PETG not sticking to supports on tight circle

Recommended Posts

Posted · PETG not sticking to supports on tight circle


I am doing a project and for the first time the first layer on top of my support is not sticking to the support material and as a result i just get straight lines of filament going from corner to corner and not creating the circle. It is only on the tightest part of the ark i am printing but everything else is fine. I have tried printing from 225-240 temp with no change so any advice would be great. I have my setting pretty good with PETG and do not get any stringing so i am not sure what to check next

    Hey @48T,


    Welcome to the Ultimaker Community 🚀

    This looks like a super interesting challenge and I would love to help. 

    Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 
    To save a project file go to File -> Save project.
