[BUG] Pause and Stop buttons causes crash on Anycubic i3 Mega #26900

Open usonic777 opened 3 months ago

usonic777 commented 3 months ago

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

Yes, and the problem still exists.

Bug Description

After clicking Pause on the touchscreen, printer resets.

I am using Anycubic i3 Mega config from config/examples directory.

Bug Timeline

Once I build and flashed bugfix-2.1.x

Expected behavior

Pause/stop and park the hotend without reseting.

Actual behavior

Hottend stays in place and the printer resets.

The following output is visible on Proterface when clicking Pause:

RECV: TFT Serial Command: A9
RECV: TFT Serial Debug: SD print pause started... J05
RECV: TFT Serial Debug: SD print pause started... J05
RECV: TFT Serial Debug: SD print pause started... J05
RECV: TFT Serial Debug: SD print pause started... J05
RECV: TFT Serial Debug: SD print pause started... J05
...
...

and then Proterface crashes as well, probably because of this message repeating infinitely.

Steps to Reproduce

  1. Start printing from SD card
  2. Click Pause or Stop button on touchscreen

On 2.1.2.1 the STOP works fine - it parks and stops. PAUSE partially works - it parks, but after pressing CONTINUE it just unretracts and does nothing with a processing message on screen. It does not crash though. Was not able to test 2.1.2.2 because Marlin fails to start with an EEPROM error.
