This evening I had a problem that I have never had before with the 1995 5020Fadal. I had a tool change that failed. (page 43 says that the ATC has failed) The ATC picked up the tool from the spindle but did not advance to the next tool so the ATC retreated to HOME position and closed. I now have a tool in the holder where it needs to be empty. I know how to fix this with a HAAS but for the life of me I can't get the ATC to stop with the door open before it crashes into the spindle.
I could not tell yet if there are any other problems. It has been running really well for the whole 12 hours today and in fact all last week also. What caused this problem I am not sure until I can get the ATC unloaded and do some testing. I did not see the failure as I was running another machine across the room. I just noticed that the 5020 was not machining, there was no crash or anything
Suggestions are welcome and appreciated.
