Without the above there is not much help we can give you....
lmao - check the forum section before asking what printer :-)

Sounds like the bed material isn't as sticky to pla as it should be.
So you're getting a slight warp. Cheap pla will warp a bit.

Try rubbing a gluestick over it - pla loves pv-alcohol (the main active adhesive in glue sticks)
That will let the pla stick much better to the bed.
A couple layers should do to start.

I usually run the stick over the bed before a print and after removing one from the bed - that tidies up any gaps from pva sticking to the print.
