Luiz seemed to experience this problem with the old firmware, trying to get him to clarify.  If so this is puzzling even more.
What is the  last firmware? I am using 2021.04.13

Jennifer:

Did you load the very latest firmware put out there?  

Also your video would not load, said it was a private video.  But I can see from your logs the DEC axis is not responding to the slew commands sometimes.  The axis receives the command, and the command response from the mount is correct but the motor counts are not incrementing.  This is indeed the same issue I saw in Luiz's log file (I was examining your POTH only file).  Something is amiss.

There was a known bug in the dec motor driver which the last updated release fixed.  But honestly it doesn't look like this when one views the log.  This might be something else.  

I know you have a G11.  Are you seeing this in the G11?  I have not, nor did I note it in the EXOS2.  But then again I use computer control and no keypad pressing other than to check for binding after balancing the G11.  PRobably never use it on the Exos2.  

Luiz seemed to experience this problem with the old firmware, trying to get him to clarify.  If so this is puzzling even more.

Wes/Jerry:

It seems I still have the same problem that Luiz has that I thought I resolved.  I created a 20 min video of the behavior of my iExos-100 mount after the FW update and driver update.  Unfortunately, I did not have "trace" enabled on the Misc tab of the ASCOM driver.  I will go through the steps again and upload a log file. 

The link to the YouTube video is https://youtu.be/fhBOTnRAcSw.  At the end of the video I do open up the UFCT and show the splash info for the FW, open the ASCOM driver and show the settings and version, open Stellarium Telescope Control and Remote Sync settings, StellariumScope settings, and NINA telescope settings.  Sorry if that was overkill, but maybe you will see something simple that could possibly solve this issue.

Below is a summary I included in the YouTube description of the issue and software I am using.

Exos-100 Behavior with new FW & ASCOM driver
N & S directions no problem
E & W directions work at first then unresponsive/delayed

Software used:
ASCOM Platform 6.5 SP 1
POTH hub
Stellarium Scope
Stellarium 0.21.0
PHD 2.69dev4
NINA 1.11 nightly #076

Liuz:

We need to rewind and start over.  Your thread listing is very long, and discusses disconnect.  This discussion began long before the latest update firmware.  This is worth noting.  Unless the present issues are different from those you linked to, one can surmise the issue lies somewhere in your particular situation/hardware (computer, cables, PMC8).  If the problem has persisted from the old firmware then you must have a hardware problem (my guess would be a cable).

Please add a signature to your account so we can see your equipment types.

1.  What is your PMC8 mount, an iexos 100 or an exos2?  The tread implies an iexos.

2.  If the issues in the thread are different than yours, please restate the exact issue.

Wes.

Re: Lost control of declination with new firmware #UniversalFirmware

Luiz Sanches
 

When this log was made, what app were you using to control the mount, and what hub did you use?
I ws using POTH, as you recomend (but the old problem that I mentioned in the post https://espmc-eight.groups.io/g/MAIN/topic/iexos_100_disconecting_from/78243484?p=Created,,,20,1,20,0::recentpostdate%2Fsticky,,,20,2,20,78243484&jump=1 never was fixed in POTH or Device Hub, even with the upgrade, only on Generic Hub this mentioned problem dont appear, reason why I all days use Generic Hub)
By any chance do you have your guide camera connected to the mount via the ST4 cable? If this is the case then that is what is causing the problem. The camera signal is being interpreted by the PMC-Eight as driving your mount West and canceling out the motion to the East.
I will try this in the next observing night.
Do you have your Sidereal Rate Fraction (SRF) set to 100 in the ASCOM driver also by any chance?
I never change. 


Re: Lost control of declination with new firmware #UniversalFirmware

Luiz Sanches
 

When this log was made, what app were you using to control the mount, and what hub did you use? 
For control RA and DEC, APT and Cartes Du Ciel or few times, Device Hub. (I prefer Generic Hub than POTH or Device Hub, and, with the new Upgrade, the arrows of Cartes Du Ciel don't work with Device Hub )
Was "continuous track with loss of comms" turned on?
Yes
Do you have an ST4 cable from your guide camera plugged in? 
No, I use PHD 2 with a computer.

