Danger of collision!
Working with or without M136 means the TNC interprets the
feed rate values differently. Your component may be damaged if
you program excessively high feed rates as a result of this.
If you specifically program M136 before the cycle: The TNC
interprets feed rate values in the cycle in mm/rev
If you specifically do not program M136 before the cycle: The
TNC interprets feed rate values in mm/min
Danger of collision!
If you do not reset the coordinate system after Cycle 880 the
precession angle set by the cycle remains active!
After Cycle 880 remember to program Cycle 801 and reset
the coordinate system
After a program cancellation, program Cycle 801 and reset the
coordinate system
