Hi. I cannot stop Cura putting support around the outside of the part. The walls are vertical, so why is the support there? The support blocker is not working. The problem is this adds time to the print and wastes material, also the support strings across over the PLA wall and impacts the quality of the print.

Any advice would be greatly appreciated.

Thanks,

Paul.

    "support horizontal expansion".  Set that to zero.

     

    For many (most?) prints you want that on.  It has to do with the fact that if your part is mostly vertical with holes in the sides you want the support that sticks into those holes to be able to reach the bed.  Because PVA doesn't stick on top of PLA all the great and having a connection down to the glass helps a lot.

     

    But humans are smarter than cura so you can change this value.
