[BUG] The abnormal PAUSE behavior

[dupaser]

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

Yes, and the problem still exists.

Bug Description

I am using a BTT SKR PRO V1.2 and a MKS H43 DWIN display. At the moment I have version 2.0.9.5. I have tried using different versions of Marlin, but there is a problem everywhere (somewhere the movement is worked out incorrectly and sometimes the Watchdog is triggered).

When I activate #define DGUS_LCD_UI_MKS and comment //#define ADVANCED_PAUSE_FEATURE : If it is a pause with the M25 command, which is located on the USB Flash, then parking occurs correctly. But if I press the pause button on the display, then a double movement is performed (At the beginning, it goes to the pause point, but then returns to the print area). (i comment out a line queue.exhaust(); in void MKS_pause_print_move(), otherwise, the watchdog is triggered and the board is rebooted).

With St-Link debugging, it is visible that the few next commands are written to the "destination" variable after the coordinates of park position, which is not present when pausing from a USB media.

Good afternoon, thank you for your quick response. I downloaded your archive and configured it according to my parameters. There were issues with building the firmware in DGUS. Everywhere I made changes, I left a comment with the original value and an identifier "332211" so you could easily find them. The main problem was with the name DGUS_SCREEN_MAIN, which I replaced with DGUSLCD_SCREEN_MAIN, and DGUS_SCREEN_STATUS, which I replaced with DGUSLCD_SCREEN_STATUS. As a result, I ran my parameters and observed the same issues I described earlier. If the line is not commented out, the board restarts.

"Changes are only in /mks and in configuration files."

This is solution in void MKS_pause_print_move()

if (nozzle_park_mks.print_pause_start_flag) { queue.exhaust(); }

@dupaser , I'm refactoring the MKS_H43 code when i saw your comment. I've already fixed some bugs and changed some wordings. Could you have a look? https://github.com/narno2202/Marlin/tree/MKS_H43
