    Yes, but only the first picture of the circle. I'll post another soon.

    Are you using a shell? Almost looks like all infill in one of your pics

    I am now. In my second picture I uploaded, I didn't use a shell by accident. I changed that and I am now using a 1.2 mm shell.

    Here is my print as it is going right now.

    That is where the bottom layer meets the infill. As you can see, the infill/bottom layer wont bond. Should I try it with no bottom layer?

    Im not sure im seeing it by the photos. Double check you getting a good squished layer on the 1st layer. Also want to check and see what the cooling fans are doing and when

    The bottom layer is what touches the glass. This looks like it is separating well above the glass -- at a transition point on the model?
    Or are you still doing a raft or something?

    You might need to post the stl.

    Try this one. I ran it through Azure.
    There may be a model error and if so this will help.

    For a second there I thought you just told me to shut up, then I realized...yeah, zip it.
    Thanks for giving me a laugh.

    I am printing another object right now. It is a camera holder(like the one in my second picture, except with infill), It's looking great. Could it just be circles that don't work?
    I'll try the new model after this camera holder is done.

    Thanks
    Eric

    I'll let a Cura dude (or dudet) comment on the profile.

    The pictures don't look anything like the model and that might be what you are getting at*.
    If so this is a model failure. Try the repaired one.


    *if you still have a raft or something going on then all bets are off.

    Bear in mind the printer at a low level can't do true circles (it is not a delta).
    Marlin calculates them out of splines :)
    However, at the visible level they should look pretty normal.

    I'm not using a raft. At this moment I am using a small brim of 10 layers just to make sure that the filament comes out before it actually starts printing the model.
    Model failure looks very likely, as this other print looks amazing, and has no layer problems.
    I have less than an hour on this print, so I think I'll just let it finish before I start the medallion/disc.

    Can you set the brim distance from the part ? Or can you turn off the brim and turn on a skirt ?

    Ill be home in an hour or two and will try to print your posted model

    Skirt is better for starting/confirming filament flow.
