Hi @elnadav12,
Been away for some times..
Just wonder if your nozzle is just too big or maybe to much worn?
As you've changed parts in order to any remove mechanical play(?). This lines might move slightly in and out due to worn out -or too big nozzle size. Have a look at this -I'll assuming you're using a standard size 0.4 mm.
However, your nozzle tip looks "some" worn to me (see last picture).
Good luck.
Thanks

Hi, thanks for the response. It's a brand new 0.4 nozzle.
I think I resolved the issue, I noticed the feeder is "ticking" at low speeds, probably not getting enough current.
Although, when loading filament I tried to pull it as hard as I could and it kept feeding.
I looked online and found a new official "beta" firmware for the UM2+ that was released quietly in 2018.
I installed it and prints seem perfect now. Also fixed the ticking noises.

If you read this and have the same issue, just download the HEX file and upload it to the printer in cura 🙂

Hi @elnadav12,
Thanks for the feedback, great finding.
I'm using the same firmware version (slightly modified for my printer).
Uneven feeding can occurs due to too low current setting, Extruder current setting is 1250 mA.
Good catch.
Thanks
Torgeir
