Also on some machines, you can be in homing mode and push and hold -X direction button and the machine will move down and as soon as the dog switch comes off the ramp, the machine will reverse direction and finish the homing procedure. If the machine has a sticking switch, then it will overtravel. The upper cam/switch is the homing and the lower cam/switch is the emergency overtravel. When the upper switch first hits the cam it causes a deceleration, and then when it clears the cam it knows it is home.

We have some issues with our CNC machine with Fanuc M O controller. It started with a stuck switch below the table on the machine. We got the switch unstuck and testet the switch for function. But then the table was not near end travel on Y axis. The Y over travel alarm is generated when the ramp contacts the decel switch, then passes completely over it without homing. The hard overtravel switch is never depressed. What is the machine coordinates at in Y when it alarms?

After homing all axis, any movement more than .0196 (absolute) in the +x direction will trip the 500 overtravel +x alarm. I've swapped the limit switches with a spare from another machine and tested voltage on them.

The upper cam/switch is the homing and the lower cam/switch is the emergency overtravel. When the upper switch first hits the cam it causes a deceleration, and then when it clears the cam it knows it is home. It is possible to hit the hard stops if you aren't careful when homing the machine.

what is meant by cnc machine

Axis home troubles- How does "home" actually work ? This on the Y axis of a small VMC vintage 1987 with Fanuc OM control. Y axis will overtravel every time when attempting home. Usually this sort of thing is the result of a sticking limit switch but not this time. A switch only on one end of travel suffices on tens of thousands of cnc's on the market for homing. Stall sensing seems way overkill for a 3d printer. It is a simple matter to count the step output from the Prop simultaneously with counting a quad encoder on the shaft.

Also on some machines, you can be in homing mode and push and hold -X direction button and the machine will move down and as soon as the dog switch comes off the ramp, the machine will reverse direction and finish the homing procedure. If the machine has a sticking switch, then it will overtravel. The upper cam/switch is the homing and the lower cam/switch is the emergency overtravel. When the upper switch first hits the cam it causes a deceleration, and then when it clears the cam it knows it is home. We have some issues with our CNC machine with Fanuc M O controller.

The Y over travel alarm is generated when the ramp contacts the decel switch, then passes completely over it without homing. The hard overtravel switch is never depressed. What is the machine coordinates at in Y when it alarms?

I can zero return ANY TWO axes and the third will then overtravel in a manner that sounds similar to yours. My work around solution has been to zero return x and y and then back off the y axis just enough to extinguish the y axis zero return lamp. After homing all axis, any movement more than .0196 (absolute) in the +x direction will trip the 500 overtravel +x alarm. I've swapped the limit switches with a spare from another machine and tested voltage on them. The upper cam/switch is the homing and the lower cam/switch is the emergency overtravel.
