I'm a product design intern and use Cura professionally. I'm currently working on a new product and have had several successful prints of this part but after I updated to cura 3.4.0, the parts are failing. When I look at the sliced model in Cura, there is no first layer for the support I need for the part. Now the support lines ALWAYS pulling up. Why is the support not starting on the first layer? Seems like that would be a requirement in order to get a good print. How do I fix this or should I downgrade to a previous version of Cura?
