Hi there,
after replacing my heat block due to threads damaged i have a strange problem... If i print single wall cube i have terrible underextrusion and need to raise multiplier up to 1.6 to have right thickness!.. But if i print the same object with double wall i need to go back to 1 - 1.1 to have the right thickness!!... Replaced nozzle, checked e-steps calibration nothing is changed!!!... Had anyone similar problems? Before this happens i had acceleration settings calibrated, extrusion speeds and managed to print nice and smooth up to 80 speeds.
Any suggestions are welcome
