Regarding cooling, I've had similar results to other with the latest driver release. Cooling is less stable - I've seen +/- 0.4 C variation whereas in the previous release it was close to +/- 0.1 C. I think someone should dust off their control theory textbook(s). Temperature control was solved a long time ago.
Just read my message again - I know EKOS doesn't control the temperature. Apologies if the implication was otherwise. QHY needs to find an engineer who understand this stuff to fix. Probably won't be dealt with until the world get through COVID-19... stay safe everyone.
Mine is a qhy294c running on kstars 3.4.2.
After upgrade to 3.4.2 the temperature control is broken and the temperature would oscilating between 5-6 degree around the set temperature.
Sometimes if it set the temperature to requires 60-70% of 5he cooler power after 10 minutes the temperature would settle. But if I push the cooler to over 80% then the temperature and cooler power just jump around.
If the temperature set at -15 degree, it wont keep the temperature stable
If the temperature is set at -12 degree (rquire abt 63% of the cooler power) then after 10 minutes it would stablize
Please report this to QHY. Thanks for your help and sorry for the broken English
Thank you. Now, how do I revert my libqhy and indi-qhy to the previous version? I search all over the forum and could not seem to find it.
I try the latest firmware on windows via sharpcap and the problem is not there. Seems it only on linux version of the sdk. What a shame!
I have always issue with saved configuration. At the next session, the QHY parameter are not well recovered. Often the offset is 0 when I saved 3. Same for USB trafic. It back to 30 value instead of 0 saved.
Do I have to load a right configuration or is these saved that will be load?
It is automatically loaded by default. Check under ~/.indi and check the values in the QHY config file there.. they correspond to the same ones you expect? Check the permission of the file.. can it be written over by you?
join to this message the QHY183C XML configuration file and a screen capture of the Indi panel just after connection. Curiously, the parameter USB Buffer doesn't exist in the file. The XML .default file, all the value are 30.
