Are you able to turn off mechanical centering? Or can you adjust the settings?

The only reason you would need to run this calibration is if the camera was replaced or the centering camera got whacked which is highly unlikely. If your placements are off, put an offset in the parameter file.

To narrow down the cause. Have you test it on all your tools? If only particular tool(s) having issue, then it might be tool that's having the problem.

Yes, for all tools... The tool head stops just above the tool

It is probably one of the Z lock solenoids not working properly. These are located along the Z axis and as part of the initiation of the machine, the Z measure the travel. Check the upper and lower Z locks

I've checked the locks in the service program and the solenoids move when told to.. also I can see them opening when going to pick up a tool..

when the machine initiates the last move it does is in the Z axis. If memory serves me, during the last Z move it drives down and measures the stroke, if the lower solenoid is not fully retracted the axis measures the wrong travel limits. Hopefully t

You mean that the problem could be that the solenoid retracts but not all the way?
Electronics Forum | Wed Oct 24 09:25:23 EDT 2018 | filipblad
The solenoids seem to work properly and there are no problems when initiating the Z-axis
Electronics Forum | Wed Oct 24 09:26:39 EDT 2018 | tech1
Correct, if the Z comes into contact on it's downward stroke during init this can cause the problem you are seeing
