Hi Mirko,

To control the mount always use  the flashed fdti cable. Used the same tutorial for flashing the cable.
Regarding the 5 minutes, I managed to do that with a very good PA. Used the PA from ekos tool. Don't forget to download the all the astrometry index files. You need the 64gb on the pi for all the files

Hi Bogdan,

your input is very interesting for me.

Today I’ve made some progress. I updated my EXOS2 to the latest firmware (firmware = 6B09T17AEXOS2) . As a Macuser it was not so easy, but after preparing a Win10 Machine with VirtualBox and the very useful helper tool PMC8_ConnectionManager I got success. 

I’ve used a FT232R USB UART (FTDI Chip) serial cable. After firmware update I switched to serial via terminal on the Raspberry Pi. But than I was not able to connect Kstars/Ekos over serial. With cuteCom on RPi I was not able to switch back to Wifi/TCP.

After this I’ve tried some other options (PMC8_ConnectionManager and P8-Parallax-Serial-Terminal on the virtual Windows machine and CoolTerm on the Mac). It was a little bit confusing, because after ESX! I got never the response ESX1! But never mind, at some point the Wifi connection was back again ☺ So maybe the command works in the background without showin a response.

Which cable do you use for controlling the EXOS2 via RPi4? Is it a normal one or a FTDI Chip cable? 

I found also a thread about flashing the FTDI Chip cable. 

Do you use a flashed cable?

And wow! 5 minutes unguided sounds really good for me. I’ve also made some attempts with QHY Polemaster and RPi4. But at the moment my results are not so good.

Thanks and best regards,
Mirko

Hi all, 

Sorry for the late reply first of all. 
I will reply to the post even people have already provided some answers.

Equipment used.

RASPI 4 with 4GB 64GB storage
Exos2
Main camera Nikon D610/Nikon D3100a
Guiding camera ZWO 120M
GPS module for Location and Time Vk-162 Glonass Navigation Works
Scopes TS420 / William Optics Spacecat

Connection Method
Serial, because reliability and old school using fdti cable.

The story:
I'm mainly a Linux user and also for me was a challenge to switch the mount to serial. You can use the  terminal to connect via serial cable and run the ESX! command to switch to the com mode.
To switch back you will need a normal serial cable not programed fdti serial cable. The issues comes when you want to upgrade the firmware. For that I have an old windows box.
Connectivity to the raspi i do via VNC from laptop because the screen is bigger on the laptop but i monitor all using my tablet. Only the polar alignment and acquisition process start i do it with the laptop.
The PA is working for me only using the guidescope/camera. Via Nikon and main scope I failed.
Good thing is that with EXOS2 and a very good polar alignment I managed to get 5 min unguided at 420 mm . Im quite happy with my choice already recommended the mount to some people.

Bogdan

Hi Bogdan,

that’s very interesting, maybe you can describe some details? After some attempts with "Mac OS only“ I’ve bought a Raspberry Pi (Model 4) and it looks very promising.

How do you connect the Raspberry with the PMC8? Wifi or serial? If serial, how do you switch the PMC8 to serial with the Raspberry Pi via command line?

And it is better to connect the Raspberry Pi via VNC and control KStars/Ekos over VNC? Or do you use a second KStar/Ekos installation which is connect with the Raspberry pi? (As I understood it, this is also possible)

If you could say something about this, that would be nice!

Hi Pavel,

thanks for your answer. I’ve checked minicom, but then the I found „cuteCom“ which has a GUI and for only one command it’s easier than minicom. With my IEXOS 100 it works.

(Not sure anyone answered here)
Just use a serial terminal on your RPi commandline (screen, minicom or
similar) to enter the command to your USB/serial port.

Pavel


Hi Vince,

sorry, that was a little bit unclear written by me.

I used nc (netcat) via terminal and I could change to serial mode with
„ESX!“. But after this, the wifi connection is lost and I don’t know how
to switch back using the RPi4.

Hi Mike,

I am glad you are getting good results with your serial connection. When you go back to the WiFi connection you may want to use the channel selection dongle included with your PMC-Eight to change the WiFi channel on the PMC-Eight. Your local WiFi environment may be interfering with your connection making it drop out. 

Thanks for your kind words, we very much appreciate it.

Jerry,

This is wonderful news.  I have had connection issues with the PMC-Eight wifi since purchasing the Exos-2 a month ago.  I will wait for a bit to try what is on the PDF because with the connx issues in wifi to use the Explorestars app, it forced me to begin to learn APT, plate solving software, connx with Stellarium, and using them all with the Poth Hub and Sharpcap using the serial port.  I am thrilled by the results I have had over serial. Stable rock solid.  It amazes me that when you make a setting change in one program, for instance "Park", it registers in everything connected to the Poth Hub.  Blows my mind, lol.

For one, I truly appreciate your continued support in the forum.  I believe that ES has a terrific product in the Exos-2.  It is my first EQ goto mount and I am enjoying it very much. 

With appreciation,

Mike Forbes

It looks it but its not that back heavy at all. Vid attached. See hiw it just wants to go back to the centre either way.

It looks to me that your rig is very heavy in the rear. So much mass back.   This will cause your dec axis to swing to 90 degrees when the ra is not at 0.  This is what most people want to do but to a controlled extent. Your guide graph shows that you have a lot of dec backlash though which should not be the case if you are very heavy in the rear.
 
The way you correct excessive heaviness in the rear is to slide the rig forward in the saddle.  Not sure you can but that is the cure.  Or add more weight way forward on the tube.
 
What are the rms values for your dec guiding?  If they are in the under 2” sec range then you are going to have round stars mostly, provided you are not getting periodic long excursions.
 
Your guide graph in dec at least does not look that bad....pending the numbers
 
I agree with all the cable management comments. It is most important.  I am redoing all my power and usb wiring now to reduce the number of cables that have to cross the rotating axis.  My current arrangement is a nightmare.

That's great thanks. I might try out the front then.

Its OK atm. It works. Lol.

I have to agree with the various suggestion people have made.  I'll attach a few pictures of my setup.  My concept is to route the cables in a path that has the least amount of motion.  That means keeping them very near the DEC and RA pivot axes.  As you can see in the pictures, I gather all the cables under the OTA and then route them off the front of the dovetail bar and then go to a clamp on the counterweight bar and then to the tripod legs.  This path seems least likely to get snagged on something.  It's the best of what I've found although there may be even better solutions.

I might add that a few months ago I made a DEC axis torsion spring to put a light bias torque on the DEC axis so the stepper only had to work in one direction.  After a lot of work, I wasn't able to show any improvement so I gave up.  But it was a good learning experience.  I even learned how to make torsion springs!
