PETG Printing Artifacts

Hi All,

I'm using Simplify 3D and the Prusa profiles included by default.

When I print a Calibration Cube at 200% scale in PLA, it comes out perfect - as with Slic3r.

When I print a Calibration Cube at any scale in PETG (Prusa's own brand) I get artifacts on the print that I cannot work out.

For example, the bottom of the cube, the edges are all great, except the middle looks very messed up. I have no idea what causes it so, so no idea what settings to play with to dial it in. This effect gets worse the larger the object - the more surface area on the first layer, the worse it gets.

Since I don't know what caused them, I don't know what settings to adjust to see what works - ideas are welcome!

Re: PETG Printing Artifacts

Did you change your z level for PETG? Try printing something else but slice it in Slic3r instead.

Looks like your Live-Z is a bit low, try to move up a bit (less negative).

Hi Both,

Thanks for you replies - for some reason this forum doesn't tell me when someone has replied to my posts so apologies for my lack of response.

I adjusted the z axis and finally got good prints out of slic3r PE and PrusaControl but cannot get the same out of Simplify3D no matter what I do. I shall have to look at calibration.

However i have other issues - worthy of another post. Thanks.
