Geared Z Steppers

[TechMasterJoe]

To be honest.. I havent noticed a real improvement.. If it has improved its minor as the stock setup is already pretty decent. im still happy with the improvements.. but its a case of diminishing returns..
if the system is already 90% good.. spending the money for a 1-2% increase is hard to notice.

try disabling micro stepping your mech is far more accurate then micro stepping is anyways plus it will bring your Steps per mm down to a level marlin can handle

your first layer accuracy is based on the accuracy of the probe and how close it is to the nozzle
get a cheery mx keyboard switch they are +-.02mm the basic endstop switch is +-.40mm with an avg of .10mm with a good one
or do some type of optical arm
