Anyone else experiencing a loud almost grinding noise as the build platform drives downward as you start a build? My current zMotorTime=275683 i think that the units are in seconds but i have applied a small amount of motor lube so that drive screw it quieted it a little bit but not all the way is there a specific lube I should be using? or is this maybe a problem further down the machine?
I would ask for comment here from formlabs but if it were me the stuff I would use would be one of the white silicon greeses. Obviously not the spray kind. They sell it in tubes like toothpaste. Just dab a bit onto a finger and rub it onto the worm gear.
Petroleum based stuff can cause the plastic gear to polymerize.
