FAQs / Limit Switch Set up
« on: August 01, 2013, 08:33:45 PM »
Hello,
I am new to cnc and I am trying to set up my first machine. The problem I am having is with the homing and limit switches. I can set the homing switches for X,Y,and Z and they show up and activate on the diagnostics screen, and I am able to reset the reset button. The issue is when i activate any of X++,X--,Y++,Y--,Z++,or Z-- limit switches I get the error " limit switch triggered", but do not see any activation on the diagnostics screen and I cannot reset the reset button. I am running my switches in series, which if I read the manual correctly is acceptable. I have tried active high and active low. All switches are on the same input pin,( in series ). I have tried pushing the homing switches during the homing operation but it does nothing. What am I doing wrong? I am at a loss. Any help would be greatly appriciated.
Thank You,
Phill
