Cura: Nozzle Diameter does not change

[BunnyTJ]

I have changed the nozzle on my Printer but for some reason, CURA does not keep my changed nozzle diameter in the settings. Can someone help me please?

[nallath]

Please use the bug template to report issues. We would like to have things like reproduction steps. How did you change the nozzle size? What do the logs say if you try to do this?

[Ghostkeeper]

Also the version in particular. We've had this issue in the past and have so far claimed that it's fixed in the newest version.

[sorry for my bad english]
Confirmed for Cura 4.3.0 (custom FFF printer)
Monitor->Manage printers->Machine settings->Extruder 1
i try to change "compatible material diameter" but setting always dropping to default "2.85mm"

[BunnyTJ]

I am using Cura 4.3.0 and my diameter keeps jumping back to 0.4.

I am using the Tevo Tornado Profile for my Tevo Tornado Printer. I went into Settings - Printer - Manage Printers... Machine Settings and then I clicked on Extruder 1 and changed Nozzle Size. But as I Ieave and go back in it jumps back to 0.4.

Additional information: Cura 4.3.0 appimage, OS - Ubuntu 17.10
I think, the reason is that i'm using the "4.3.0 appimage" after "3.6.0 appimage". Maybe i should clean up some files or folders before using the new Appimage.
[UPD]
i delete these folders:
~/.cache/cura/
~/.local/share/cura/
Then i create new "custom FFF printer" and the problem is still here. The app just forgot the extruder settings.

I did the same thing with the 4.3.0 AppImage file but it didn't reproduce for me. Here is a recording. (I had to blur out the networked printer list because there are printers there with names that reveal Ultimaker's secrets.)

Hi. This I have done but it keeps jumping back to 0.4 Nozzle size

The same issue Cura 4.3.0 Windows. I can't change nozzle diameter. Preferences->Printers->(Custom Deltabot)->Extruder 1->Nozzle Size
I want to change from 0.5 to 0.4 and it does not work.

@jfima: As a test, can you change it to 0.401?

I checked as you ask. It does not work too. 0.401 0.501 can't save this value

[jfima]

The same issue https://github.com/Ultimaker/Cura/issues/6086 why is it closed? there is a very detailed description and screenshots.

[Ghostkeeper]

Because that issue was fixed back in August. This report is that the issue is back again (though we haven't been able to reproduce the bug yet on this end).

the exact same problem #6505

[ssavickiy]

try using "," or "."when entering a value.

[BorgMcz]

I have the same problem, the board helped change "0.5" to "0,5". The program will correct the "," to "." character after closing the window. And also saves the correct value and remembers it.

[Alex20129]

I checked it in "Cura 4.2.1" twice:
*Normal installation under Windows 10
*AppImage under Ubuntu 17.10
In both cases works normally, setting stored. The problem appears in "Cura 4.3.0" only.

[peterpoetzi]

I can confirm that entering 0.4 does not save while 0,4 does. I am using Cura 4.3.0 under Windows 10, set to German.

[Ghostkeeper]

That explains why we weren't able to reproduce it. We have been testing with an English locale. Good analysis!

I'll put this up for discussion with the team tomorrow.

[BorgMcz]

Hello, Windows 7, Cura 4.3.0, english. The same problem.
Previous version 4.2.1 to it update 4.3.0

[jabss]

Hi,

Same behaviour in Cura for windows 4.4.1.
Workaround of using comma "," instead of dot "." worked.
Anyoing bug. Please fix.

[Ghostkeeper]

This is currently in our backlog, by the way.

[AlexTriada]

4.5.0 - same bug, w10pro

[martan223]

can confirm - 4.5.0 still here

[Phoquounet]

Same issue with Cura 4.5, French language, win10 and with two differents printers profils : alfawise u20 and alfawise u30.

[Phoquounet]

I try to change nozzle size with the value « 0 »
That work (but cura can’t slice, normal) and after I write 0.3 and now cura save it correctly... weird bug

[sergeolkhovik]

Confirming, I have Ukrainian locale on Windows 7 x64, and I had to type "0,5" (comma is decimal separator in UA locale) and it accepted and saved the value.

[NikWas]

Cura 4.6, issue still there. Windows 10, Russian locale, typing the value with comma instead of the dot works.

[mituritsyn]

4.6.1 Same issue with the filament diameter

Try to write « 3 » and save.
After, write « 1.75 » and save

It’s worked for me.

You are my hero 👍

Same problem still exists in 4.7.1
Obviously it has to do with locale settings for using . or , as decimal separator. My region is set to Swedish(Finland), and my win10 display language is english. Changing from . to , in nozzle settings worked. Annoying bug. Hope it can be fixed. I know the same problems can occur in Excel - I've never really understood why this is such a problem. Dot, comma just treat it as the same thing.

Seems fixed on Linux systems

We didn't change anything here, not on purpose anyway, so I think you may just have different region settings now.

but it definetely behave differently. invalid value cannot be entered

[Oximom]

Cura 4.7, win10 same problem. Fixed with changing nozzle diameter to 0 first, save and then set 0,8. It works.

[spawnrider]

Hi,
Same issue in Cura 4.8.0.
you need to use ',' (tip 0,6 with a comma) to set the nozzle size to 0.6.
If you tip 0.6 it will not be saved :(
