PLA warping on flat surfaces

I think there might be some sort of misunderstanding or export error with this model?

This is how my first layer looks on my side, doesn’t have those artifacts. Is there something i could be missing or am i just really confused :sweat_smile:. I have over 6000hrs between 4 printers but english isn’t my first language so perhaps I’m not getting it?
As for the aux fan from some forum posts i have seen them mention heat creep with the 0,2 induction nozzles, so that’s what I am worried about. The problem at the start was lifting from the PLA support interface, not the base plate, the first layer is ok.

I have reuploaded the file, now in a ZIP maybe so it doesn’t corrupt on the way?

Please let me know if the issue persists on your end. Maybe we can talk on discord or zoom sometime so you can show me properly.

After a bit of time thread is dead so I’ll let anyone with the same issue know some fixes.

Lowering distance between support interface and print helped
changing from support for pla to pla
Changing from tree support to normal supports
Setting supports to be the same material, not multiple, same with interface

I don’t know what the people here were on about with the model, possibly just some wonky exports and a lot of misunderstanding.

What method did you use to align your model to the bed? Are you auto aligning or are you manually adjusting by changing the rotation of the part?

It comes with Z up from the cad software , I don’t need to rotate it.
