Disabling DFS on K-7

botiapa · 09-28-2022, 12:13 PM

I'm trying to disable on DFS (dark frame substraction) on exposures longer than 30s and been following a guide, but I simply can't figure out why it doesn't work. Here's what I tried:

- Copy MODSET.474 file to SD card root
- Copy SYSPARAM.txt file to SD card with [DISABLENR] and when that didn't work, I tried [DISABLE_BULB_ALG]

I could successfully enable, and get into the debug mode, but DFS still ran. (40s exposure took around 80s)

I then downgraded the firmware to the very first version, 1.01 tried the same things again, but it still didn't work.

Let me answer my own question, I've finally managed to figure it out. The key was that both DISABLENR and DISABLE_BULB_ALG are needed. It even works with the newest firmware, however debug mode does need to be enabled for this to work. If anyone needs help doing this, don't hesitate to contact me.

Glad you resolved it.
