Well this makes a lot of sense. Thanks Chris.

Why not?

Nope. CPx controllers (that aren't connected to Abs axis encoders) have no way to know when they are moved between mounts and they always assume the worm gear and wheel positions they currently have

Simpli no! Grüsse Konstantin v. Poschinger Hammerichstr. 5 22605 Hamburg 040/8805747 0171/1983476

But if the mount isn't moving at all when it's connected, wouldn't it query to figure out the current position?

No. CPx controllers always know the worm gear positions of both axes by saving them to NV memory just before losing power when power is disconnected. A freshly-connected CPx controller has no idea

Wouldn't the new box know that once it's powered on and connected to the motors?

Howard, thank you for speaking to me on the phone today. For the benefit of others, I will repeat what you told me to do to attempt to solve the problem. Park the mount (I used Park 3) Reconfigure

I don't agree. Changing CPx controllers requires that a new PEM recording takes place. There is no way for a new CPx controller to know where the old CPx controller left the worm gear positions

Hi, just to let people know that Roland and Team (yes, with a capital T, they deserve it !) are kindly working with me in the background on this, which is why the thread has gone silent. Quadruple 'A'

For those interested, I spoke with Dave today and as long as the mount doesn't move it is OK to download your PEC curve, change CP's and then upload that curve to the new unit.

Hey Wade I’m not in Rusty’s. But I see him a couple times a week. So I will. Are you back near Ellensburg, do I have that right? I know I was supposed to come by sometime this summer, but the

Hi Max, Please zip and email me a log file that shows this.

Make sure all your cables are plugged in and the encoder lights are green or blue. Check the encoder cable inside the Dec axis to make sure it is seated. Roland

Well I disagree with always using apcc to do a park. In Voyager if you are done for the night it should park where you have set the park. If you are automating everything, the final step will be to

Actually, I think that this is something to do with Voyager. Perhaps a new release. When I am done at night, i select point at zenith in Voyager. It is not park. Then I stop tracking in Voyager. Last

You need a remote controlled umbrella. British style, big and boisterous. Rolando

Are you at Rusty’s by chance? If so, say hi to Dennis and Dianne for me. Regarding the time zone issue, if your computer is 100% dedicated to the observatory, you might consider setting it up on

Come to think of it, and I forgotten until you mentioned it, NINA asks whether to sync ‘NINA to mount’ or ‘mount to NINA’ . And I know I chose ‘NINA to mount’. I guess it should be the

I honestly can't explain why there's a difference between an external app such as NINA telling the driver to park, and the driver's own park button giving different results. I would think that both
