Terry:

Have you changed the slew rate to 2.5 in POTH before attempting to use the directional buttons?  If you did not that could explain why the mount is not moving.

Can’t say why poth won’t stop but the hub works fine.   There was an issue long ago but that is corrected now

Sorry to hear that Andreas, if I find a solution I'll post it here, I have changed everything over to use Device Hub instead of POTH, hopefully it will work but reports from more experienced users suggest that it won't
Failing a solution I'll have a virtually new 200 PDS for sale, used once only,  I'll go back to a simpler/smaller set up AZ-GTi, ASIair pro and mirrorless camera with manual lenses

Mount: ES PMC-8 EXOS2, ioptron SkyGuider Pro
Scope: SkyWatcher Explorer 150/750 PDS
Cameras: Canon 6D, Canon 7D Mk2
Guiding: ZWO ASI120Mini mono, ZWO 30F4 Guidescope, PHD2
Msc: TS Optics Coma Reducer Corrector 0.95x
Software: N.I.N.A, APT, Pixinsight, DeepSkyStacker, Photoshop

Still haven't managed to get POTH motion controls to work fully, the stop button does nothing so the only way to prevent the mount from continuously moving is to hit the park button, obviously that's not going to be practical
I have uninstalled and re-installed the PMC8 drivers as well as Ascom
The Ascom device hub seems to work fine but I'm led to believe there are problems using that with the PMC-eight mounts?

Failing that I have to assume there's some kind of issue with my laptop, I wish the set up was much simpler, it's enough to wrap my head around astro imaging when everything is simple without all the extra brain strain from functionality problems

I'm getting to the point where I just want to sell it all and give up now and just go back to a simple AZ-GTi with DSLR/Mirrorless se up, so much easier with Sky-Watcher's wireless arrangement

I don’t know if it’s compatible, but there are several options. You could use polar alignment in NINA. Also, if you have room at the end of your vixen rail, there is an adapter for the PF camera that will mount under the rail.

 Good luck.

Hi Steve, I see time ago 3D adapters on Thingiverse but the problem with that adapters is the need of other QHY adapter.

The ADM adapter is great!!!!! but having the PolarFinder adapter from Explore Scientific for my iExos100 would be great if you could screw the Polemaster directly onto the adapter.

Hi guys, I want to know if the PolarFinder adapter is compatible with Polemaster. I have the PolarFinder and i thinking to buy a Polemaster but the iExos100 does not have official QHY adapter.

Thank you and kind regards.

--Re-installing Explorestars hasn't helped but at least I can use it on my android tablet if I just want observation or unguided short exposure imaging
My big problem now is POTH motion controls, N.E.S.W. work fine but the stop button in the middle of them doesn't do anything, that's going to make it useless for alignment on targets to sync

Any ideas folks?

Yes I had installed the Ascom drivers from the update kit, a nice clean install as this machine has not had Ascom installed previously, so it's a fresh install of Ascom 6.5 with POTH and then the pmc-eight drivers

It's doing my head in now, I going to try different usb ports next

Ram:

The cheapest option is to replace the Losmandy dovetail on the scope with a long Vixen dovetail.

The next mid-range price option is and ADM D to V converter that fits into your existing Vixen saddle that coverts Vixen to Losmandy.

The most expensive option is to replace the Vixen assembly on the mount with an ADM DV assembly which would give you access to both Vixen and Losmandy connections.  This option is requires some technical skill because you have to remove the DEC motor along with the Vixen assembly. The ADM replacement does require drilling or filing to widen the slot to remount the DEC motor in order to use the existing bolts.  

I chose the last option because I personally do not trust saddle connections that use screws for a large scope.
It is all a matter of preference.

Hi folks
I thought I'd finally have a go at updating my EXOS II to the latest firmware but now I'm struggling
At the same time I wanted to install the software onto a different laptop

I followed the instructions in the PDF file with the firmware installation kit (PMC-Eight 20A01 Firmware Installation Kit 2021-08-08)
It seemed to update the firmware, I got the success message in the config tool
I went on to install Ascom 6.5 with POTH and tried to use POTH to slew the scope but nothing happened (Unparked and set to track first of course)
I installed the Explorestars app and data but on launching it just say's "Please Wait"

Certainly I've done something wrong but can't figure out what?

Thanks
Terry
