Hey, Sorry to hear you’re having problems. I run a FlashForge Dreamer and get consistent prints. I found for the best success it first comes down to making sure your bed is level but with the correct amount of clearance for the nozzles.
I use the calibrate feature and take a piece of printer paper and slide it back and forth while adjusting the bed until a noise can be heard from the paper dragging. I normally try to level my bed off two or three times right in a row to make sure they are all adjusted. Too tight and it won’t apply right, too loose and the prints won’t stick either. Once you’re sure the bed is adjusted correctly. You can use two different techniques. My favorite for PLA is blue painters tape and hair spray. I don’t recommend heating the bed at all. I used a heated bed with hairspray and PLA and could barely get my prints off the bed! For ABS blue painters tape and a heated bed is required. ABS is much harder to get to stick without warping. I now print mostly with just PLA on a glass bed. The glass is nice as you can clean and prep it outside of your machine. I use 70 heated bed and just hairspray and it gives great prints!
Don’t give up, the Creator Pro is a great printer, I would double check the bed has the correct clearance, then try to run PLA with painters tape and hairspray. Also, I would run FlashForge Print software. I use Simplify3D and it is fantastic and worth the money.
