A few weeks back my HIT-18S lathe died. I was running a new part and I had the Z clearance set to Z10. and with a long tool it backed up too far and I got the dreaded "z-axis contouring" error. Now the only way I know out of that error is to power off and back on. When I powered it back on I got an error 43 "PLC-CPU not ready for operation"
Short version, With the help of 2 very good friends we found a dead power supply on the back of the front panel keyboard, dual 5.1VDC. Could not fix the Siemens supply, so we put in 2 separate supplies mounted on a custom made Plexiglas mount. THEN....after a full day of muddling thru a whole ton of new errors we got the correct boot up procedure to restore all the files. Somewhere in there we did a NC general reset, which wiped out all the stored settings, but all is well now.
Just trying to post something ON topic.
