Hello fellow machinists, first time user here(love the site).
I have a Vmc with Fanuc oi-mc controls. Running proven program machined just stopped in cycle, came up with alarm number 411 z axis error.
Cleared that alarm, and referenced machine. everything seemed ok. Put into jog mode to double check all axis. When jogging around in x and y machine just jams with a thud (sounds terrible),but it does not do it every time. (lose wire maybe, very confused) any info appreciated.
