Mystery fail.
There’s no alarm.
It stops in mid program just before the G97 line, (Retraction of turret before next tool)
It occurs after ten to twelve hours of continuous use.
Has anyone seen this??
I have found with and without spindle rotation, the coolant is flowing and the tool has reached its safe X and Z out of the material.
There are NO alarm messages no indication that it has a problem.
It’s just sitting there on the X and Z line, before G97.
And it happens nearly 11 hours after it was first started and began running parts.
I suspect a proximity sensor is failing with time as it heats up and losing a accurate field of view. Possible relay, failure.
Other issues that may not be related:
The quick setter arm... when used had errors as much as 20 thousandth inaccuracies.
Currently the quick setter no longer provides a change in tool length.
Any thoughts are welcome.
