New Asiair Plus just keep stopping cooled camera in Autorun mode.

The AAP version I have is like the one at the left side of your picture .

The AsiStudio tests were done using the same 120v to 12v 5A zwo power supply to power the camera.
I'm also using the same zwo USB3 cable (a short one that was supplied with my AM5) same usb3 cable as I used for all my tests done on the AAP, but instead plugged in one of the usb3 ports on my laptop .
It also worth to mention that nothing else were plugged on the camera in all my last tests, and also done all inside ( just taking dark frames for test purpose )
I simply used the same power source and same usb3 cable for both testing methods ( laptop + AsiStudio or AAP and NO mounth EFW , guide scope or else involved, nothing else just the asi533mc Pro involved in all those tests)
When using the AAP, it is powered with another independent 120v to 12v 5A power supply, and the AAP 12v outputs were not used at all.

I will give a try with another usb2 cable like you said and see if it's getting more stable with the AAP.

I will also look to get another better shielded usb3 cable and see if it can help with the AAP.

I will also try to find and test the AAP with another power supply with a bit more voltage, a bit more on the 13v side and see if it changed anything.

I need to be very cautious and I'm taking notes of all different things I'm trying while trying and investigating to solve that issue.

Again thank you for all your inputs, I will make more testing in the next comming days and let you know.

Hi Ben,

I don't think that should matter. But if you have the extra power supply and the time, please try it and come back to post what you find out. It would be a big head scratcher if it mattered!

Good luck.

Ben, I dont trust cheap power supplies because they often do not perform the way they are advertised. If the psu calls for 5a, I buy 10a. A 5a psu will struggle if you consistently push 5amps. How cool are you running your camera btw? I dont use a benchtop supply, maybe oneday. For now I use power plus psu’s power my asi air and my 2600mc runs on the asi air 12v out. My mount runs on a second dedicated power plus psu. These psu’s have never given me issues and are very well built, thick cables and high quality molding. Also these are made in Taiwan.

Swizerlan I agree, 10A should be better.

What is the current output voltage that your getting with a multimeter from that Power supply while unload ?

Also, what's the voltage shown on the AAP on the power and output option page?

I'm just comparing power supply output voltage from you guys that never experienced any cooling instability issue with their cooled cameras also controlled by the AAP.
( my initial goal was to also power my cooled camera through the AAP, but till now it's just a schattered dreams)

Thanks !

BenBret-1 Also, what's the voltage shown on the AAP on the power and output option page?

Even a cheap in-line power meter like this one will give you better, and more information (like average current draw) than what the ASIAIR displays:

https://www.amazon.com/Precision-Analyzer-Consumption-Performance-Backlight/dp/B07RQP6HHN

Amazon has a number of them... I think they are just copycats of one another.

I have crimped on PowerPole adapters at the end of the pigtails of mine, since that is what I use to distribute power. I have three or four of them, since I found them to be more convenient than a multi-meter (that being said, my Fluke 76 has lasted me from the 1990s; the old Flukes are really very solid meters).

By the way, there are also in-line meters of both USB Type A and USB-C varieties. Some of the USB-C ones will actually read out the different USB-C Power Delivery voltages (which can be 5V, 9V, ... etc). It is another thing that will be useful (recall that USB output current from a Raspberry Pi is quite limited).

w7ay Thanks for all those information, I will look at it more closely tonight and see If I can get it fast from Amazon👍

w7ay Just to keep you informed, I've just been able to test my asi533mc pro on another asiair plus.
The ZWO engineer were right the last time they analysed my log files , my 533mc pro is faulty but not the asiair.
My 533mc pro behaved exactly the same way on that other asiair plus and stopped the 533mc Pro cooling while imaging.

Just to confirm that my asiair plus was not also part of that issue, I also tested my AAP with another zwo cooled camera (asi2600mc Pro), and I've been able to succesfully makes an extended Dark frames library without any camera cooling interruption.

I even pushed my asiair plus by powering the asi2600mc pro with one of the asiair 12v output port insted of using my other AC/DC 12v adaptor.
The asi2600mc Pro anti dew heater was also ON during that test which was also draining more power from the AAP 12V output without any instability.
The 2600mc pro was also powering the guide scope camera and the EFW through these two usb2 ports during that stability test. ( camera cooled at -10c)

With that been said, that was a very confusing issue because that 533mc pro camera ran fine without any cooling issues while controlled through my laptop with different imaging softwares ( NINA and AsiStudio), but for some raisons it never ran stable through two differets AAP.

Last update,
I've got another high speed shielded usb3 cable and tried it in the two usb3 available ports on the asiair, but it did not helped or fix the issue.

I removed from the asiair the usb stick and also the micro SD, but the cooling is unfortunately still getting interrupted like I said before, while saving the file now on the eMMc area.

With that been said, I've pretty much tried every thing I can.
I stripped out the asiair completely and only kept the camera attached to the asiair with a usb3 cable, and powering the camera with a dedicated 12v ac/dc adaptor , and the same thing for the asiair ( Did that for all tests done in the last couple days)

In parallel, I opened a ZWO support tickets and sent multiples asiair logs.
I will see what's going to happen next, but I really think there is something wrong with that unit causing that instability issue for the attached cooled camera ( asi533mc Pro ), which is by the way running fine while controlling it through my laptop with asiStudio or NiNA, also using the same usb3 cable and same ac/dc 12v power supply.

I will keep you updated

Last Update
I just received a zwo email regarding the asiair log files i sent, and I was blown away....
According to what they seen in their logs analysis done by their engineers, the asi533mc Pro should be the root cause of that issue and not the asiair.

Really weird .... again i ran the camera last night through my laptop with asiStudio for testing and all went fine.... ???

I'm just hopping their right about the camera instead of the asiair.
I'm just hopping that I will not need to also send the Asiair plus later on too for repair....

BenBret-1 we are following your problem of 533.

Walf@ZWO

Walf@ZWO I sent my two last reports to ZWO Support, one last friday + the last one yesterday evening in reference to my Support ID no. but haven't get any reply from ZWO since last week. ???

Please advise about next steps and how to proceed to get a replacement through the store from where I purchased it, or for à ZWO repair ???

Thank you for your support!

Walf@ZWO How long does it usually takes to get support from zwo and to get a new camera replaced or repaired ? just wondering ?

I have a similar issue with the asi585mc pro in combination with the latest asiair plus. I'm on 2.3 11.56 software.

After shooting 2 or 3 frames in autorun mode it would briefly stop the cooler, then it would start again, but would overshoot the target temp (-10C) and keep cooling. It got to -21 and sometimes at 99% power use.

I'm testing now with a separate power supply as I have also exactly the same experience: connecting everything with my laptop and Asistudio or Nina had no issues whatsoever shooting these darks.

Here I was shooting the first frames

And then suddenly it stops the cooler and the autorun seems to hang also.

No more counter for amount of exposures, no more counter for time.

In Live mode the setup worked fine previously, but I want to take more darks than 20 and work with my own darks library.

Edit: after running into the issue and trying the 2 minute exposures for darks in live mode it also doesn't work.
I got an exposure failed message.

Did a full firmware reset to 9.7 which is of course very low. Then used the v2.2 app to upgrade, but here the mode switching didn't work. Did a full upgrade again to 2.3 and 11.56 and now it's working. Very weird.
