Gummix

Hello, I'm new here to Forum. Short to me, I come from germany, am a carpenter, 30 years old and have a CoreXY do-it-yourself printer. To my problem: I switched from S3D to Cura because their pricing policy and update interval is against the grain. With Cura everything works fine, only one problem I can't get a handle on. The holes have partially no contact to the inner walls (With S3D I did not have the problem, therefore I exclude a hardware error). Can somebody help me?

same error here on Win10.

Hello, i have a problem with Cura on my CAD PC. When i press "prepare" Than i first get "unable to slice" and then "slicing". But Cura don't start to slice. On my normal PC everything works normal. I hope you can help me.
