As I noted, the mount has operated without any errors over many hours in the past week, so at the moment there is nothing to investigate. Prior to exchanging any of the electronic components, I did

Thank you Bill, for confirming! -Ray

Also, APPM Plate Solve & Sync is working again. 🙂

Hey Ron, That doesn't look like an APPM message (it would say "APPM" in the title of the window). Are you sure it's not from the plate solver? Let me guess... ASTAP?? -Ray

Im' running v1.9.0.7 9.14.21

I'm trying to finally use APPM. (with nina). I updated my license. (106.00 is there sales tax on a license?) anyway. I start the Point model and after the first exposure. I get this error.

The problem may be unbalance in Dec. If not that, then we may have you slightly back off the Dec motor belt tension. That will fix it for sure, but is a bit more involved for you to do. Shoot me an

Your problem has nothing to do with the hand controller. It is just a planetarium program that only sends RA/Dec co-ordinates to the mount when you enter it. Otherwise it is silent and does not

I’m using your 24 V power supply, I redid the test using 600, 1000 and 1800. It is no longer making the noise. If it happens again I’ll contact you.

Roland, I’m using 24v

I'm part of a group at Lowell Observatory tasked with acquiring a new 1 meter-class telescope and instrumentation to replace one of our older research telescopes which is no longer viable to maintain.

Roland, Good topic. Does the ortho model also remain in the CP5 if you send the Mach2 to Home? Is there a way to clear it in cases where I want to use different scopes on the mount but aren’t

We are working on making all keypad modeling available for the CP4. Roland

Hi Roland, will the ortho setting also work with the new keypad software and a older not Mach2 Mount with a GTOCP4 box? Grüsse Konstantin v. Poschinger Hammerichstr. 5 22605

No, the Ortho is always on regardless of whether you use or turn off any of the other keypad models. Once you enter ortho data it stays there until you overwrite it by doing a new ortho

Roland and Ray, Thanks so much for the very detailed answers, I have a much clearer picture of how it all works together now. Your answers address all of my confusion. I think I also understand the

In case you didn't see my previous e-mail: What is your power source? The button rates (xand 1200x) are not the same as the slew rate. The slew rate during a move to Home or to any sky position is

Are you using 12 volt supply or 24? Rolando

My Mach2 to it’s making some strange sounds (vibration) when moving to the Home position. It happens in the dec axis moving counter clockwise (north) for the last 15-20 degrees. It will happen with

Thanks Ray, I ran both as admin and switched to 32 bit and that did the trick. Really appreciate the assist. -- Bill Kowalczyk billk@...
