This sounds exactly where I'm at too (i.e., the production SC version works with QHY268C but has the 3-frame buffer issue). Just confirming for debug purposes, if that helps. I tried USB2 last night (instead of USB3) to see if that made a difference in case USB3 length/bus was an issue, but it did not.Jorike wrote: ↑Sun Feb 28, 2021 11:55 am Hi Robin,
Version 3.2.6383 basically works ok apart from the first three shots which is fine, I don't mind waiting, but I'd been resetting because with longer exposures of say 4 mins I'd have to wait 12 mins to see that it was working but because I hadn't I'd keep resetting and starting again only to give up after a while.
