Very slow camera cooling?

[airscott]

I’ve been having a lot of trouble getting my camera to cool fast enough (always hits timeouts, often gets “stuck” at low cooling power with high temp.

ASI 2600 MM Pro. I can definitely cool the camera to the target temp, as it works just fine in a minute or two in other software. I’ve tried setting Cooldown time to very small #'s and turned firmware cooling both off and on. Not sure what I’m doing wrong but camera always takes 10-20 minutes to reach target temp and often just stops cooling way above the set point with power at low values (40% range).

Suggestions?

I have similar issues with my asi 294mm pro. I never got to the bottom of it and couldn’t reproduce consistently.

What I’ve found to work the most reliably is to not start cooling the camera when voyager starts (this can be set in the camera settings during equipment setup)

Then, at the start of my dragscript I have a cooling routine that has a 5min timeout with 3 retries to get to -20. It might take 5-10min but has worked consistently for several months now.

ASI cooling - has something changed with 2.3.5?

Again about: The Voyager version has nothing to do with it. The cooling management system has been the same for all drivers and has been the same for a decade and does not depend on the camera model/brand. The ramps are performed by setting the temperature and it is a normal thing, it is not a strange, absurd or dangerous operation. This is normal on all ramps and all caeras behave properly. The same ASI brand has hundreds of users in Voyager and only a few report (3-4) this problem …
