Hello,
Can any one advise me on what the problem could be? The Y axis keeps trying to go forward at the stop point. Even though I set a position for my piece that is within the board I am getting a limit error.
This means that I have to find out why the home for Y axis isn't stopping and I need to learn how to fix this. Is anyone out there today?

1. What CNC do you have? 2. What is the 'stop point'? Home? Work Origin? 3. Does your CNC home correctly at power on? Home Position – Mechanical point set using magnetic limits switches. Near left (0,0).

Generally an inability to HOME is due to sensor alignment...but can also be caused by poor connection.
You are going to need to locate the Y axis proximity sensor, which can be found underneath the HOME side (left) gantry upright. That sensor should be pointing straight across the table parallel to the X axis.
When it comes HOME you should see a red light come on as it approaches the metal tab which will trigger the sensor.
There should be no great than a 1/8" gap between that sensor and the tab...If too large, or the sensor has gotten turned, then the response will not be strong enough or in the correct position.
*A test can be done by moving the Y axis farther back. Then place a piece of metal against the sensor....again that red light should come on...then while holding that metal in place against the face of the sensor, use the other hand to select HOME Y only on your controller.
The metal should trick the machine into thinking the Y axis is HOME...if the sensor is working. This would indicate that the problem is purely alignment or position of the sensor itself.
If the metal test doesn't work, then it can be assumed that either the connection to the sensor (where it plugs in about 6" from the sensor) is bad/broken etc...or the sensor has failed.
This can also be tested by swapping the Y axis sensor for the Z axis...but you will need to make sure that the sensor is in the correct position then.
Please feel free to give our service team a call if you have any questions. We can walk you through testing while you are at the machine.

Hi,
I just got this response. Thank you. I will test it out tomorrow and get back to you then. Thank you.

Gerry my machine is a Auto pro 6 with a 24x48 bed. When selecting yes to home when starting up, this failure happens. I am off to work now so I will test the tips I received from ATG tomorrow and will let you know how it works. Thanks a lot for your interest.