Hi Luiz,

Wes has caught me up on your interesting problem. We have been discussing different failure modes that could cause the motor not to move even when issuing the ESTr commands as shown in the log. We came to the conclusion that your problem was impacting the motor driver portion of the firmware and is independent of the command. The driver not only handles changes to motor speed from commands, but also handles changes that come in via the legacy ST4 port which is via the PMC-Eight hardware. By any chance do you have your guide camera connected to the mount via the ST4 cable? If this is the case then that is what is causing the problem. The camera signal is being interpreted by the PMC-Eight as driving your mount West and canceling out the motion to the East. Do you have your Sidereal Rate Fraction (SRF) set to 100 in the ASCOM driver also by any chance?

We will have to go back and consider other failures if you are not using the ST4 cable between your camera and the PMC-Eight.

Thanks, looking forward to your reply.

Luiz:

Jerry and I have discussed this.  We believe your ST4 port  is a possible reason for this lack of response in the RA axis.  Is your Sidereal rate fraction set to 1 in the driver?  Do you have an ST4 cable from your guide camera plugged in?  In any event, please use the UFCT to disable ST4 guiding and see if the issue goes away.

Wes.

Re: Lost control of declination with new firmware #UniversalFirmware

Luiz:

Well the log is helpful.  It does appear that the mount began refusing to track upon command at 10:38:13 and continued to refuse until 10:38:49.  That is a 36 second drop out.  The log indicates the tracking rate command being issued over and over again , the pmc8 responding with the correct response, but the reported position of the mount in RA was not changing.  As for the DEC axis, it seems it responded correctly at all times.  This is from analysis of the log you pointed out had the problem at 10:43.   Interesting.  When this log was made, what app were you using to control the mount, and what hub did you use?  Was "continuous track with loss of comms" turned on?  You did not lose comms though.  I honestly don't know what could cause this.

Re: Doubts about alignment

Jorge
 

Thanks very much Wes. I'll keep trying... and I'll my info.. :) 


Re: Doubts about alignment

Wes Mcdonald
 

Jorge:

Hi, please add your info to your signature.

No, unfortunately when you polar align you must move the mount in azimuth and altitude mechanically, not by using the motors.  This requirement is not related to the pmc8 not remembering motor counts when powered off.  Rather, the polar alignment is done to get the RA axis pointing directly along the earths axis of rotation.  When this is done, rotation of the RA axis does not change the fact it is parallel to the axis.  One can get the scope to point to any point in the sky no matter how the RA axis is aligned...but when the axis is rotated the pointing angle relative to the axis will change, which means the mount cannot track stars.

If you are using the iexos for visual, physical polar alignment need not be very good, rather you can use the virtual alignment provided by the 2-3 star alignment procedure built into Explorestars.  What happens is that during the alignment process,  Explorestars computes a model that tells it how to translate between sidereal coordinates and mount motor counts for all places in the sky, even whn the RA axis is not perfectly aligned.  By using this model Explorestars can find objects, and continually adjusts both the RA and DEC axies to point where the object is at any given time -- this is done when EXplorestars is employing "P" mode, for Point mode.  

Explore Scientific does sell an azimuth adjuster ring which can be added to your iexos.  I bought one, and many others have reported they have on the forum.  It works quite well and allows you to get polar aligned in azimuth easily, at least more easily that without it.

Hope this helps,
Wes.

Doubts about alignment

Jorge
 

Hi all, let me ask the experts a silly question.

I have iEXOS-100 without polar finder nor azimuth adjust adapter, but I have a CCD and I'd like to use sharcap for the alignment.

I can see the polar in the field and it is supposed I have to move the entire tripod to make the azimuth adjustments to align to CP (and the altitude as well . My question is: can I switch on the mount and make the AZ adjustments moving the mount via Cartes du Ciel, p.e., and, once sharcap says it's good or excelent, switch off the mount and switch on again so that the position is reset and being aligned to CP? I know  I have to adjust the altitude manually, but it's frustrating moving the entire tripod to get CP alignment without th AZ adjuster.

Thanks and regards!!

Thank you Jennifer. Last night I had many problems when I was taking photos of jupiter e I needed to move constantly the mount. I will record a video showing the problem.
