DN (Doosan) (S)MX error message: return B-axis

Generates an error message and stops the machine in case B-axis has not been returned to clear chuck and tailstock after resetting the machine. For example: Machine has been stopped with a "B0.-tool" like a Mini-turret close to the jaws with tailstock supporting part. If the operator hasn't manually moved the B-axis to min. B-75., machine will stop and the control will display the error message. N100 (ROUGH TURN); M139 (BED COOLANT OFF); G40 G80 (NEEDS TO BE CANCELED BEFORE G69.1); G69.1; G13.1; G28 U0. V0.; IF[#5004 GT-75. ] THEN #3000=100 (MANUALLY MOVE B-AXIS TO WITHIN B-75. TO B-120.); G0 B-90. (NECESSARY TO CLEAR TAILSTOCK); G28 W0.;
