Hi everyone,
Lately I have been annoyed by the loud grinding noise of the Z axis and the slow speed at which the farm robot moves - it is too loud for anyone walking into the greenhouse to hear, and it is very slow.
I know that graphite lubricant can be used on the drive shaft, but that doesn't help much. I recently listened to the motor at high speed, and surprisingly, it was much quieter. It is still a bit slow, though.
I have six NEMA 17 stepper motors with sun gear reducers, encoders, and hardware available to modify them. They are much faster and very quiet.
I have also looked into using PTFE plastic rods instead of the aluminum Z axis drive shaft, as this plastic is oil treated and has lubricating properties.
Does anyone have any ideas? I think this should not be difficult to execute.

Pictures?
Stepper make noise when moving, slow motion=lot of vibrations/sound.
Using microstepping drives will lower the vibrations/noise, using TMC drives can make them very quiet.
Can not offer more help as we need to know how stuff is setup/mounted/executed.
