It looks fine to me. I don't understand the M420 command. I'm not familiar with that - it's not a UM (ultimaker) standard. According to this:
https://reprap.org/wiki/G-code#M420:_Leveling_On.2FOff.2FFade_.28Marlin.29
The "Z2" means mesh compensation ends at Z=2mm (so it compensates from Z=0 until Z=2).
Could it be that your mesh compensation values are off?
I'm adding "cr20" to your topic title so that people who own a creality will notice your topic. This is an Ultimaker forum so most people own Ultimakers or have cura questions. Your question is cura related but is more of a creality specific question.
Hi, there.
Thank's for replying , I know nothing about mesh :(.

Hi there,
Whenever I start printing, Cura just raises the nozzle high and the filament doesn't stick to the bed. I have to LIVE adjust Z offset everytime.
I have a Creality Cr20 Pro.
This is my G-code, If someone can gladly help me please? Much much appreciated.

Cura Printing first layer too high on CR20
in UltiMaker Cura

Hey man, I managed to fix the problem.
It was the bed levelling issue on the cr20 pro causing problems. What I mean is that the CR20 pro has only two knobs which you can adjust and are located on the right side. What happens is when you adjust those knobs, the bed lifts from the right and goes down on the left and makes the bed slanting. If you don't tighten those nuts it will simple wobble around. What I did is bought some turning knobs and springs off amazon and manually calibrated the bed. Thank's for replying back and try to help me. I now need some adjustments due some layers are being printed rough which I will try to reduce the flow to 90% and raise the nozzle up a little and hope it works. Also set Cura initial layer flow to 200% with 0.23mm layer height and the first print sticks, also if it doesn't I can manually live adjust using the baby Z steps and lower the nozzle down for the first layer and than up it again.
Super thanks man.
