Re: AP V2 driver, move axis command help.

I can't speak for the software or drivers, but one thing you said rang a bell -- about it being in the Park 3 position when you are trying this.... have you tried this test looking at a star field far away from Park 3?  If you are pointing at Polaris, East/West movements looks much slower while watching the star field because it's like 100% rotation instead of moving straight across the field.  That wouldn't explain North/South slow speeds though so perhaps this doesn't help.

Re: AP V2 driver, move axis command help.

Sorry I did not have logging enabled. It's the first time that I do this.
I enabled logging and created a new .zip file, attached.

Regarding the move axis, I push the buttons in the client software, not in the driver window.
You are correct. I was pushing north and south with the mount in park 3 position. I then moved the mount east and south and the nudge arrows were working as expected. 

Regarding the duration of the nudge command. It works fine, I saw the driver change from custom rate to sidereal but the dec axis was actually moving sorry for reporting that incorrectly.

It seems that the direction buttons work as expected but the movement speed is much lower than what the driver is showing in the custom rate windows.

Here is the log, I hope that I did this correctly. I never used the log zipper before.
There are no logs in your zip file. Do you have logging enabled?

Ray, I have new information. I set the slew rate to 4 degrees/second. The Driver showed a move rate of 937.3870.
I pushed the north button for a few seconds in the image capture software and I could see the dec axis move. I
would say it was moving a bit faster than 64x, maybe 100x. So it's doing something.

Another curious behavior that I noticed is that even if I kept the north button clicked, the driver would stop the dec
motion after a few seconds.
Here is the log, I hope that I did this correctly. I never used the log zipper before.

Thank you!

Andy,

Where are you pressing the button? In the driver or a third-party application? The driver just issues the commands given to it by the client application. Note that if the scope passed through the Celestial pole (Dec = 90) the Dec direction will appear to change.

One more observation: If I push north, the mount moves north. Then I release the north button and it push it again,
the mount now moves south but the numbers in the driver are the same and they don't change to a negative value
as one would expect to reverse the motion (south in this case).

Andy,

motion after a few seconds.
The driver just sends a rate command to the mount. The driver doesn't issue a stop after a period of time. That may be the ASCOM client doing that, or maybe the mount hit a limit.

Re: AP V2 driver, move axis command help.

Ray Gralak
 

BTW, it can take 3-5 seconds for the mount to spin up to full speed, so the RA/Dec changes will appear slower until the target rate is reached.

Thank you Ray, I tried 1,2, 3 and 4 degrees with both programs and the same thing happens. I see the numbers
change in the driver window but the mount always moves at sidereal rate.

Could it be that the firmware of the mount does not allow any move axis over sidereal speed?

No... Andy, are you physically in front of the mount to verify this?

If so, and you are sure that's what happening, please run the AP V2 Log Zipper utility (it's included with the A-P driver) and zip up the most recent logs and post them here.

Re: Serial to ethernet #WiFi

Tom Blahovici
 

I have used a Silex USB to ethernet server in the past for this purpose. I used a USB to serial adapter to connect to the mount.
The silex seems to be fine for this purpose.  It would even allow my STL11000 to be used over ethernet once the firmware is loaded into the camera with a direct USB connection.

Do you have two strap wrenches?

 

I’d start with those.   Or if you have soft grips on a vice even better for the shaft (not the threads), but that’s less common to have sitting around.  Strap wrenches you can buy at any home improvement store, and are pretty safe (well, don’t slip and drop the bar on your toe, but unlike metal wrenches you won’t mar up the bar with a strap wrench).

 

The problem with heat/cold is that I think both are stainless and probably change together, though it may be worth while freezing all of it really cold, then having boiling water standing by and dunk just the end into the boiling water and very quickly afterwards try turning with the strap wrench.  The idea being to expand just the adapter end.  

 

But frankly I suspect temperature is not going to help, as heat conducts very quickly in steel.

 

You can also try penetrating oil on the threads just so once it moves at all, it will be easier to keep going.

Hi Andy,

I believe that the MoveAxis rate is limited to 999x in firmware. Try using 4 degrees instead.

[Edited Message Follows]

I am having a weird issue with the AP V2 driver. Currently I use the version v5.21.01. The mount is a Mach1
GTOCP3 with the V chip and I am not using the hand controller.
This happens with both SGP and NINA. If I connect the mount and I try to nudge the mount with the direction keys
in either software the mount will not move at the requested speed. I think the software is issuing a move axis
command to the mount. I have the move rate set at 5 degrees per second.

When I push the button I see the custom tracking rate in the driver window change to 1195.7233, that is either in
Dec or RA depending on which button I pushed. However the mount will only move in the requested direction at
the sidereal speed instead of 1195.7233x.
If I move the mount using the buttons in the driver window, then it will move at the correct speed set in the driver
window.

Since this happens with two different programs I think it may be related to the driver, unless I am missing
something?
This has not been an issue so far but now I am unable to use the three point polar alignment routine in NINA
because the mount does not move fast enough between points. It does it at the sidereal rate and that would take
hours.

Maybe there is a setting int he driver that I am unaware of? Any help will be greatly appreciated.
Thank you!

I’m trying to ‘hardwire’ the GTOCP3 to my wireless router so I don’t have to physically connect it to my NUC.  The NUC connects as a LAN and can wirelessly access my focuser and run a VNC wirelessly to my laptop.

If I put the NUC atop my OTA, I’d have to run a USB ‘up’ the OTA from the mount.

I don’t have $1200 for the CP4 upgrade at the moment.

It’s all about the wires, the bane of my existence 🔭😎

Re: Ugghhh cross threaded CW shaft into CW shaft adapter with metal threaded sleeve

Cheng-Yang Tan
 

The adapter (black part) is off so it'll not be marred. The threaded sleeve is stuck onto the CW shaft. I'm worried that I'll mar the exterior threads of the sleeve while trying to get it off.

But in the end, it may be that I'll need to get a new sleeve if I can actually get the sleeve off. 

I'll talk to my friends who actually know how to do this. I don't have too many tools at home because don't want to hurt myself :)

And if you don't want to get the help of a machine shop, a rubber strap wrench and a bench vise with a couple small pieces of plywood in the jaws will probably help you get them apart without marring up the adapter.

When you get them apart, carefully clean the threads of both with a wire brush and a paper towel before re-lubing them and putting them back together.

Hi guys,

As I untwisted the shaft out of the adapter (cursing and swearing + tapping with mallet on a long hex driver inserted into a hole in the adapter), instead of the shaft coming off, the metal sleeve came off with the shaft :(

Any ideas about how I can remove the shaft from the adapter?

And the best part was that I had actually lubed the threads of CW shaft so that I wouldn't do this.

Ugghhh!!!!!

P.S. The good thing is that I still have the old version of the CW adapter and an extra CW shaft, so technically, the AP1100 is still fine.
