Prusa Mini missing top layer

Firmware: 4.3.1
bootloader: 1.0.0

Lately having problems with top layer missing on prints, but the weird thing is that its not on every print

i can print a set of 4 logos without any issues, and then reprint the same file and have missing top layers

First print - no issues:

________________________________________________________________

2nd print with top layer issues:

Things i have tried:

  • Complete hotend replaced
  • Extruder stepper motor ( just because i had one )
  • Bearings in extruder body
  • Plastic parts - all extruder parts
  • PTFE tubes in in/out of extruder stepper body
  • Extruder driven gear

Any pointers to what i should try now ?
