M200 Plus Z-PETG strange irregular side first layer

Hi there,
i’m printing Z-Petg with normal setting and every time i have this irregular side (just on one side) on the first layer…
Can someone help Me?


It looks like it can be caused by the platform that needs to be calibrated.

Also it’s always good to perform it’s maintenance once in a while, material could be stacked inside.

Best Regards

I have calibrated the platform but the strange things is that it happens only with Z-PETG
