1. M00: Program dwell
When CNC executes M00 command, the spindle will stop to rotate,
feed will dwell, cutting oil will stop, it is convenient to size check and
compensate for operator；We can specify the program is dwell or not by
“M00 cancel switch” on the interface.
2. M01: Selective program dwell
M01 is similar to M00；but M01 is controlled by "selective stop"；when
the switch is ON, M01 is effective, program dwell；When the switch is OFF,
then M01 is not effective.
