How can I fix First Layer Adhesion with BL Touch - Tevo Tarantula
I have the same kind of issues I'm also using Sunlu white filament 210&nbsp;&deg;C and bed at 60&nbsp;&deg;C on a CR-10S also original BLtouch v3.1

On some parts of the bed it's okay but in the middle and some corners it's too high and doesn't stick (really annoying). I bought the BLtouch to avoid this kind of issues.

I have printed many things with no issues and with this filament It's making some trouble.

Ok I have solved the issue, the problem is Sunlu pla+ filament.

It seems that their filament is really hard to adhere to bed.

I found on another forum that you need to increase bed temperature up to 70° and head to 220 °c at least for the few first layers and don't go under 215°.

also moving the head a bit lower to skish the filament on bed.

I tried and got much better adhesion.

Hope it will help other people
