Filament Change Button

[fiveorders]

Dear All is it possible to put a Filament Change Button basically will be a shortcut to M600

I know there are custom commands, but looking for a stand-alone filament change button possibility

Why? What's wrong with custom commands?
You have already the (Un)Load menu that i just perfect for the filament change.

I am having strange behaviours with unload command. first, extruder motor turns very fast for a second and then waits 3-4 seconds and starts to unload. Can you send your marling settings for the filament load-unload process?

Also tried two times, and these lines of error occurred when resuming.

For the moment I can't, I'm at work where I do not have my Marlin, but as I recall I left everything at default speed. Those rapid short movements are not any kind of error, it is made for a better unload of the filament.
