[FR] Resume parked print with m24 without lcd interaction.

[prasadmanjulago]

Is your feature request related to a problem? Please describe.

Hi sorry english is not my main language.

im pausing the print with m125.
And i need parking feature.. so advance parking feature enabled.
After the park, i cannot resume the print without LCD.
M24 doesnt work..

What im trying to do is enabling custom power loss recovery. I have a battery backup.but it cannot hold heat bed and nozzle..

So when a power loss detected , the printer pause the print. Park the head. Turn off heat bed and nozzle.. but doesnt power off steppers. When power comes on it needs to resume the print.. beacuse m125 needs LCD interaction, the print doesnt start.

Parking is must because if not oozed filement destroy the print.and when start the print, some layers will missing beacuse oozed filement..so parking is must .

Is there anywork around to this problem? I need to turn of lcd interaction on resume..

Thanks all..

Marlin\src\gcode\feature\pause\M125.cpp

/*
 *  With an LCD menu:
 *    P<bool>   = Always show a prompt and await a response
 */
void GcodeSuite::M125() {

... // rest of code

  // If possible, show an LCD prompt with the 'P' flag
  const bool show_lcd = TERN0(HAS_MARLINUI_MENU, parser.boolval('P'));

  if (pause_print(retract, park_point, show_lcd, 0)) {
    if (ENABLED(HAS_DISPLAY) || ALL(EMERGENCY_PARSER, HOST_PROMPT_SUPPORT) || !sd_printing || show_lcd) {
      wait_for_confirmation(false, 0);
      resume_print(0, 0, -retract, 0);
    }
  }

Marlin\src\gcode\sd\M24_M25.cpp

void GcodeSuite::M24() {

  #if DGUS_LCD_UI_MKS
    if ((print_job_timer.isPaused() || print_job_timer.isRunning()) && !parser.seen("ST"))
      MKS_resume_print_move();
  #endif

---

if resume_print(0, 0, -retract, 0); is not being utilized, perhaps add it or something like MKS_resume_print_move(); (from M24)
whether or not is true:

if (ENABLED(HAS_DISPLAY) || ALL(EMERGENCY_PARSER, HOST_PROMPT_SUPPORT) || !sd_printing || show_lcd)

so if you can test this try this (in Marlin\src\gcode\sd\M24_M25.cpp):

void GcodeSuite::M125() {
// rest of code

  if (pause_print(retract, park_point, show_lcd, 0)) {
-   if (ENABLED(HAS_DISPLAY) || ALL(EMERGENCY_PARSER, HOST_PROMPT_SUPPORT) || !sd_printing || show_lcd) {
-     wait_for_confirmation(false, 0);
-     resume_print(0, 0, -retract, 0);
-    }
  }


void GcodeSuite::M125() {
// rest of code
  if (pause_print(retract, park_point, show_lcd, 0)) {
+   wait_for_confirmation(false, 0);
+   resume_print(0, 0, -retract, 0);
  }
