Pla not sticking to HBP!

[6010fd12]

Alright so first of all I am VERY new to 3d printing. I was trying to print a phone stand on it's side and for some reason after it is finished printing the raft and starts on the stand itself, some parts of the raft starts bending/curling up as shown on the photo below and that messes up the entire print. That only happens after the raft is finished, since it sicks well while printing the raft.

Here are the settings that I have used to print this.

I have tried low temps and fast print as well as slow prints and high temps (as you see on the settings)


I do have the HBP at 115 C
I have red that people say it should be 40-50 C but the instructions in the Creator X said to set it to 115 but that might be the cause of the curls.


I have also leveled the bed as best as I could.




NOTE: This is not the first print. I have successfully printed a 20mm cube with these settings.
