[FEATURE REQUEST]Extra SD with M20 and M20L

[kleffa]

I see the SD root of my 3d printer with M20 and works!
but if I try use M20L for entire name of files, M23 only works with M20
so I have to chose see entire name of files or comand printer to work blinded

Describe the solution you'd like
I think just asking printer M20 and M20L then show user M20L, but play button with the M20 version, printer send same list so compare both lists should be easy

Describe alternatives you've considered
For now I list M20L so remember position, so change to M20
Additional context

this work to play

this is better for users, but doesnt play

M200 ? https://marlinfw.org/docs/gcode/M200.html ?

Why using M20 but display M20 L ?

Long name worked in past - if now it is not the case, better ask Marlin to fix it instead of ask me to patch not working feature

Here is the answer to M20 and M20L
In esp3d 3.0 beta3 it shows well, but M23 requires short filename. As I can see M20 returns both short and long names.
How it's suppose to worked before?

M21

M20 L

no if you enable long name in Marlin M20 L
then M23 long_name.gcode is supposed to work and I tested before it was working, if now it is again broken(it was several times) it is marlin bug

[kleffa]

in marlin documentation, only shows short name
https://marlinfw.org/docs/gcode/M023.html
also a closed issue of this long ago in marlin
MarlinFirmware/Marlin#3079

so basically it was no a feature and marlin have no intention to work with long names.
maybe a simple solution should be add a button next to play to ask m33 of a short name file

[luc-github]

no Marlin is now supposed to support long name, there were several PR for this

[kleffa]

I can´t find that M23 doesn´t work with long filename... maybe in futrure versions of marlin, but still considering almost easy implement play button for this kind of lines

[luc-github]

you did ot search a lot here one of the PR MarlinFirmware/Marlin#25540

as wrote it is.Marlin bug, I do not plan to workaround because it will not fix ESP3DLib which use shared SD

[kleffa]

maybe just a change on the play button on the webUI, the #define UTF_FILENAME_SUPPORT is not suported universally, requires more memory and that stuff

[luc-github]

UTF is not long name is related to unicode and multibytes chars like chinese

[kleffa]

you did ot search a lot here one of the PR MarlinFirmware/Marlin#25540

as wrote it is.Marlin bug, I do not plan to workaround because it will not fix ESP3DLib which use shared SD

who undestand? I will try that and maybe it get solved, but as I said, not standar answer

[kleffa]

NOP doesn´t worked at all
