For chuck-type rotary axis, check,

• Whether the torque of the rotary axis has reduced
• Whether the workpiece is too heavy

If both are normal, then consider the current setting of the drive and the magnetic degradation of the motor; both can lead to insufficient torque of the motor. The current setting of the drive can be set by referring to the dial meter on the drive.

If that does not help, replace the rotary axis with a new, identical one.

For roller-type rotary axis, check,

• The material size
• Weight
• Parallelism of the roller, etc.

If these are normal,

• Access the RDWorks & LightBurn software.
• Enter the user parameters interface and reduce the values of "y Acc" and "Line Shift Speed" (as shown).

 If these have failed, the workpiece may be too light for your type of rotary axis. You might consider using a rotary axis with a compression wheel or a chuck-type rotary axis.
