Hi id like to know few things, some days ago i started to use nina for the first time and so i have no real experience with it, except this i have a whole fuctional rig, in fact usually my average tracking is below 0.2" as tot error or 0.5/0.6" as rms, even tho im loading 8kgs on a 12.7 kg payload mount, still this aint the issue, ive got the first issues when i tried the 3 star PA and many times it failed to platesolve, i guess it was because dslr gain was too low and even exposure and later on i fixed it, the real issue lies here, when i wanted to go image m1 and sent the pulse to slew and center, nina istantly told me as error arithmethic overflow operation, and if i wouldve ignored me platesolve wouldve told me no stars in field of view, now a thing i noticed yesterday was that i set the wrong camera parameters but it was because tbh wasnt specified very well, no measuring unit asked so i didnt know if it wanted to know pixels in whidt and height or size in mm, however yesterday i fixed this too, now unluckly i its always rainy and cloudy but idk if changing the parameters would allow the pulse to arrive regularly without giving issues, even because if i sent just the pulse from nina to mount to slew it wouldve worked! I'll attach a log abt that session, please let me know, i really have no idea how to get over this. Thats supposed to be the part of the nina log where the issue is: 024-02-21T21:08:14.1196|ERROR|AscomTelescope.cs|SlewToCoordinates|717 ASCOM.DriverException: Overflow di un'operazione aritmetica. ---> System.OverflowException: Overflow di un'operazione aritmetica. in ASCOM.iOptron2017.Telescope.(Boolean ) in ASCOM.iOptron2017.Telescope.SlewToTargetAsync() --- Fine della traccia dello stack dell'eccezione interna --- in ASCOM.DriverAccess.MemberFactory.CheckDotNetExceptions(String memberName, Exception e) in C:\ASCOM Build\Export\ASCOM.DriverAccess\MemberFactory.cs:riga 637 in ASCOM.DriverAccess.MemberFactory.MethodTargetInvocationExceptionHandler(String memberName, Exception e) in C:\ASCOM Build\Export\ASCOM.DriverAccess\MemberFactory.cs:riga 685 in ASCOM.DriverAccess.MemberFactory.CallMember(Int32 memberCode, String memberName, Type[] parameterTypes, Object[] parms) in C:\ASCOM Build\Export\ASCOM.DriverAccess\MemberFactory.cs:riga 421 in ASCOM.DriverAccess.Telescope.SlewToCoordinatesAsync(Double RightAscension, Double Declination) in C:\ASCOM Build\Export\ASCOM.DriverAccess\Telescope.cs:riga 1216 in Castle.DynamicProxy.AbstractInvocation.Proceed() in Castle.DynamicProxy.AbstractInvocation.Proceed() in NINA.Equipment.Equipment.MyTelescope.AscomTelescope.<SlewToCoordinates>d__143.MoveNext() in C:\Projects\nina\NINA.Equipment\Equipment\MyTelescope\AscomTelescope.cs:riga 0

Yes It does, it doesnt have free play in fact, just if i apply a decent force on the ra axis it slightly wobbles, ok then i'll just wait until i get the guide camera and see how the total error is!

Well, if it's like he said then i should adjust the mesh, guess that's the probable issue here

Well idk about this, the clutch always been locked and i knew already those things, however the wobble is there if i put mount in 0 position, 180° or whatever you want, idk if its a maybe loose screw because i don't even know where i should check those, i saw abt cem26 but couldnt find anything for the gem28

Hi, i was able to make the mount work 3 times because i always used to polar align in the wrong way but yea i never had real issues with it, thing is i just noticed this yesterday and so i started concerning i couldve maybe done something, the locking switches are always on and i noticed just with that on otherwise mount head feels steady and smooth, i worry about that because i use an RC ota on it so if i can improve tracking it's always better than leaving it as it Is, still i would like to try check tracking on phd2 but my guide camera didn't arrive yet so i can't do anything of this kind!

Ohhhh my bad, i thought u meant something threaded like worm wheel or so, okok ye i did it because i thought i posted that on a dead part of the forum so i wouldnt get answers so quickly, thanks for the info, however any ideas abt my issue?😅😢

Hi, could you explain better? Im not very handy with goto mounts i never had one before so i don't get what you mean with this

Um, look this mount only tracks if you lock both axis, that's how it's supposed to be, so i don't really believe it's fine if theres the lock switch on and it still wobbles

Hi, i would like to know if somebody knows if i have an issue in the meshing or somewhere else, i never owned any mount like this so i have no experience at all, i started to notice this wobble just yesterday however it happens only if i wanna turn the mount on the left. Please let me know how i can or if i can fix this, i need to sort it out well because i have an RC on it VID_20240208_211805.mp4
