Slewing sounds unhealthy when driver started

kaiyung

@ASIMount@ZWO can you elaborate why the new ASCOM driver would cause these sound and that it would not cause any damage to the mount itself from a large movement? I need to use the new ASCOM driver to fix the known bugs but am afraid of this new issue.

ASIMount@ZWO

kaiyung Confirming with the team.

ASIMount@ZWO

kaiyung It is due to the upper computer regularly reading the info of the mount while slewing, which leads to some differences during the rotation. Will fix this in the next version of the firmware.

mfender can you let know know what the tech support said was the reason for these sound?

Support desk did not name a specific cause.
Here, the phenomena also occurred with version 6.5.11, albeit to a lesser extent.
I'm using firmware 1.1.2.

Edit: I see that ZWO responded to your question... the repeated polling is the cause.
But could it cause a damage? Should we avoid slews with max speed at the moment?

No need to worry.🙂

@ASIMount@ZWO#60768 can the ASCOM team release a quick fix for this bug since it is isolated during a slewing operation?

Ceat

kaiyung This is firmware issue, not ASCOM driver failure. Disturbances are obvious, but stepper motors do not fall out of sync, so I would not worry about it.

Does the new Firmware 1.2.1 solve this issue?

Any comment from ZWO?

Thanks, I will try it!

Has this issue been resolved?
My AM5, which I bought this time, has the same symptoms.
1) It is normal when driving 1 axis
2) Abnormal noise occurs when driving 2 axes simultaneously after removing the hand controller.
3) After installing the hand controller, it is normal when driving 2 axes at the same time.

The latest version of the driver is being used and connection is being used through asiair. Do I really need to connect a hand controller?
