Connecting the Dome to POTH


I continue to have problems in setting up the POTH rotation.


I have installed the following:

1) ASCOM Platform 6.4 SP1

2) Arduino.ini

3) PDM Dome Setup.exe


When entering the PDM Dome and PDM Shutter I get the following errors:


Rotator Error

Arduino: 1.8.8 (Windows 10), Board: "Arduino/Genuino Uno"


PDMRotator:22:26: error: RotatorClass.h: No such file or directory

compilation terminated.


exit status 1

RotatorClass.h: No such file or directory

This report would have more information with

"Show verbose output during compilation"

option enabled in File -> Preferences.


Shutter Error

Arduino: 1.8.8 (Windows 10), Board: "Arduino/Genuino Uno"

PDMShutter:44:29: error: PDMShutterClass.h: No such file or directory

compilation terminated.

Exit status 1

PDMShutterClass.h: No such file or directory


This report would have more information with

"Show verbose output during compilation"

option enabled in File -> Preferences.


I have confirmed the proper COM port and have attempted to Rotator unit to POTH. I the screen shows that it is connecting, but it never finishes the connection.


Any assistance on or off line would be appreciated.

How do you get error about file that are for the firmware in the ACOM setup/install !?

Can we have some screenshot as none of this sound normal.

You should only need to install PDMDome0523Setup.exe present in the from there :

The other files are for developers and unless you're working on the firmware they are of no use for you.

Also this ASCOM driver only works with version and of the firmware (which is what you should have).

Hi Rodolphe,


I am in no way computer savvy, but am more of a plug and play person. This is probably why I am having so much trouble. I attempted to copy and paste a WORD document to this reply, showing the exact procedure I followed, but the screen shots only came out as small cameras. Is there some way I can send this document to you off-line?

@William Hansen

IF you attach a word document for the screenshot it probably doesn't display as screenshot on the forum but as attached file as word doc are not images. Can you attache the images instead and not put them in a word document ?

Side note : I don't work for NexDome so I don't want to put my email address here as I'm just trying to help. And I don't use Windows with ASCOM but your problem is not yet relate to ASCOM as you haven't even installed the ASCOM driver.

Thanks, I will see what I can do. I am hoping that Babak will assist.

Dec 19, 2018

Ok, hopefully you can post the screenshot here so we can help you.

I will have that tomorrow. The moon looks great!

you say the error refers to a Arduino UNO <----- next dome doesn't use the uno board. It uses the Leonardo boards. check under tools in the arduino software and make sure

it shows (choose) leonardo board and verify your com port. Don't pick the UNO in the list.

best way will be to allow babak or someone (I'd take a try) into your machine with team viewer. its free install it and it will give you a pw. and computer ID. If you share that with someone you trust you can let them in to configure your machine as if they're sitting at your keyboard.

  • This is the process i go through to get to the speed settings for the shutter, so a few questions: First I open ascom dome control panel I click connect. Of course it doesnt let you change values unless its disconnected, so i disconnect and reopen the nexdome ascom server monitoring window, hit setup: Seems no matter what values i put below, here 600/1500 etc, the speed of the shutter is the same. I had tried lowering these at first to see if it would help with the motor sticking. Is this the right procedure to lower the values and test? Also, i know there is a much longer thread here about updating the firmware on the shutter/rotator, but, what does the update firmware button here do? At one point i clicked it when only the rotator was connected, it claimed it updated? How do i know if i even need to update either? Both came brand new recently? Thanks in advance
  • I've completed the motor install (although i may be missing parts on the motor related to this, the set key that holds the pin in place was missing, found an m4 for now that seems to hold it but the pin doesnt go in fully, see this thread for more details) First issue (or maybe not), when i push the motor and it moves up, i think when the panel that has the band through it goes under the first panel, half way up, it sticks for a half second, flexes and pops and keeps going. After this at times on the way up, even during the first half, sometimes the motor stalls briefly. The biggest issue is after its up fully and you bring it down, the first 16" or so going back it stalls and moans repeatedly, however, interestingly i can work it forward by doing an on off real quick multiple times, OR by pressing upward on the motor. Here is a video clip of the stalling (most of it near the end): At this point i took all the wheels off the rear, added washers, so now they have quite a bit of flex available. The retention bracket is installed, but i had my son work the motor while i pulled back on the bracket and wheel on one side only, no change. When you pull the panels in the rear when its up there, apart, you can see grinding marks on each panel on the sides. So at this point i'm left with removing the retention brackets on both sides as a final test, and to be able to get the panels apart to add antifriction tape someone recommended. It appears the front panels will need to come off (not the rear solid non moving one), then apply tape as here: Here is an external view of the situation: This is the antifriction tape i've ordered (1" x 15 feet, two rolls,TapeCase 423-5 UHMW) : I dont know what else to try, other than what i have planned at this point. Pretty frustrated. Incidentally, i have the inside dome rotation working pretty solidly, so this is the only sticking point, pun intended. Thanks in advance.
  • Im breaking my shutter issues into multi parts here, in this one, i seem to be missing the set screw on the part by the gear as in this image: The part circled was naturally coming out. I'd like to get the official part to fix this, however in the meantime i've added what seems to mostly fit but not flush, m4 set screw and the locking pin goes in a tad further: Any suggestions here? From someone else, it appears that pin should slide all the way inside (i dont know if this could be related to the motor stalling/sticking issue i have (sep thread))
