Parts not sticking to bed

[Sarnia]

Hi all,
I’m printing using a standard Artillery X1, the problem I’m having is that either my parts warp or they don’t stick to the bed or sometimes both, I’ve adjusted the temps up and down, currently using 57 c for bed and printing at 215 c using PLA, I made three parts with no problem at these temps, then tried to print eight parts over night and ended up with a big mess, I’ve tried tabs etc but getting frustrated now,
Any help greatly appreciated
Thanks

Clean your bed surface with 70% isopropyl alcohol or above,
If this does not work then raise the bed temp to 100C for a couple minutes clean and try again.
