Probe/limit switch not working
When If the control software indicates that a limit switch is active or that it is not working, you can check which switch is involved.
To do this, go to the DIAGNOSTICS tab. Here you will see on the right side at ORGIN ''led 's'' at the X, Y and Z. When one or more led 's are lit, this means that switches are active. It is possible that a switch gets stuck. When you then disconnect the plugs of the different axes from the control box one by one, you can check at which motor/axis the led goes out. This way you know which switch it is.
Here you can also check the PROBE IN switch by manually lifting the torch slightly. The LED light will then light up on the screen.
