Common Mistakes

Using M03 or M04 instead of a number after S.

Forgetting to put a number after S.

The 'S' word sets the spindle speed in RPM. So 'S1200' sets the speed to 1200 RPM.

Common Mistakes

Using M04 instead of M03 for clockwise rotation.

Using S word alone without M03 to start rotation.

M03 starts the spindle rotating clockwise.

Common Mistakes

Putting M03 or M04 after S instead of a number.

Confusing spindle direction with speed setting.

The spindle speed must be a number after S. 'S800 M04' sets the speed to 800 RPM and starts the spindle rotating counterclockwise.

Common Mistakes

Using M03 instead of M04 for counterclockwise.

Forgetting to put a number after S.

S1000 sets speed to 1000 RPM, and M04 starts spindle rotating counterclockwise.

💡 Hint

Common Mistakes

Using M04 instead of M03 for clockwise rotation.

Forgetting M05 to stop the spindle.

S2000 sets speed to 2000 RPM, M03 starts clockwise rotation, and M05 stops the spindle.
