Prints wont stick to heatbed

[DeathsmileZ]

My prints just wont stick to the heatbed no matter ehat i do. I have a modified ender 3 pro with a bltouch running on a skr 1.4 with tmc5160 running on the newest marlin 2.0. on it is a microswiss hotend with a E3D V6 Nozzle X - 1,75 mm.
Ive tried bilinear leveling aswell as ubl but havent seen any difference. I have a hood for my printer from whambam but that just ended up with the filament getting soft in the extruder and getting stuck. I have no idea what to do anymore.

A picture of what my prints look like most of the time:

what surface are you printing on ?
And what filament are you printing with ?

Also a properly FLAT manually adjusted bed is generally a lot simpler and effective than the 'auto levelling'.

You are most likely printing either too far from the bed or too close to it.

Have you tried adjusting the z-axis offset to change nozzle distance from bed ?

Had a build surface that no matter what I did nothing would stick, believe it or not went to a cheap Chinese bed surface and most of my problems with filament not sticking are gone.
This was regardless of what filament I was using PLA / ABS / ECT....

There are some prints that I have to finesse the layer to the correct height by using baby steps, this was enable in my Marlin firmware.
I Enables baby stepping in Marlin then added a few skirts around the model that needs help,
While printing the skirt I slowly adjust baby steps while watching until I see that perfect layer an problem solved.
Before using baby steps I would spend many hours adjusting using every method described to me an missing this perfect height.

Now using the baby steps function with my new build surface I can adjust this perfect layer in a few seconds...
Who knows maybe if I have the other build surface I could make a perfect print on it now.

((( Why is my Post Formating getting messed up )))

yeah.
I';m usign a free print surface on my klic-n-print that i got free at a tct show.
No clue what it is, but it works well.
And using a cheap self adhesive cheet of PEI on the sapphire pro.
Also excellent.

Failing that print glue tends to work well.

But this sounds like an 'auto level' setting to me.

I am also using this free print that is working well.
