Any ideas

[9mmAuto]

Hi, I’m new to the forum but I have been 3-D printing for about a year now and slowly learning how to tweak my prints and improve them. Today I am printing two models and I have a question about why one of them is missing lines and has gaps, but the other looks good. They are both printing at the same time and I can’t figure out why one looks different than the other.

I'm using an Ender 3 Pro
Cura 4.4.0

0.12mm Layer Height
40mm per second Print speed
210 C nozzle temp

Thanks for any suggestions
Paul.
