Swap from TPU to PLA and getting weird artifacts AGAIN!

Well I did the factory reset so they are empty atm. I guesss I’ll just have to swap back to TPU and do a flow calibration, then back to PLA and see if I get the same issues again. Thanks for the ideas, I think we are getting closer. But I still don’t know how the calibration of the TPU filiment would affect the PLA. I did follow the instructions as per your link.

Thanks for you’re help again. I asssumed you changed the filiment, and therefore k factor in the prepare tab via filiment choice. Not in the device tab here:

So I was defo just printing PLA with some crazy high k factor. Thanks for the assistance. As I would have not worked this out without the ideas.
