Why is my layer height orange?

Recommended Posts

I'm creating a custom printer definition, but there are lots of things about my printer that I don't know, and so I'm starting with a blank template.  When I set my layer height to 0.4mm or larger, the text field turns orange.  Any other value makes the text box white.  So I'm guessing that Cura thinks that 0.4mm layer height is a problem.  I have a few questions:


1. Why does Cura think that 0.4mm is a problem?

2. How can I tell what the minimum and maximum layer heights for my printer are?  I have a Printrbot Simple Makers Kit 1405.

3. How do I specify these limits in the JSON file?

I don't know most of these answers but the orange is because you want a layer height around 20% to 75% of the nozzle diameter.  So I'm guessing somehow it thinks your nozzle diameter is 0.4mm and thinks that 0.4mm layer height is pushing things a bit (the quality will be worse, you will be pushing too much material through the nozzle possibly for the feeder to keep up unless you also slow down the print speed so why not thinner layer and faster print speed for same overall speed and thirdly layer adhesion won't be great).

There is no reason you cannot change min/max value warnings in the definition. In this particular case though, the warning makes a lot of sense: printing with a layerheight of 0.4 or higher using a 0.4 mm nozzle is not going to give you good results.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
