S50 arm or arm button issue

Ectovito

Hello everyone,

I have a problem with my S50, after a shooting session, the dew shield had to resist a little on the arm and I found the S50 with the arm not closed.
I was able to close it without any problem using the application, but curiously the arm button has always been set to Close arm.
as if the S50 had told the application that it wasn't closed.
I can open it by pointing at an object in the sky without any problem, but now I'm unable to do an EQ set-up, I systematically get a polar alignment error.
What can I do?

I have received feedback on related issues. It is currently recommended to enter the Scenery mode and manually control the joystick to open the arm. I will contact you if there is any update.

Last night I stupidly closed arm without removing dew shield, next thing when I looked at scope the arm was stuck on the flat side agains body.

I used manual joystick and moved it most of way back to where it should be, I then did power cycle and moved it the rest of way by same method. It kept complaining at it was not going anymore but thankfully kept going until it got to its closed position.

I did repot once more to be sure and all was good.

I have the same issue. App is always showing "Close Arm" even when closed. Has a ticket been opened and if so, what is the ticket number?

marvindj I think you only get a ticket if you directly email support, rather than message here.

Via the app, see the tutorial "Report Bug & Log"

I have the same problem now, but the arm was never blocked. Firmware 4.43. The button always shows "close arm", even if the arm is closed. Tried the scenery mode, didn't help. Can't do a EQ-setup. The day before it worked like a charm. today it says alt/az-mode (i never changed from eq-mode) and the s50 can't be switched anymore.
The S50 is only useable in alt/az mode.
i tried:

scenery mode, opening the arm with the joystick and pressing "close arm" -> The arm closes but the button stays as "close arm"
power off the s50 -> didn't help
reset the s50 with the button -> didn't help.

did anybody get a response from zwo?

I appear to have the exact same issue and I have opened a ticket, specifically regarding the fact that EQ Polar alignment fails on what appears to be the second attempt at plate solving. I used seestar alp and saw that the api scope_get_equ_coord returns what appears to be an incorrect DEC value (negated value of my actual latitude). I too had EQ mode working initially, then I switched back to Alt/AZ for a bit. Upon attempting to switch back to EQ mode the polar Alignment failed as described and I then noticed the the "Close" arm button issue (no idea if related).

ZWO placed one append into my ticket which provided no information on the problem.

ZWO support , could you please add a comment to my ticket BT20250417634127S. I'd like to understand current status even if the root cause is still unknown.

Thank you
