What type of filament are you using? You mention the brand, but don't say what it is. Have you tried multiple filament types/brands?

Its 1.75mm PLA+ I've also used another brand of PLA with similar results. I've used this brand consistently with no issues before installing the BL Touch

it looks like your sensor is triggering inconsistently. is it an original BL-touch or one made of Chinesium?

nope, its an original - it does seem to complete the mesh ok, its just when it prints I can't get consistency in things sticking to the bed. Is it worth me trying to post a probing output?

Isn't is too close? The skirt is very thin. Are you sure the gap is too big?

it looks to me like it's both, the skirt and parts to the left of the model seem to be very squashed but the right hand side and back left corner aren't sticking to the bed.

Hope someone might have a view on where to go with this. My prints were coming out pretty good, but since installing a BL Touch to the printer I've been unable to get consistent first layer adhesion.

I have the same kind of issues I'm also using Sunlu white filament 210 °C and bed at 60 °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
