keep getting 211 OT -X alarm randomly every so often. Is there some type of sensor under the turret that could be throwing it off or maybe something to do with the index tools. I am also having issues with the turret not wanting to rotate and in turn not zeroing out unless I trip an interlock and pretty much trip the light. I'm not familiar with this machine and it's been years since I've had any dealings with a CNC and our maintenance basically says restart restart restart like it's going to magically fix itself. Any help would be appreciated because I have to be over thinking this it just seems like a simple issue.
