Back button on MK3s+

[joker3d]

Hello, is possiblee to make back button on MK3S+ with MMU2/3? When i click start to print selected item, printer will display "choose extruder 1-5" but... there is only one option how to get back... reset printer.... for me mk3s+ have slow rotation button and sometime missclick and select wrong line. in menu "select extruder" is not possible to go back and choose correct one... Thanks Michal

I second this.
Had exactly the same issue today a couple of time today, eg selected 'cut filament' but accidentally selected the wrong one, one with no filament, there is no way of getting back without reseting. There should be a back/cancel option in addition to retry.

I too want this when I select what fillament to load sometimes I click the wrong one maybe a long press of the knob

I agree most menus need back button, some have them but not all and I have had to hit the "X" button a few times over the years because of miss click or something else.

I don’t think this is very trivial to do with the current infrastructure. But one solution I can see is to add a confirmation dialog e.g. “Load filament 3?” And then “Yes” or “No”

If “No” then show the selection menu again.

It’s very risky IMO to add a back button and allow users to leave the selection menu alltogether, at least in the M600 g-code I’m not sure how to handle that.

A problem with the MMU code is we can’t cancel a load if it has been started. At least not today. So adding a Back/Cancel button there is not possible.

This issue isnt only limited to the MMU Load filament menu… I have experienced it also when selecting a file to print and all the LCD menus.

Yeah a confirmation menu for selecting fillament will do. Please add it
