I think I'll have to get my friends to help with this. They are a lot more knowledgeable how to do hands on stuff than I do.

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.

 


Re: AP V2 driver, move axis command help.

Hi Andy,

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

Subject: [ap-gto] AP V2 driver, move axis command help.

[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!

Re: Serial to ethernet #WiFi

David Diaz <night.skywatcher@...>
 

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 :)

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

Don Anderson
 

It is not likely that the shaft and adapter are actually cross threaded. You would have know if that happened since you would not have been able to thread the shaft all the way in.
It is possible that there was some contamination on the threads of either the shaft or the adapter when you made the connection. Try heating the adapter with boiling water. That may
expand it enough to enable you to tap it loose with the mallet.
Hope this helps

Re: Serial to ethernet #WiFi

Sébastien Doré
 


Hi David,

3 things quickly come to my mind:

- While that’s not a reason for it « not to work », the PoE feature may be useless depending on if your router supports it or not (usually requires a beefy power supply) or if you plan to upgrade to one that supports it in the future. That company sells a similar model without PoE which is likely to be cheaper (I have not checked). Of course, for similar pricing, it is a nice to have.

- They don’t specify environmental operating conditions in the datasheet, so you might want to check with them if it is suited for outdoor (temperature range, high humidity, etc) or at least for likely conditions at your observing place/observatory.

- last, the Ethernet speed supported is 10/100 Mbps ONLY (no 1000 Mbps, ie 1Gbps) so make sure your router supports 10 or 100 (or both) otherwise it will NOT work (the underlying « protocol » is different for each speed).

Clear skies!

Thank you Ray! I installed the version that you linked and all is working well now:)
Strange thing is that the 1200x rate worked fine with my cp4 1100 mount.

I have another issue with Nina and the mach1 but it could be related to the same driver problem. I will test tonight and may start a new thread.


Re: APCC virtual ports #APCC

ap@CaptivePhotons.com
 

Re USBDView - apologies, JoePetrick9, despite you saying "virtual" clearly, I was thinking USB ports, and didn't connect it until I saw Ray's answer.  This tool is worthless for the virtual ports created by APCC.   Save my note for the day you have a USB port/driver issue.   Apologies for the tangent. 


Re: APCC virtual ports #APCC

Ray Gralak
 

Hi Joe,

 

It's hard to say what resulted by disabling the virtual port. If you uninstall APCC it will uninstall the Eltima virtual port driver. Then when reinstalling APCC, make sure to enable the checkbox to install the Eltima virtual driver again. This should put the virtual ports in the default state.

 

Note: the virtual ports that APCC creates only exist while APCC is running, so you won't see them in Device Manager when APCC is not active.

 

And, normally, you won't need to manually create the virtual ports. APCC will automatically allocate appropriate port numbers. And APCC will configure the ASCOM driver if "Auto-Config" is enabled in the AP V2 Driver group box, as shown here:
