Hi,
I have a strange problem with my Nomad 3. Homing procedure works for X and Z but on Y it fails. The sensor is operating correctly and even stops the Y motor when it activates, but Carbide Motion fails with “hm009: the machine could not find the homing switches.”
I can also manually activate the Y switch with a steel ruler and see the red led turning on, I can also see the switch being activated in the debug window of Carbide Motion.
If I manually activate the switch during homing the Y motor stops moving, but I still get the same error message.
Any clues?
Photo of the underside of the machine?
Is anything mechanically interfering with the motion?
Is the table able to move the full length of travel? (note that it is possible to put workholding screws all the way through the bed and into the machine structure making it impossible to move the Y-axis)
With the power off I can manually turn the leadscrew to move the table so nothing is interfering. I even removed the aluminum table to see that nothing was stuck underneath, or in the slots.
An just to repeat: The sensor reacts, the motion stops when the sensor is activated, but somehow the initialization routine acts like the sensor never was activated. Since the sensor behaves correctly in the debug interface there is some serious strange thing going on here.

Could the prox switch have shifted slightly, so that whatever on the Y axis that would normally trigger it is no longer able to get close enough?
