I have about 1400 hours on my TAZ 6 and just noticed that the herringbone gears on the extruder have about 1mm of “slap”. That is, I can move the big gear back and forth by about 1mm on its circumference and hear the teeth tapping against the smaller gear on the stepper motor.
What are the consequences of this slap on print quality? I have a brand new set of herringbone gears. Should I install them?
