Ringing is only present while printing slow.

Any news here?
I have the same problem with a my Y-Axis. It has also 2 motors.

I downgraded to RRF stable branch and upgraded again to unstable, after downgrading did not resolve my problem. I swapped the Y motors to cheap ones I got from omc-stepperonline. It fixed the vibration issue, but unfortunately, I don't know whether It was the Firmware upgrade or switching of motors.

I will investigate this issue further as soon as I have a little more time.

@MaxGyver
thanks
I use also the stepper of stepper-online.
Can you tell me your timing and your motors or the PID tuning of the y axis motor?
Tuning is sadly still not available for double y-axis.

The tuning move only moves the motor by a little over 4 full steps. Is that too much skew for your Y axis to handle? Alternatively, can you set the second motor to zero current while you tune the first one?

I think we got a little missunderstanding. I should describe it better....

´´Axis with > 1 drive will not show´´ so I can´t do a basic tuning in the plug-in.

@IndeX4D thanks for the clarification. If we enable axes having more than one motor in the closed loop plugin, and give you the ability to select which motor to tune, would that be of any use to you?

IndeX4D

@dc42
yes, that would be great.

After a few tests, it seemed to be better when Using different R I D parameters, so I´m positive that a good tuning solve this problem.
Other options may? - wrong Timing? What would you suggest?

Thanks Richard

@IndeX4D tuning one driver of a multi-driver axis is supported in the 3.5beta1 version of the plugin. We hope to release RRF 3.5beta1 later today or tomorrow.
