Mks sgenl v2.0 problem #28

Closed AlexejLach closed 3 years ago

AlexejLach commented 3 years ago

mks sgen l v2.0 stopped working drivers burned out. if i insert a new driver, they get very hot. lost connection with mks tft 35. Later I connect through the repeaterhost and everything works, but not the motors. As soon as I start moving the printer, the error and the connection is lost. please tell me what could be the problem? with mks gen l v1.0 board everything works!

AlexejLach commented 3 years ago

Of course! But you need set MKS TFT35's baudrate same as MKS Gen_L

MKS TFT35： In mks_config.txt file : 

#baud rate (9600:1; 57600:2; 115200:3; 250000:4)
>cfg_baud_rate:4

MKS Gen_L(Marlin) in configuration file
