ZWO Errors
Issue #975
closed
1.11 Nightly
ZWO ASI1600mm unexpectedly failing in the middle of a sequence after hours of working great.
Camera settings in NINA are for Gain 200/offset 50, but overridden in the Smart Exposure sequence for 139/21.
USB limit 40
Camera is failing to expose or somehow communicate with NINA during the exposure/saving.
Abridged log attached and specifically captured below.

Thanks Dale. Any additional guidance on where to look for a high quality usb cable, or what traits might make it ‘high quality’? Thanks again!

At the risk of sounding like an advertisement for them, I personally have had success with USB cables from L-Com, who have a wide variety including high-flex and various angled connector species. I’m not aware of such specialty cable vendors outside the US. You may want to look at cables from Tripp-Lite or StarTech as well.

The ZWO SDK is reporting two errors:
ASI_EXP_FAILEDfor exposures, andASI_ERROR_GENERAL_ERRORwhich is a non-specific catch-all status code that the ZWO SDK tends to use when something with the camera has gone awry such as connection issues.NINA’s not at fault here; it’s usually something related to a bad USB connection. Our standard advice here is to use high quality USB cables instead of the ZWO-supplied flat style USB cable, make sure they are under 2m in length, and to secure the cables so that the connectors on the camera are not taking on the mechanical strain if the cables are being pulled by mount movements, such as during a meridian flip.
