Anybody tried replacing the brass nuts on the Z lead screws on the A1? The reason is to eliminated backlash in Z. While printing it isn’t much of an issue. However it seems during bed leveling the backlash can cause the first layer to be too low, requiring a global z offset.
Z offset seems to work fine but I can’t help but wonder if the quality of the prints could be better if this Z backlash didn’t exist.
I’ve seen the spring loaded lead screw nuts, but that wouldn’t work in the A1 except to turn them upside down (lose some Z build height).
Anyway I’m going to try a few things because it seems like a very common problem on the A1. But if anyone’s already tried, I’d like to hear how it went.
