Hi Karl,
Great design as per usual!
I've run into an issue where the inner circles on layer 33 (for me) do not have any supports underneath. I can adjust the wall line count and the X/Y support distance as per your guide, though I am not getting any good results.
There is a similar issue seen before, where the solution appears to be adjusting the design itself:

Please see images below:
Layer 32, just before inner circles printed. Note there is no support.

Layer 33, inner circles first layer but no support underneath.

Alternative method, though dashes are made which will likely end up causing print failures. They are not attached to the circles already printed.

Can you advise on how to get around this? Perhaps a change to the design based on the linked thread? Worst case is I print it upside down which gets over this problem, though I hope the print looks good :)
Thanks,
Jonathan.
For anyone else having issues, I switched to Prusa for this specific part. With the help of Karl it seemed like a SW or Cura settings issue, but with default settings issues still showed with supports enabled.
Hi Jonathan,
I turned on support for this print. Have you you tried that?
