Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Sorry, I didn't realize you can attach a .zip, I've already uploaded it.

A friend told me about making some changes to solve the compilation errors but it still does not appear in the menu and when I execute the M600 command the printer starts the filament change process but I cannot give it to continue inserting the filament later.

• at line 882 of file \Marlin\src\inc\Conditionals_adv.h,
  add HAS_TFT_LVGL_UI

#if ANY(EXTENSIBLE_UI, IS_NEWPANEL, EMERGENCY_PARSER, HAS_ADC_BUTTONS, HAS_DWIN_E3V2, HAS_TFT_LVGL_UI)

• in line 2933 of file \Marlin\src\inc\Conditionals_post.h, add HAS_TFT_LVGL_UI

#if ANY(HAS_MARLINUI_MENU, EXTENSIBLE_UI, DWIN_LCD_PROUI, DWIN_CREALITY_LCD_JYERSUI, HAS_TFT_LVGL_UI) || ALL(EMERGENCY_PARSER, HOST_PROMPT_SUPPORT)

With these options it is not necessary to activate EMERGENCY_PARSER

I still have the problem, I think it is because the ts35 v2.0 device already has its own parking position.
Would there be a way to pause the printing using gcode as if you hit the pause button on the screen?
That would be enough to be able to change the filament.

[Luisdjnas]

I have seen that it does not show the PID menu on the screen either. And you cannot define pause.

No, the TS35 doesn't run separate firmware. The parking position is hard coded in LVGL UI.

I have seen that it does not show the PID menu on the screen either. And you cannot define pause.

Keep in mind that MKS's LVGL UI is a custom UI that does not use many of Marlin's standard methods or config settings. MKS also no longer maintains the UI, so it's on us/the community to fix up various shortcomings.

I started on some of these improvements, but it's a lot of work.

I recommend using TFT_CLASSIC_UI or TFT_COLOR_UI for now since those UIs are well-supported.

Hello, thank you very much for your dedication, if you could help correct errors in the interface I would be delighted.
I hope we can fix the LVGL interface.
I am currently working with the TFT_COLOR_UI interface in which I have modified with help something that I share with you to be able to implement it. The remaining printing time and percentage were not marked.
I have modified

\Marlin\src\lcd\tft\ui_480x320.cpp

y += TERN(HAS_UI_480x272, 36, 44);
// print duration
char buffer1[14];
char buffer2[14];
duration_t elapsed = print_job_timer.duration();
duration_t resto = ui.get_remaining_time();
elapsed.toDigital(buffer1);
resto.toDigital(buffer2);

const uint8_t porcentaje = ui.get_progress_percent();
tft.canvas((TFT_WIDTH - 300) / 2, y, 300, 29);
tft.set_background(COLOR_BACKGROUND);
tft_string.set("|<: ");
tft_string.add(buffer1);
tft_string.add(" ");
tft_string.add(pcttostrpctrj(porcentaje));
tft_string.add(" >|: ");
tft_string.add(buffer2);
tft.add_text(tft_string.center(300), 0, COLOR_PRINT_TIME, tft_string);

I upload the modified file.

This is the final look.
