Playing with random seed 137 I rolled gun turrets with 67 range but they won't target biters or nests. I tried messing with target priority and circuit settings but even when they are "working" they don't target anything.
Would any other info be helpful? The only mod setting I changed was the random number seed 137
Full mod list:

Helmod 2.0.17

I tested some code changes locally and was able to fix it by not randomizing "preparing_speed" and "folding_speed" in data-final-fixes. The change to preparing speed prevented the turret from ever targeting anything and the change to folding speed prevented the turret from targeting after it got through its first few shots.

Thank you for the bug report and the fix, I will update the mod on Tuesday.

The issue was, that I have used integer values for the animation speed & rotation speed resulting in a speed of 0. I changed in to float and now it is working fine.
