Something to play with in the morning... Printed with 4.8 and horizontal expansion at .02 on the left.  Arachne with line width at .35 on the right.  .4 nozzle at .2 layer height.  Ender 3 Pro.     Measuring thickness - the Arachne print is .65 and the 4.8 print is .91.  It's hard to measure due to the bulbs on the ends of the lines.  The Arachne print has a line missing about 2/3 up and isn't as neat.  That could be the printer's fault as there isn't much material flow
