I hope there is some simple answer to this!
I recently received a brand new EQ6-R Pro and have been shaking it down prior to putting it to real use. Initially, I had a gross pointing accuracy problem (see: https://www.cloudyni...lignment-issue/) and only just today thought I had the problem solved. This solution involved updating the SynScan firmware from v4.39.12 to v4.39.21, and the motor controller firmware from v3.9.23 to v3.25.
I was initially delighted with the results. The mount slewed to many targets using the handbox, and both the handbox and ASCOM showed identical pointing results (something that wasn't happening before). This was working for at least 2 hours, but now, without changing anything I am unable to get the mount to slew at all. The motors give a whining sound for a few seconds and then stop. I have switched off the mount and restarted it several times to no avail. I have tried a factory reset, again to no avail. The power LED keeps flashing.
I would appreciate any help you can offer.
