MKS SGEN_L V2.0 is powerful 32-bit 3D printer control board. The CPU is LPC1769 120MHZ, SGEN_L V2 hardware Integrated 4KB EEPROM, 5AXIS and dual Z interface, has 2 way FANs and Dc12/24V out interface, support TMC UART and SPI mode...
I purchased two different MKS SGENL V2.0 from you for my printers. I use one of the motherboard without any problem, but the screen does not work on the other motherboard. I tried 3 different screens but none of them worked. I've tried different serial port configurations and settings. I've used the same screens on ramps and they all work. You can understand this by watching the video.When connecting the motherboard to the computer, the computer detects the motherboard. I even connected through the repaiter host and the epprom settings I made were successfully saved to the motherboard. I realized that the firmware writing process was successful, from the change of the firmware filename. I even sent m106 command on the repaiter host and the fans started working. I think there is a problem with EXP1 and EXP2 outputs. https://streamable.com/26x9dyhttps://streamable.com/7f4luu
