Cura 13.11 - shell-thickness = nozzle-diam.

Recommended Posts

I forgott... I always use a multiple of the Nozzle Diameter for the Shell... (so it's 2.4mm, not 2.5mm)

If this is really a Problem... why not "autoadjust" the Value to the next lower valid Value, which is a multiple of the Nozzle Diameter?? There ale already Values that give YOu Feed Back when a Value is not correct/valid...

If you guys are going to report a bug Daid is more likely to look into it if you provide a screen shot of the layer view that demonstrates the problem along with explaining what you set nozzle size and shell to. If you make a little extra effort, then maybe Daid will also.

This.

You're putting a lot of guess work for me here. You just went from 2.0 mm to 2.4 or 2.5, your problem description is vague ("not working correctly" without telling what "correctly" is in your view)

You're also acting like it's a well known problem, while it's the first I heard about it.

Sorry. I wasn't following this thread.

Here is a screenshot of Cura slicing the 0.4mm calibration box from this thing:

(i have stopped pursuing this routine since it doesn't apply when using Cura)

cura leaving out walls

This should be a box with four walls instead of three.

I used 0.4mm Nozzle diameter and 0.4mm shell thickness.

Here is my complete profile. Just in case you need some other value:
