There are (3) primary spindle M-code commands:

  • M03 commands the spindle to turn in the forward direction.
  • M04 commands the spindle to turn in the reverse direction.
note: You can command the spindle speed with an Snnnn address code, where nnnn specifies the speed in rpm, but overrides from G50, G96, or G97 may apply to the actual spindle speed.
  • M05 commands the spindle to stop.
note: When you command an M05, the control waits for the spindle to stop before the program continues.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
