Ive been struggling slightly with bed levelling on my ender 3v2 for a while. I can level it but even with the yellow springs ive had to level it before ever print and its still not perfect.
I decided to invest in a bltouch, installed it yesterday along with the JyersUI firmware and updated icons and what a game changer.
Perfect prints straight away. The bltouch probes the bed in a 3x3 mesh before a print and then i get perfect first layers and great prints. Wished id invested a long time ago
So if anyone is on the fence about upgrading to a bltouch, trust me, do it.
The install was pretty straightforward, just watch a number of youtube videos.
The same goes for the jyersui firmware.

Below are a couple of photos of the new firmware

You don't need the Jyers UI screen firmware it just makes it look nicer.
The BLtouch should sort out the uneven bed after you've set the Z offset in the centre.
How are you printing via SD card or octopi?
You need the correct G code either setup in your slicer software or octopi to perform a new mesh before you print
The code G29 will use the bltouch to create the mesh before you print.
 
Have you manual levelled your bed?
Those mesh figures seem way too high. You are looking for around 0.05 or less. The centre of your bed is nearly there but everywhere else is way out.
You need to lower your top right to start with.
I create a mesh in the firmware and then manual level the bed by adjusting the appropriate wheel, in your case top right and then create another mesh.
The BLtouch will compensate but it's not the Bible for getting level, your still need to get the bed as level as you can buy adjusting your wheels and then the bltouch will then compensate for any unevenness on the build plate itself
 
The touch sensor is there to sort out a warped bed. Just make sure its 'nearly' level using the wheel knobs and then the touch sensor will sort out the differences.
I only use a ABL 3x3 mesh and have no issues with the sensor.
Is it a clone bl touch? or a creality one?.
 
As i had a spare z end stop switch left over after installing the BLTouch i decided to print off a filament runout sensor.
Heres the link for the one i used.

Ender 3 V2 filament sensor using z-stop by Kosaro - Thingiverse

Works perfectly, had to resize the ball to 105% before printing, have it connected directly to octopi using 2 pins.

Ground from the sensor goes to pin 6
and switch goes to pin 15

then i used the filament sensor simplified addon on OctoPi and set the correct pin etc in the configuration.
 
Yes you can edit the gcode and put the g28 followed by g29 in the code so you dont need to reslice.
Only insert g29 after g28.
The g29 command just creates a mesh before every print which if its a 3x3 mesh only takes an extra minute to do and well worth it.
 
Another nice addition. Octopi running on a Raspberry Pi3b+ with a cheap 3.5inch touch screen
Octodash is the front end and lets me control the printer totally from loading filament, printing, pausing, and gives a nice frontend.

 
It's strange because your cl touch should allow for any slight bed issues. You shouldn't have to adjust your Z offset once it's initially set.
It may be worth going to manual leveling within jyers and select to use cltouch.
What this will then do is measure the z offset at each of the for corners and tell you how far out they are, you then manually adjust the nobs on the relevant corners until your within 0.050
It basically assists you to manual level the for corners and then from them on, set your Z offset once and then the cltouch will take over and make any sought adjustments as it's printing.
I set my z offset when I first installed the bltouch and haven't changed it since
 
Excellent news Huggy, it looks like you've sorted the issue out. I thought it was something to do with the CR Touch as this should have been sorting out
any minor levelling issues. Its just trial and error with 3d printers but once they are dialled in they print great, until the next time!! :)
