good to hear, Someone had the same issue and my advice helped. Meanwhile I had an other discussion with Chen w7ay and he gave me a hint for an easier work around.
when error shows in calibration (or totally slow data update in guiding view), just:
1) stop guiding
2) goto mount menue and disconnect mount.
3) reconnect mount in menue
4) sync mount in mount menue
this will solve the problem without unplugging the usb cable and a new repositioning with plate solve. Makes it easier and more comfortable as Long as ZWO is not solving the bug.
