Raise temp of nozzle

[appletart76 0]

Can I raise the temp of a nozzle to clean the outside of it?  I don't see anything in the firmware or Cura 3.1 that would allow me to just heat the nozzle.  I am using an UM3

You go to the materials section of the first 'page' of the menu on the printer and click. By click, I mean to push on the lit wheel on the front panel. Then go down to the printcores 1 & 2, click on each one and use set temperature. That will heat the nozzles just fine. I have found that for PVA and PLA that 150°C works well. Enough to soften the gunk on the outside, but not enough to make it burn or dribble filament out of the interior.

I feel silly because I was looking there and I didn't see it then, but I do now.  Thanks!  /facepalm

You are welcome and I think we all have those days when we think 'nozzle', look for 'nozzle' and forget it is part of the core. I know I do!

I think it's easy to miss because there's 2 sets of menus; the Material Menu, and the Print Core menu. You can also use the "Move" option in the Material menu to manually heat it, but you can't control the temperature with that, it will automatically go up to around 200 (varies depending on material installed). Print Core menu is the best option for manually setting it to a specific temperature.
