I have just been outside and as suggested pointed the OTA to the west (telescope at the East of the tripod) and experienced the same departures as described in my contributions to this forum. I then pointed the OTA to the East (telescope at the West of the tripod) and to the departures on the RA channel continued but worse with fair amount of cross-talk to the DEC during peaks. I have 9 Kg counterweights at 16cm to balance an Askar SQA106 and 2600MM Air, EAF CAA and EFW. Connected the AM5N via Bluetooth and USB cable, no difference. tried 0.25X and 0.50 Sideral from 25% to 50% Aggr, no difference. 1000ms calibration step and 500ms, Darks and Gain selected at 250 and 350, no difference. Checked belt tension and both motors have good feel. Commanding movement on RA or DEC happens without jumping teeth as far as I can tell. Firmware is 1.7.7. Mount directly and independent powered by 60W 12V supply. 2600MM Air, CAA, EAF, EFW powered separately by its own 72W 12V supply. Tripod confirmed level prior session, seating firmily on concrete slabs without movement. PA completed twice and twice confirmed deviation below 15" on RA and DEC before staring session. No cable snags or dragging. All USB cables checked before installation working flawlessly.
Changed the Askar SQA106 in its entirety to the iOptron CEM40 EC next to the AM5N and after PA and PHD2 calibration, guiding below 0.50".
The above strongly suggest that IT IS THE AM5N MOUNT...!!!!
All subs tonight look like this:
Despite promises from ASIMount-ZWO that ying.tang@zwoptical.com was going to contact me very soon, two weeks have passed without anybody from ZWO Support contacting me in any way or capacity. I have been completely and totally abandoned with a faulty mount that does not perform as advertised.
