Will lowering the first layer height help me or cause issues?

I have a couple of models I've been printing in halves and then gluing together. The resulting seam generally hasn't been too egregious, but it does seem that most of the time the first layer has a very slightly smaller diameter than the layers above, which after gluing the halves together results in a seam that is a slight groove. I'm assuming this is due to the first layer height being set to 0.2 while I'm otherwise printing with a layer height of 0.1, which would logically result in the first layer being less "squished" than the others. All of that leads to my question: Would lowering the first layer height (maybe to 0.1?) help make the seams less detectable, or could trying that cause more trouble than good?

From your description this sounds more like elephant foot compensation than an issue with layer height. Look in the settings for elephant foot compensation and make it smaller (or 0).

Try this first

First try turning off "elephants foot compensation"or adjusting "elephants foot compensation" to a lesser amount such as 0.1 or 0.05.

 

If that doesn't do the trick, You can lower the first layer height, however if you go to a first layer height of 0.1 to 0.05 you will need to re-calibrate your live Z for that.

Topic starter answered:
Thanks!

And each of these near-simultaneous replies are appreciated! This is the first I've read about elephant foot compensation (I'm fairly new to printing). It sounds like I may be dealing with some slight inverted elephant foot! I'll follow that lead. Thanks, all!
