<p>But, if you created a new printer profile, that option is not available. This is because that option is not available in custom print profiles. In order to use that option, the printer profile requires a variants configuration option; e.g. <code>&quot;variants_name&quot;: &quot;Nozzle Size&quot;</code> for the Ender 3 profile and for Ultimaker printers that is <code>&quot;variants_name&quot;: &quot;Print core&quot;</code> as they use a printer nozzle core concept.

<p>The nozzle diameter is part of the printer configuration, but, linked to the <strong>Line Width</strong> property. You therefor can set the line width to 1 mm to achieve the same. With respect to the nozzle diameter, it is also found for the custom printer layout using the following: with reference to version 4.13.0, the nozzle diameter is set in the machine setup. From the main menu go to <strong>Settings</strong>-&gt;<strong>Printer</strong>-&gt;<strong>Manage Printers...</strong>. Now select your printer (and activate it to be able to) select <strong>Machine Settings</strong> and go to the extruder tab sheet to change the nozzle diameter (option <strong>Nozzle size</strong> under nozzle settings).</p>

This is valid for the Ender 3 profile, but when you have created a new printer, the nozzle size option is not available! (This is buried in the printer settings...) Basically, this answer is valid for the Ender 3 profile, not for a custom profile as the OP questioned. So, either redirect the OP back to the Ender 3 profile or add a section to cover custom FDM printer settings. I've linked my answer to your answer explaining it is valid for an Ender 3 profile, you might want to do that in your answer to improve it.

<p>I just upgraded the nozzle (to 1 mm) on an Ender 3v2 and want to make a test print.  I added a new printer for the new nozzle size.... and can't find a setting for it.

Consider moving to a more competent / modern slicer.

Also, yes, nozzle diameter is irrelevant, only line width matters.

@towe Please clarify what is not competent/modern about Cura (e.g. they release updates very often) and which slicer do you think is better and why? As the comment stands now it could be considered inflammatory, it is an opinion. Personally, I've used and am using different slicers for different machines, my opinion, is that I do not think that Cura is not modern or not competent. :-) It is however sometimes difficult to understand the settings and the material profiles, so in that respect I can imagine there is room for improvement! ;-)

> Where can I change the nozzle diameter in Cura?

The best way forward is to go back to the Creality Ender 3 print profile, if so, you can use [this answer](https://3dprinting.stackexchange.com/a/19401/). So, you can select the correct nozzle size instantly.

[![Ender 3 profile nozzle selection](https://i.sstatic.net/q04bU.png "Ender 3 profile nozzle selection")](https://i.sstatic.net/q04bU.png "Ender 3 profile nozzle selection")

> Why is mine missing?

But, if you created a new printer profile, that option is not available. This is because that option is not available in custom print profiles. In order to use that option, the printer profile requires a variants configuration option; e.g. `"variants_name": "Nozzle Size"` for the Ender 3 profile and for Ultimaker printers that is `"variants_name": "Print core"` as they use a printer nozzle core concept. In order to use "variants", the printer profile needs to be aware that variants are available (from the Cura wiki as linked below):
