I see a lot of people having the issues with the print coming off the plate, but I think that could be fixed by adding a brim; however, I’m wondering why the supports couldn’t be removed - they seem to have fused pretty solidly here.
Need more information, but if you are printing in PLA - then you can use PTEG supports or vice versa. It will lead to longer cycle time but will greatly improve the supports removal. Could also try Tree - Slim support, double check your gap between the print and the support. Send a pic of your Support Tab settings
