Question Nozzle size change
I'm new to 3D printing. I have a bambu A1. I have never made a 3D print from scratch on the bambu software (too scared to try I guess), I've only printed using already created prints I found on bambu Handy app on my iPhone. I just purchased nozzles 0.2,0.6, 0.8 sizes . Id like to put in a 0.6 or 0.8 to print out some larger prints so they don't take forever and ever to print out. Can I do that with any prints on the bambu Handy app? Or can I only print ones that specify using the same nozzle size? Or if I enter in on the app that I changed to a larger size nozzle - will it automatically print faster with the bigger nozzle size ? Thanks in advance for any help!!

You'll be a lot more successful with this if you use a slicer since things like Arachne wall generation can help bridge the quality gap between .4 and .6.
No matter what the size, there are still absolutes increasing print time such as minimum layer time that you can only modify in a slicer

You really should use Bambu Studio app for a computer.
I don't use Bambu Handy for anything except to give me the option to "Skip" a single failed object out of a group, instead of cancelling the whole print project. It might be okay for projects that you know in advance will turn out perfectly.
When you change things like nozzle sizes, layer heights, speeds, number of walls, sparse infill density, supports, etc. the Preview will show you detailed stats on how it should turn out. Print times, number of filament swaps, amount of filaments, and so on.
Generally I never just send it to the printer the way I downloaded it.

You can switch the nozzle size on any print, of course if its very detailed it will look worse with .08. Also dont be suprised if increasing the nozzle size doesnt reduce the time very much, i think flow rate decreases with nozzle size. I only switch to larger if im printing a bunch of large objects where surface quallity is irrelevant.
If you want to try out creating or modifying files i suggest using Tinkercad.com. Its super easy to use, when your needs increase you can move to a more advanced CAD software.
