Does Cura 2.3 support single-layer thin walls?

[KDeus 0]

I've created a model with its own custom supports, and I created the support walls to be a single layer wide (ie. just over 0.4mm, for a 0.4mm nozzle). But when I print this using Cura 15.04.6, the support walls are printed in two passes, so they're 2 layers wide (0.8mm).

Is the same true of Cura 2? Or does Cura 2 support single-width walls?

Are you sure its not just making a single print pass and then a travel pass over it?

Have you check the Layer view in Cura to see if it is a single wall or not?

Do you have any calipers to put on the wall to see exactly how thick it is?

Cura 15.04.4

Cura 2.3 (Release)

I've printed single wall items in both versions of Cura and not seen what you are experiencing. Perhaps there is a setting that's not right.

It's definitely not just a single pass + travel pass. My calipers measure the support walls to be 0.8 to 0.9mm.

I've imported a test model into Cura 15.04.6. Here's the result (and you can see the original model from Fusion 360 in the background):

The widths in the original model are 0.21mm, 0.41mm, 0.61mm, 0.81mm, 1.01mm.

Here's the result from printing the model. It's a little hard to tell from the picture, but you can see it printed 2 lines side by side, even on the thinnest part:

The thinnest part of the model that printed is between 0.8 and 0.9mm:

This is the profile I'm using: TestPrintSettings.ini

Just to follow up, I installed Cura 2.3, imported the same model, and printed it. The thinnest wall on the new print appears to be a single pass. The measured width is more like 0.5 - 0.6mm, which is hopefully small enough that the supports can be pulled away easily.
