I'm not sure I'm posting this in the rite discussion forum, i have an two sided problem that I'm hoping i could get some help or input with. The auto tool zero works intermittently, i just set it up but what baffles me is when i go over to the diagnostics tab the digitize light is lit (green) along with M2++limit,M2--Limit and M2 Home in yellow. Any comments or hints would be appreciated. Thanks in advance.
