With the AVX, I experience an issue where if I send an RA slew command and a speed setting of 6, in one direction, the mount will continue to drift in that direction. It looks like a balance issue. Sometimes its east, others west. If I change the slew rate to 3 and then send the command, the drift decreases significantly and eventually stops. So if I am trying to frame and center, I can account for this offset and use a speed of 3 to center. It is a workaround that I am happy with. Now PHD2 sends RA correction pulses which cause the same issue. I can see it in the graph where the RA line is a very jagged, triangle shaped waveform with an error of around 2.5". So it looks like PHD2 sends an RA correction, mount drifts, then sends another correction in the other direction, then the cycle repeats. Does anyone know of a way to change the speed or intensity of the RA pulse commands? Do I lower aggressiveness? I increased hysteresis to 15 and it helps, but I can still the issue occur based on the graph. I've tried east balancing on both sides of the meridian, where I either lower or raise the counter-weight. BTW my payload is about 17lbs and my counter-weight is 17lbs. I first noticed this issue using the stock 12lbs counter-weight all the way down and it prompted me to think well maybe I need more weight on the bar to balance everything out. Tonight looks promising so I am going to work on it some more, with both the 12lbs and 17lbs weights. Note that actual guiding performance doesn't seem to be hurting my images much, but it would be nice to fix this guiding issue. I get OCD sometimes. Thanks!
