M109 reboot printer. #787

Closed Francis663 closed 4 years ago

Francis663 commented 4 years ago

MK4duo V4.4.0 downloaded 5 Fev 2020. Configurator not used. The printer reboot when enter the G-Code M109 S210 just after M104 S210. M104 S210 is to set the hotend printer temperature. M109 S210 is to wait until the temperature reaches the target (210°C)

Note: the printer does not reboot when the hotend is already >= the target temperature.

Config: Cartesian, One hotend, Board Megatronics V3.3.

I investigate inside the source code and found:

The problem occurs when the system want to write a status line in the Nextion display.
In the nextionlcd.cpp, inside the function LcdUI::status_printf_P (line 1430), it's a function used: vsnprintf(status_message, NEXTION_MAX_MESSAGE_LENGTH, message, args); This function hang the printer.. When I comment this function (//) it's working without reboot, but the message is not correct, for sure.
