Hi,

I am getting alarm #530 Over Travel +Z on my Bridgeport Interact 412. Looking at the attached picture the machine thinks the Z axis is at 16" but in reality the machine is at about 6".I am also including a picture of the controller.

I have cleaned the limit switch and all three plungers associated with it. They operate freely and return to their extended position when depressed.

I am able to jog Z down off the limit, but as soon as I try to go up at all the machine immediately alarms. The result of this is the spindle keeps getting lower, but I cannot jog it up at all. X and Y jog functions work fine.

History on this machine: This is a new install and I was able to successfully run ZRN once, then this problem started.

I am real new to this machine, so it's best not to assume anything. I appreciate any help you can offer.

Thanks in advance

And you posted in THIS forum because you consider a Bridgeport to be a "Benchtop Machine"? I'd really like to see your bench...
