Re: Help with PemPro on G11/Gemini
Hi Bret Wayback is correct the mount needs to be connected before these are populated, but this may be a moot point for you: Use the latest PEMPro 3.0.0.46 and it will automatically set it to 2x cycle

Re: Help with PemPro on G11/Gemini
Hi Bret, What version of Gemini.NET driver are you using? Might be worth a try to update to the latest test version (1.1.10) to see if that makes a difference: https://gemini-2.com/ASCOM.html It looks

Re: Help with PemPro on G11/Gemini
I do not know, but it is certainly a solvable problem. May be the problem is with the ASCOM platform? The dialog is just what you shows, but no clue why the pulldown box is empty. I don't know if this

Re: RA axis movement or wiggle
Interesting, operationally the 3mm movement does not exist.? Push on the DEC shaft let go and it will return to the starting point because the force creates movement by pushing against the worm

Thanks for the clarification. I really thought that the direction of the arrows you see in PHD2 indicated the turning direction of the RA drive. Best wishes, Daniel

That¡¯s about right. There has to be som movement I remember this has been discussed lots before. ?3mm at the end of the shaft is a lot less at the gear -- Brendan

Re: RA axis movement or wiggle
Michael has it correct, you are likely seeing the effects of the spring-loaded worm. It's not a good idea to try to zero it out, that's not how the spring-loaded worms work Roland Christen from AP did

Re: RA axis movement or wiggle
Because it's spring-loaded, you'll see a lot of wiggle if you push moderately hard, but that doesn't mean you have that much backlash during normal tracking.
