a little bit of time

Thank you

Monty

Look at your model in xray view. If you see anything in red that is the problem. Also make sure all plugins are disabled for your print (it remembers plugins from previous prints).
