Tune icon in LCD
Hello,
I am having the Prusa Mini+ for 2 days and the prints come out perfect so far.
I have a few questions though.
1. What is the Tune Icon does /mean when I print?
How can I access its submenu if it has any?
I am asking because I cannot select it with the knob.
2. In the LCD menu under Settings there are Temperature, Nozzle, Heatbed and so on.
Are these to put different temperatures than the default ones that are in the settings of the ready to print files?
And how do they work?
If I put 10 in the Nozzle setting will add 10 degrees for example?
Sorry if the questions sound silly but I am new to 3D printing and I have no experience whatsoever.
Also I searched the forum for these and I didn't find any answer.
Thank you in advance.
RE: Tune icon in LCD
The answer to 1) is you just highlight it and press the knob. I think it will only work when actually printing, or if you are using something that controls your printer like Octoprint. The purpose of the tuning section is to let you adjust things like the Z height and bed/nozzle temperature whilst printing. You can also trigger changing filament from here (this doesn't seem to work if you are using Octoprint, but don't worry you aren't!).
You might want to use Tune to tweak your Z height if you are printing something with a different filament to the one you calibrated your first layer with, and see signs on the first layer that it is too high (isn't squishing properly to the bed) or too low (it looks like it isn't smooth and the nozzle is tearing into filament you have already laid down and making it look rough).
You might also want to adjust the temperature in rare circumstances, again where you feel something about your print is failing but a higher temperature might save it. This will come with experience.
2) These settings do not override Gcode, they are for changing the actual current temperatures. You actually can't access these whilst printing. They are not an offset, they are actual values. If you set the nozzle to 215 in that menu, it will start to heat up to 215 right there and then. The same with the bed. Usually you won't go into this menu, but if you think your nozzle is clogged you might go here to set the nozzle temperature to a very high 280, wait 5 minutes for the clog to ooze out, and then go into the Axis menu and manually extrude some filament to be sure, then cool it all down when you are happy.
I hope this helps!

Thanks for your help Robee.
Yesterday I realized that everything is controlled in the Slicer apps and exports as gcode.
So every setting is included already and you cannot alter it in the printer.
I am still at the very beginning.
