+ | - Connect programmer to computer | ||
+ | - Connect programmer to motherboard | ||
+ | - Open Arduino IDE | ||
+ | - Select the programmer you use in the Tools -> Programmer menu | ||
+ | - Choose "Burn Bootloader" | ||
+ | - Go back to normal life, flashing via USB cable direct to your 3D printer. | ||

+ | All your pins on the MKS Gen L should be connected to the ICSP port (see first image below). | ||
+ | |||
+ | - Connect pin 10 on the uno to the RST on the MKS Gen L ICSP port (see image #2 for pinout) | ||
+ | - Connect MISO, MOSI, SCK, VCC, GND to the matching pins on both MKS ICSP and uno ICSP headers. | ||
+ | - Flash the bootloader sketch. | ||
+ | - Open the arduino serial monitor. | ||
+ | - You may need to choose the correct baud rate to see text correctly. | ||
+ | - Follow the prompts in the serial monitor. | ||
