Clicking extruder after making dots

Hi, i have an issue when i do a print.
After the first layer, the k1 makes dots to fill in the gaps.
After that, my extruder starts clicking and it seems the nozzle is clogged.
If i am fast enough i can pull out the pla, cut a little piece of and feed it back in the extruder which upon the printer prints fine till the end.
I’m using cfs (problem also present before cfs upgrade)
E-sun pla, unicorn nozzle, no extra upgrades.
temp nozzle @ 230 (tried reducing it to 210 same result)
bed temp @ 50
Also tried different kind of pla, straight from the dryer, new ones, dif brands.
last but not least, i also did multiple system reset and calibratians to no avail.
Any thoughts are welcome to sort my problem out, thank you.
