Re: Problem with first startup of Mach2 -- obstruction / grinding sound

Hi Marty,

I've installed APCC Pro. Daleen was kind enough to resend me the license key. The software is up and
running. I notice that it thought I was using my 1100 and wonder if I still have deleted the earlier data.
The default is 1100, but when you connect APCC should detect the CP5 and set the mount type to Mach2 if you haven't set it already.

And just in case, please make sure you have the latest APCC Pro version (v1.8.8.17)

If not, you should download it from here:

The Dec axis works fine -- no issues. The RA axis hits the stop (sort of a "raspberry" sound) as it starts to move
west from Park 3. Moving east is fine -- only happens when I move west. However, if I then release the
clutches and move the mount, say, 15 degrees further west, it "moves" the point at which the conflict occurs
further along. I've done that repeatedly and can now move the mount from counterweight bar up on one side to
counterweight bar up on the other. I still get the conflict but it is now at a point where I don't plan to send the
mount.

The instruction sheet (welcome letter) that comes with the mount tell you to call the AP office and they will set you up with a license for APCC Pro.

For your stalling problem, please send me your e-mail so I can run you thru a couple of simple tests.

Many thanks. I'll follow the suggestions above.

I did use APCC briefly with my 1100GTO some years ago. Not sure it was this version on this computer, however.

I thought I had already downloaded APCC Pro and didn't notice it was Standard until after this all happened.  Still trying to find out where my copy of APCC Pro is. I got a yellow piece of paper saying APCC Pro is included with the Mach2 but no instructions on how to get the license. I already purchased APCC Standard for this computer and another copy of APCC Pro for my other computer running my other mount (the 1100GTO). I tried purchasing another APCC Pro license for my Mach2 computer (even though it is supposed to be free) and the link sends me to a non-existent page.

Re: Problem with first startup of Mach2 -- obstruction / grinding sound

Ray Gralak
 

Hi Marty,

If you also had a previous A-P mount then the Mach2 is probably hitting limits set up previously for the other mount.

First, uninstall APCC Standard, so you do not accidentally use it again. You should only use APCC Pro with your Mach2.

Next, delete or rename C:\ProgramData\Astro-Physics\APCC\settings.apcc. This will allow APCC to reset all settings, including the limits.

Finally, run APCC Pro again, and it will reconfigure to default settings for your Mach2.

If there are still any issues, then send Roland an email as he requested.

-Ray

I having a problem with my new Mach 2 which was just installed yesterday. I'm using the Ethernet connection,
APCC and TSX. Initialization and connection to TSX went fine. There are absolutely no obstructions in the way
and the mount would swing easily across both axes (until you get to the stops). I believe the GTOCP5 has the
latest firmware (VCP5-P02-08) -- it was updated three weeks ago without a hitch. I'm using v5.30.20 of the
Ascom driver. Running latest versions of Windows 10. All of the data connects appear to be working properly.
The mount is properly balanced. The lines etched into the mount and axes were aligned.

My mount started off in a Park 3 position and I unparked. I tested the movement by selecting objects, slewing
gradually to the west. Initially everything was fine but when the mount was about halfway to the west (about
five hours) it came to an abrupt stop and there was the sound of a mechanical conflict. I commanded a return
to Park 3 (no issues), disconnected and unplugged everything and tried to duplicate those previous
movements manually. There was no issue doing this -- the mount swung easily far to the west and without
obstruction all of the way to Park 4, where I left it. I then tried moving the mount (via APCC/TSX) to the west
from Park 4 and it would not move. Just the sound of the mechanical stop.

The clutches are hand tightened. I first wondered if i had set up the mount incorrectly (reversed the Dec axis)
and that I was encountering the mechanical stop (since it stopped after 5 hours movement) so I checked. The
mount is set up properly. Again, if rotates freely until it hits the mechanical stops, just where you would think
they would be. There is no obstruction at the 5 hours point.

One thing: I thought I was running the latest APCC Pro but it now turns out I was running an older copy of
APCC Standard. (Not sure why). I updated to the latest APCC Standard and reconnected. Same thing -- won't
move to the west from Park 4 and there is a short sound of a mechanical obstruction. Again, from that position
if I loosen the clutches the mount swings freely without noise or obstruction on both axes. The mount is now
sitting approximately in Park 3 and I've disconnected power. I'm finished with troubleshooting for now until I
hear back.

Questions:

1. Have I trashed the mount?
2. What could be going wrong?

Thanks.

Marty

1600GTO absolute encoders

Mike Shade
 

If one were to ship a 1600, first generation back to AP, would you folks be able to do an absolute encoder install on it?  Time needed for that?

Moving from SE Arizona to very rural and dark NM.  Observatory in AZ will be shutdown, the new one is not built in NM.  Great time to send the mount back for an encoder upgrade as mount will be sitting for several months while the new building is built.

Thanks,

Thank you all. Actually most of the time the modeling works perfect, but from time to time I have some very hot nights, with a lot of heat accumulated during the day being released at night (I'm in the middle of the city) which ruins a good percentage of the frames.

Ray I thought APCC already adjusted the model for temperature fluctuations? (and pressure too)
Yes, APCC Pro does adjust the model for the refraction, but not for changes in materials/system flexure. The former can be calculated via a formula, but the latter only interpolated/extrapolated from multiple data models sampled at different temperatures.

Yes, you can load data points from any ".PNT" file. Although APCC does account for refraction changes
due to temperature, pressure, and humidity, there are additional factors affected by temperature, such as the
flexure of the various components. The flexure of most materials will change relative to temperature, becoming
more flexible as temperature rises.

So, you can either create or use a different model, or live with shorter exposure durations with a model
built at a significantly different temperature. In the long term APPM may eventually use multiple PNT file
collected over many months to create a dynamic model that accounts for flexure changes due to temperature.

Re: Large Eagle Hand Knobs

Christine Schmidt
 

Hello Bill,

 

There were two different knobs made in the past.  The current version only uses one of those knobs.

 

Does it use one 8” Extension as part of the pier where it can be on top or the bottom if not needed?

 

Can you send me a picture of the pier so I can be sure it is the correct one? 

 

If it is from the current version, the knob has actually been a point of discussion for us lately.  We are having a hard time getting the same knob in a timely manner.

 

We are switching over to a different know that uses a SHCS and through-hole rather than a blind hole with a set-screw.  We do not have any on the shelf and ready to ship right now.
