Latest Firmware for ASI2600MC Air Incompatible with Celestron AVX Mount

DawgMach1

I have a ZWO ASI2600MC Air controlling a Celestron AVX mount that worked / tracked fine before the latest firmware update. It will no longer polar align or track accurately after the latest firmware update. Errors experienced, during PA when the mount is rotating 60 degrees after the first plate solve, the mount will slow / almost stop, then resume rotating. Once the mount finishes rotating for the 2nd plate solve, the ASI2600MC Air states the mount stopped rotating and errors out. It requires me to perform the PA again, but it always errors out and I can't PA any longer. Additionally, the ASI2600MC Air will not rotate the mount to view objects (i.e. M31 Orion) in the Southern direction. ZWO needs to fix the firmware change that broke the ASI2600MC Air ability to control an AVX mount.

DawgMach1 Hello. Please check whether the power supply/cable of your mount is normal. For example, try changing a cable or powering the mount separately to see if the problem still occurs. If the problem still exists after eliminating the above reasons, please upload the error log to us, thank you.

You can manually do the polar alignment. Stopping during rotation is a common behavior of the AVX mount probably 80-90% of the time, regardless of firmware or software version. I don't think it has anything to do with your firmware.

Disconnect the mount in the settings by sliding the switch to off. Then initiate polar alignment. When you see the dialog about rotation, click skip. Manually rotate about 60 degrees and start the second plate solve. Finish the alignment, manually rotate back to the home position and then reconnect the mount. Do a Quick Align with the HC. Go to preview and move the scope to some clear area of the sky. Plate solve and sync. You should have pretty good GoTo at this point.
