Reading through the white paper the following can be summarized: 1) A 76 second error is due to the bearings hanging up momentarily 2) A 76 seconds error can't be removed with a PEC curve since it

Pyle PSL92X regulated power supply.? 13.8V @ 5A constant (7A surge).

sorry now all, the first two -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

these all sound like power issues what are you using to power your mount? -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

Hi Michael, What exactly is the detector unit in the Gemini?? I've done work with rotary encoders before and afaik they just use digital GPIO pins. Unfortunately the troubleshooting diagram is only

Hi John they are all equally plausible, which is why you want to run the test i outlined to determine which is at fault. I've read your thoughts about "keeping it at bay" but I really think you are

The encoder theory seems plausible to me. This problem started for me right after I had swapped the outer RA and Dec drive assemblies (outer plate with the two drive gears, gear box, motor, etc. and

Just Warm Restart and continue from where you left off, and that could be any mount position, not just CWD. *** This *right here* is why I say "use Warm Restart!" - even though I *always* park at CWD

THANK YOU PAUL!!!? Perfect description and going to use this as my master config now!!!

Here is a more detailed explanation that agrees with the manual: https://gemini-2.com/hc/index.html *Warm Restart* is meant to be used when nothing's been touched or moved since Gemini was turned off.

For Gemini II, In my experience, the first. ?I suspect the second is just a misprint. By manual, are you referring to the website? JMD

492 units can use 12-18v DC power input you can use the current Losmandy AC/DC 15v power supply, for example Brian

encoder, but it's either wrong or inaccurate. or missing i.e., "still waiting for it to hit that encoder mark"

Thanks, Paul! A you say: a missing cable (like disconnecting it) the gemini says "motor stalled". And that is what I observe. A runaway motor would have to be caused by these: 1. bad optical encoder

Thankfully, that really is how it is programmed. When Gemini doesn't sense movement after applying maximum power to the motor, it will stall pretty quickly. That's what the stall message from Gemini

It was set to cold boot. ?I changed it to “Prompt if not Started”. ?Thanks

Well, not just a diagram, but that process (as shown in the diagram) to isolate where is the root cause :) [email protected]> wrote: -- Brian Brian Valente portfolio brianvalentephotography.com

Yes, that is why we have the troubleshooting diagram, to determine where that may be FYI it does happen in the Gemini, but that's pretty rare -- Brian Brian Valente portfolio

Yes, though the lose connection could be on the circuit board in the motor assembly (or the connector or the cable or the circuit board of the Gemini-2).
