Region of Rumpled Parts

Need thoughts on how to troubleshoot problem shown in attached. Two parts in back right of print rumpled.) X-level runs prior to each print. Uneven build plate heat or out-of-level or…?? Filament is PLA

What settings are you using? If you’re just working with a stock profile please include the brand of PLA and the detail setting you have selected when slicing this model. I would also like to see some photos of the bottom layer of your print just to make sure this isn’t an issue with your first layer that is then manifest along the whole surface of your print. Finally could you post the model that you are trying to print that is shown in the photo? Some of the issue may be in the model itself or the way it is slicing and I want to play around with it a bit and see if I can spot where things might be going wrong.
