I have several issues. Going to attack them one at a time. When I connect to the mount and get NINA up and running, I first slew North, the mount slews north. I then press North again and the mount slews south. If I then press South, the mount may move south, or it may move north. There is no pattern. What’s up?
EDIT: When I first slew North, the mount moves north. If I attempt a North slew again, the mount slews south. But if I turn on ‘reverse secondary’ in NINA, the mount operates correctly, until I hit the home command. Then the mount goes back to acting in the original wrong way. If I turn off ‘reverse secondary’ and turn it back on, the mount starts operating correctly. What am I doing wrong?
EDIT: WarpAstron Support says this is normal. Whoever came up with that as being the way it should work should be out having a hard time finding a job.
As our mounts use OnStep system. OnStep will consider NCP as true north in coordinates of GEM mode. So DEC movement near the NCP will be act differently from north of Alt/Az coordinates.
Once mount pointing off the NCP a bit, the direction will be change. Refer to detailed explanations in FAQ of OnStep Wiki, this will not impact normal movement of the mount. https://onstep.groups.io/g/main/wiki/7118
For mount went back and forward like oscillation, it possibly due to AEB protection triggered, as AEB (Automatic Emergency Brake, for collision protection) default threshold could be too low for larger OTA/load, you can follow the AEB tuning guide to adjust this parameter to higher value to avoid this happened.
