7.7.1 Program Stop and Program End – M00, M01, M02 and M30
To stop a running program temporarily, regardless of the oponal stop switch seng, program: M00
To stop a running program temporarily, but only if the oponal stop switch is on, program: M01
It is OK to program M00 and M01 in MDI mode, but the eect probably won’t be noceable because
normal behavior in MDI mode is to stop aer each line of input.
If a program is stopped by an M00, M01, pressing the Cycle Start buon restarts the program at the
following line of the G-code program.
To end a program, program: M02 or M30. M02 leaves the next line to be executed as the M02 line.
M30 rewinds the G-code le. These commands can have the following eects depending on the
opons chosen on the Congure>Logic dialog:
• Axis osets are set to zero (like G92.2) and origin osets are set to the default (like G54)
• Selected plane is set to XY (like G17)
• Distance mode is set to absolute (like G90)
• Feed rate mode is set to units per minute mode (like G94)
• Feed and speed overrides are set to on (like M48)
• Cuer Compensaon is turned o (like G40)
• The spindle is stopped (like M05)
