Hello, I'm currently building my first "large" CNC machine and I have stumbled upon my first problem which manifests itself as high pitched whine when motors are idle/stationary, I'm using LinuxCNC to control the motors.
Is the high pitched noise normal for TB6560 driver? Noise can be heard in the included video.
I'm using:
- 3X NEMA23 270oz"in 3A motors
- TB6560 driver
- 24V 15A PSU
TB6560 config:
- Current 75%
- Decay FAST
- Micro stepping 1/2
Cheers!
I searched the forums before posting this and I think that its caused by PWM but not sure.
