3d print issues

Hi.

I have some massive issues with my CR-10s4 printer.
Initially it worked perfect, but suddenly all my print gets extremely porous. I have tried to factory reset everything and slice the print from another computer to ensure it was not my slider settings.

All prints starts fine, but gets more and more porous as higher the print is.

I have tried replace entire hotend incl nozzle and extruder gear.

Tried different filament brand and materials, but with same result.

This objects is printet in PLA.

Layerhigh: 0.1 mm

Nozzle dia: 0.4

Nozzle temp: 205 decC (PLA rated for 190-210 deg C)

Bed: 60 degC

Anyone that can figure out whats going wrong?

Did you figure this out? I have the same issue with my printer!

I will try to turn off the cooling (fan) in your slicing program first to rule out low temperature on the nozzle. Most of under extrusion caused by too much cooling on the nozzle.
