Looking for a more dialed in profile for the V400 - can be cura, Ideamaker, or superslicer. The Cura profile that comes with the printer is ok, but leaves allot to be desired, especially in the quality department
Could you please share your pla cura settings for v400 with me, please. I have so much trouble, very dissapointed in my “skills”

I use these settings I got from the V400 community at Flsun V400 Amazing Speed 3D printer Official Group | Facebook.
Vishal is the guy who figured out the settings, and they work really good with either Cura 5.2.2 or Cura 5.3.1. Oh, this system won’t allow me to upload the config file! How do I get it to you? (Or you can visit the v400 community I listed and get it yourself (smile). Cheers, =Ed in Ohio=
