Deep grooves in 3D print?

[vikassi17 0]

Hi Everyone, 

 

For the last few weeks I've had some really weird printing problems where I'm getting really deep grooves in my prints.  I've leveled the bed countless times, tried different print settings, but I cant figure this out.  See the attached picture.  Anyone ever have this problem and if so, how did you go about fixing it?

 

Thanks!

Hey @vikassi17,

Oh wow, that doesn't look good. 😖 
 

I'm super curious what could cause this.  

Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 
To save a project file go to File -> Save project.

 

Thank you 🙏
