Re: APCC new install error

Tom Zepf
 
Edited

I should say that as Todd mentioned, I did a completely fresh install of Windows 11 from a USB drive (deleting all disk partitions first so nothing is left). After all these years I've learned that the "start at ground zero" approach is the most reliable / predictable approach, especially with Windows, even if it is a little more work sometimes.

I've been through a few more nights now imaging with APCC, APPM, AP v2 ASCOM driver, NINA, PHD2, ZWO drivers (camera, eaf, efw), Pocket Powerbox Advance, ASCOM, etc and all works as well as it did with Windows 10.

Good luck!

Hi all,

Still in my learning phase using Ascom driver, when i use goto, the mount stops with error message ; Fault Triggered: MotorStall 

Any ideas ? 

Best,

There is no play due to the spring loaded worm. Should feel solid.

You can adjust the tension on the pivot bolt and eliminate the play. Send your request to George at AP and he can forward you the instructions.

Subject: [ap-gto] Mach 2 R.A. Observation and Questions

Folks,
 
I have observed slight ‘play’ in the R.A. axis of Mach 2 Mount.  

Observations:

1. When a slight force is applied to the counter weight shaft or telescope with the clutches locked, there is ‘play’ in the R.A. axis. The behavior is observed when the mount is both powered and unpowered.   Please see attached video of the end of the counter weight shaft that shows the amount of movement when a slight force is applied to the telescope.  I also included a still image showing the overall configuration of the test.

I do not recall observing this behavior before.  I’ve had the mount for about 11 months.

The mount is used at home and often transported to dark sky sites locally.

Questions:

1. Is this considered ‘normal’ behavior?

2.  Will this cause performance problems?

3.  Is there something I can adjust at home to eliminate the movement?

Thoughts from A-P or any other Mach 2 users will be appreciated.  

Thanks for your assistance,

Shawn

Re: APCC new install error

Hi Larry, in may case, upgrading to Windows 11 did not help me. I even tried installing a new copy of Windows 10, then I upgraded to Windows 11 but it still didnt work.
You might try Bill's suggestion first:
"I was late to the thread but SFC and DISM can be used to repair problems with good results normally. That could have prevented the sledgehammer solution."
"Yeah CHKDSK in the event it was fine system corruption may have helped"

If that does not work, installing a new copy of Windows 11 via USB is what worked for me. When I went to select the partition, I left the other partitions in place (did not format them) but I did format the OS partition. Once it was formatted, I selected it to install Windows 11. Once you have it installed, be sure and grab all the updates via Windows update.

Let me know if you have other questions or issues.
best of luck  Larry.

Re: Park Position 1 Warning

M Hambrick
 

Hi Alex

Roland Parks his 175EDF / 1600 mount that stays in his Hawaii observatory in the Park 1 position for the exact same reasons that you describe. Note however that when I was there, I was using only the Keypad to control his mount.  I am not sure how Roland is currently running his mount because it has been a couple of years since I was there. I expect that when he is there himself, he is running the mount from his computer.

I think that Chris' suggestion to create a user defined park position is probably your best option.

Mike


Re: Park Position 1 Warning

Chris White
 

Alex, 

I use a user defined park position as I need to be slightly CW up from the park 5 position.  So, try a custom alt/az if one of the pre defined positions are not working for your situation. 


Re: Park Position 1 Warning

Ray Gralak
 

Hi Alex,

Park 1 is not recommended, so the warning message purposely cannot be disabled. However, no warning message will display if you define a custom Alt/Az Park position.

Due to my sloping roofline in my observatory and that my 1100 is a bit taller than my old mount, the only safe
place to park my mount is in park position 1. My problem is that the ASCOM driver is always warning me
about park position 1. Ticking the box telling it not to show me that warning again doesn’t work. No matter
what I do, I always get that warning, and it’s really starting to annoy me. I actually get this error twice. It
seems to happen when I fire up APCC, and again when the driver is fired up. Is there something wrong with
my config that is causing the no warning option to not persist, or is this a bug?

Re: Mach2 DEC does not slew

Roland/Mike,

With normal connection: E/W moves RA, N/S does not move DEC.
Swap connection at mount: N/S moves RA, E/W does not move DEC.
Swapping RA and DEC cable does not affect anything.

So the mount has some issue?

Re: APCC new install error

Todd, I am having exactly the same issue that you had with the error message.  I have a new Win 10 computer that is only 2 weeks old.  I want to understand what you had to do to upgrade to Win 11 without the issue.  My computer has the option to do a free install of Win 11.  If I did that, is that what you were saying did not fix the problem when you said you had to install via USB?  I would like to have a Christmas miracle.

So how much do you want to bet, that switching the RA/DEC cables shows them to "work" and then reconnecting them back the right way "fixes" the problem?  😁😊😉

Subject: [ap-gto] Mach2 DEC does not slew

My mach2 suddenly developed an issue tonight during imaging. 

I first noticed that something went wrong because SGPro said the meridian flip failed (I have been imaging for a few months and never had any flip issue).

I did some tests and found out that DEC did not slew. RA slewed Ok with AP ASCOM driver and Keypad, however DEC did not.

If I slew to a target or park mount, the mount did not move at all and the light on CP5 turned to yellow. If I moved N/S using an ASCOM or Keypad, there was continuous clicking noise from the mount, it sounded like DEC was jammed or worm teeth got stripped.

Both RA and DEC were well balanced, power seemed good too. Last night's session was good.

Any idea what could be wrong?

Re: Mach2 DEC does not slew

Mike Hanson
 

Hi Yanzhe,

There are several things that could cause your symptoms.  Please run the following test to help isolate the problem:
1) Swap the RA and DEC cable connectors *AT THE MOUNT*.  The yellow LED will remain on, this is OK.  Test N/S and E/W to determine if the problem follows the N/S buttons to the RA axis.  If not, the issue is in the mount.  If the issue follows the N/S buttons to the RA axis, continue on to the next step.
2) Now swap the RA and DEC cable connectors *AT THE CP5* and see if the issue returns to the DEC axis.

Regards,
Mike Hanson
