One of our customers has an old Hitachi Seike HT-25D with a Faunc 11TT control.

The program they are running calls up T0606 (tool 6, offset #6) and runs the part of the program just fine.

Then he calls up T0600 (Cancels tool offset) and instead of the machine just canecling the offset, the turret rotates 360 degrees and goes back to tool #6.

Supposedly this only happens on tool 6.

Any ideas?

Thanks!
