Why only the E3V3KE? Why not all printers?

Good question! I'm not super familiar with other printer process definitions and for some reason assumed that only the KE used mm values, however, it seems like other printers such as the Elegoo CC do this as well.

If folks would like a PR that changes all printer processes, I could try to whip up a script to do that instead. LMK!

Ah, you are right, and I read this wrong. The profiles for my Voron and Snapmaker both allow for % based line widths. It's the layer height I was thinking of that is a system-wide hard coded mm, and has been requested to allow for a % for quite some time. My apologies! I am surprised to see that the line width unit is apparently a machine-specific issue; and good on you for finding more than one that it applies to!

I think the profiles (processes and filaments) should be rethought, to make them generic and somehow adjust specificities for each machine.
Almost everything can be standardized (as in this case, the line width is converted to a percentage).
The only machine-specific things that I think are:

• Processes
  • Speeds
  • Accelerations
  • Jerk
• Filaments
  • PA (depends a lot on the nozzle size)

I am leaving this comment in case it serves as a starting point for discussion.
