My machine TW-10 is doing something I don't understand. Two days ago, I power it up, started machining and Z0 was shifted 1.5inch (work offset 0, wear takes up to .04", nothing!). There is nobody there to mess around. No other operators, I'm in the middle of long run, program is ready, 300parts already on the table, only run and make adjustments. Today, speed was decreased 50%, for S5000 M3 spindle spins 2510RPM. Same in MDI mode. After reboot, all comes back to normal. Is there somebody with similar problems?? thank You for any answer.
