Hy, Bill, Alfred and any interested Losmandy Gemini owners.
I have observed a mathematical error and it's not from KStars / Ekos so you can breath easy Hy. I put my Gemini mini and two motors on a bench test with no computers in sight.
Now this is the setup that was sent back to me with the latest level 6 update, In fact, I believe my Gemini was used in the developing that update, but I was noticing issues while tracking the moon 2 nights ago.
RA tests were all fine with a RA Divisor of 448770 and Dec Divisor of 0
DEC had appeared OK but when I selected Lunar tracking the Dec Divisor was now 23,225,329. This is much slower and with the lightest finger touch on the end of the gear, the motor started to get small shudders and only advance on about one pulse out of three. At the same time the Handbox RA and DEC numbers kept incrementing. It appeared to be normal even though the motor was not advancing reliably.
Ironically, in late June 26 I was critical of Gemini L6 mods as they replaced the absolute lock (or sync) between electrical input and encoder count output with a mod that allowed for uncounted pulses during stall conditions, and there was a complete lack of torque. The July mod has fixed the torque issue but it has not returned the motor to the previous state where it had multiple turns of tolerance (if stalled for some reason) and then return to absolute lock again.
Small steps may be the guide calibration issue. If Hy can please tell me how to increase these steps, I can determine the effect of those larger steps on my calibration.
Thanks
Len
