Hi Rusty, I'm thinking the same thing as Don. Why would you want to use two PCs for this? No reason you can't do it from one and make things much simpler.

Hi Rusty,
Welcome to the SiTech world.  It is so easy to do all that from a single PC or laptpop.  I really doubt you can connect to two PC's with a comm splitter, but you are welcome to try.

Quite A Learning Curve

I have used Mel Bartels stepper motor telescope control system for more than 20 years. I recently decided to upgrade to the SiTech servo motor system. I purchased the motors and electronics about a week ago and have not yet done the physical upgrade to my scope. I am studying the manuals, help files, and currently trying to familiarize myself with the software and everything I need to know to control my telescope with this new system. Do I understand correctly that I can connect two laptops to the same serial port, at the same time, on the SiTech Servo 1 controller using a straight through DB-9 Serial "Y" splitter? The reason I am asking is I would like to run SiTechExe connected to the Servo 1 controller, and control my primary imaging camera with my first laptop, while running my guide scope software (PHD) and sending ASCOM guide commands directly to the Servo 1 Controller from a second computer. Can this be done simultaneously? Thank you for any advice!

Hi Paul,

 

It might be the DEC axis encoder that was not tightened enough and got loose.

It is hidden in the counterweight bar housing under the DEC plate.

I already inspected these parts on my Mesu 200M mk1.

 

We might continue to discuss the issue on the Mesu group or send me a PM as this is not closely related to Sitech Controller.

If the Dec encoder is simply loosened, this is a small issue and easy fix.

Lucas can have a look with you by webcam.

I'm not a Superstitious person, but it did occur to me a few posts back when I mentioned about my MESU 200 that 'nothing had ever gone wrong with it, that it might just be tempting fate.

So today I was doing some daytime tests with the dreaded meridian limits to work out a good eastern limt for my situation, and when I parked the mount, the Dec axis started sounding like a shaken bag of nails. I got the Sitech error

encoder tracking error

And the mount stopped moving which I guess is good.

Anyone got any experience of how to take the beast apart to inspect? There's lots of hex head bolts.....There used to be a MESU 200 forum on Yahoo, I'll see if I can find that too.

thanks,

best wishes

Hi Paul,

Forgive me but just from the outside looking in it sounds like too much of a coincidence that the mount should suddenly develop a problem whilst you were 'working' on it. Generally I don't believe in coincidence. Are you sure you've not accidentally changed a setting related to the motor or encoder? 

I guess you have your config files backed up? If so maybe reload them before looking for a mechanical or electrical problem.

Re: message to all members regarding wiki idea

Just as an update on this, I have the MediaWiki software installed now. I will take a look over the next few days and see what I can find out. I found a basic / beginners tutroial on youtube.

If anyone knows a good mediawiki tutorial which covers creating the user group, setting permissions etc that would be helpful.

Hi Paul, 

I think that's a very interesting suggestion. We have something similar (different format) where I work for technical support issues. I reckon it would need to feature some form of configurable search facility but to answer your question I think your idea has merit.

Hi Don,

As promised I have converted the video to a different format. From the following link you should be able to play it using Windows media player or the Films & TV app in W10. VLC media player is a free app that will play just about any format & is available for MAC or PC.

https://1drv.ms/v/s!AneSiXQRo7prjBRzU_e0UVaJ8I3Z?e=ymEZsK

Alternatively if know which format you prefer I'll try my best to provide it for you.

Best regards

Re: Meridian Flip Settings Explained

MartinC
 

Hi Paul, 
Yes that's it exactly. My observatory is small compared the the scope size. The dew shield is always very close to the dome walls & the shutter threshold is quite high. The difference in dew shield height between starting imaging with weights up/down is approx 1.6m. So if I begin imaging weights up either in the east or the west my scope can't always 'see' over the shutter threshold. That's why I need it to flip on goto's so that I can begin imaging a new target weights down. I'm happy for it to track past the Meridian until I run out of useful sky.

So my criteria are:
I need it to flip on goto's 
I need it to track past both Meridian
I need it to operate with the Meridian in the correct place; not st a Meridian that's been artificially moved to a different place in the sky.

Best wishes

Re: Meridian Flip Settings Explained

Hi Martin, just to show my lack of understanding of this subject, if it's a flipless mount, why do you need it to flip on Goto? What would be the criteria for that? I thought the idea of flipless was you could point at an object rising on the eastern horizon (scope would be pointing east) and you'd just track that right through to the west? I guess your observatory building might be a constraint for that as counterweights go up as you track. I've obviously missed something.

best,
Paul


Re: Meridian Flip Settings Explained

MartinC
 

Hi paul, yes it's very useful. I used it a lot when I was writing my dome driver as you can test during the day as if it were imaging for real.

By the way I've checked my video & that check box is meant to be selected as I need my mount to flip on Goto's.

Best regards
Martin


Re: Meridian Flip Settings Explained

MartinC
 

Hi Paul, 
Many thanks for your comments. I feel you are probably right and I have reached out to Dan.

Regarding the tick box it certainly isn't intentionally ticked, although I have tried both options just for kicks. I'll check the video again. It may be where my mouse was hovering? 

I'll see if can convert the video format so Don can hopefully view it.

Best regards
Martin



Re: Meridian Flip Settings Explained

Hi Martin , at point 3.45 ish in the vid I noticed you have GEM autoflip goto checked. Would it be useful to uncheck this as essentially you don't want flips at all. Just a thought....

I think the ASCOM v2 camera simulator is brill, especially for indoor modelling of situations which were previously taking up precious night time. I have used it for modelling different cameras in SGP with the framing and mosaic wizard to check out FOVs, but what you've shown re loading an image means it's a true simulator, a very clever piece of software, thanks for sharing that.

Re: Meridian Flip Settings Explained

Hi Martin, When I click your link I am presented with a onedrive dialog which looks like it's asking to sign in or create an account, but on looking more closely there is a download button and the downloaded file works fine on my WIN 10 PC.

Regards the problem, I am no expert, but intuitively, if you have limits of some kind, there will be an operational limit/ problem. So I feel you may be back to asking Dan to program in a solution for flipless GEMs

Dan obviously knows the code and how difficult or easy it might be to do this.

best wishes
Paul


Re: Meridian Flip Settings Explained

MartinC
 

Hi Don, 
That's a shame about the video. I'll see what I can do about that.

Basically I'm still having the same problem. It doesn't matter where I place the limits, it just moves the problem to a different place in the sky.

Best regards
Martin

Your video doesn't play on my PC.  So what is your verdict?  Does it work or are you having problems still?  Videos don't help for me.
