The X-axis movement exhibits minor/severe stuttering.
- 2.1 Power is turned off but the Y-axis motor wire is not unplugged, there is a probability of abnormal noise when moving the platform by hands. This is caused by the driver's chip itself.
- 2.2 Transportation collisions cause optical axis deformation.
¶ 3. Troubleshooting and solution
- 3.1 Moving the platform by hands after powering on will eliminate this issue.
- 3.2 Inspect whether the machine has been applied with lubricating grease, and add lubricating grease to the optical shaft.
- 3.3 Remove the optical axis and place it on a smooth platform, check whether the optical axis is deformed.
¶ Please note: Make a correct distinction between stuttering and abnormal noise issues.
- Abnormal Noise: This refers to the unusual sound that persists throughout the printing process. For example, motor abnormal noise, Y-axis linear bearing abnormal noise, Y-axis motion abnormal noise (this issue may occur if the idling speed exceeds 150mm/s), etc.
- Stuttering: The axis moves to a specifica spot and stutters, possibly accompanied by a sound. The easiest way to diagnose this is to unlock the motor and manually move it, where you will feel the stuttering sensation.
