When we try to bring the leadscrew up via the farmbot webapp it makes a sound like a grinding metal on metal situation with the flex coupling. Would adding a lubricant help that to not make that sound? Would it help to make the movement easier? What kind of lubricant is recommended?
Also, would it help our farmbot to add a sealant for the motor housing, just to ensure that water can’t get to the motor? Is there a recommended type of sealant?
