Comment on 3d printed jig for assembling LED cube layers

Obvs but why the different finish? It should be the same temp and feed rate. It’s weirding me out and I don’t have the ability to image the surface to see the specific difference.

Lower speed between the holes because of low acceleration. Because of this more heat is brought into the layer which makes it more shiny. Your nozzle doesn’t reach the same speed on a 20mm line as it does on a 200mm line.

  Nah it’s moving at the same speed, you don’t see that finish at the edges of the non hole bits where it slowed to turn around.
  
  Has to be a different cause.

You can try monotonic order for top/bottom. Not sure how it works with this many holes, but it usually works amazing for flat surface

  To answer your question, imagine painting wall where you skip some parts and come back later. You can use the same speed and amount of paint, but the lines will be visible
