Hey gang… I haven’t had any problems yet with dirty z-axis or IHS switch… Resting voltage always at 0.0v. But, I’m curious what your typical maintenance to the z and surrounding areas may be… Do you treat things just like the x and y lead screws? 3 in 1 oil typically for me… Anything special for the switch? I was thinking a spritz of contact cleaner at the very least… Anything else you do special?
One of the first things I did when I got the table was to cut and install taller stanchion plates and add a machine torch… a side benefit has been lesser spray on the z-etc…
Looking for anyone to chime in here!!
