Normally I machine these parts in the big old girl, Mori Seiki mv-80 but the lcd replacement for the crt won't be here till tomorrow. So I got 3 of them finished and it worked better than I expected in the Johnford. Then the Johnford issues started to arise. I was drip feeding the program to it, These were the first parts I've ever had to do that to on this machine. All was good until the finish pass on the 4th part. It stopped the spindle and there was nothing on the remote screen. It did throw an error light but no apparent error code. So I rehomed the machine and started it again. It did the same thing, in a different spot, approximately the same x spot but different y. This time it put the emergency stop on, still no codes. I thought it might of had a broken wire for the x stop or something hitting the over travel switch. So I took the cover off and cleaned around the limit switch, everything looked good. I reposted the program to start at the front of the part and tried again to the same result. Then I thought it could be an issue with the dnc/baud rate since I had changed the baud rate to 19200 instead of 2400 or 4800 whatever the old mori is set to. Started the program again with the same result. Then the last time I tried it, the Machine wouldn't move at all. Spindle stopped on the part, machine won't move. Check for error codes and when I tried to restart the nc I got 3 error codes for the toolchanger. Wtf? The program didn't even have a toolchange in it, just one tool. When I tried to start the nc again the tool unclamped for some reason but still wouldn't move the table. Hit the nc button again and the tool clamped again. Then I started to smell something burning. Sure enough a little bit of somke coming from the electrical cabinet. So I quickly shut down the power and opened up the cabinet. The small fuse below the red light was still smoldering. This can't be good.
