MKS Gen main board controller can compatible with Ramps1.4, Mega2560 and support A4988, DRV8825, TMC2208, TMC2100 drivers. Features: Integrate 2560 and Ramps1.4 to one PCB, easier wiring and more stable. Use fine quality 4-layer PCB. Use Marlin firmware, same configuration way as Ramps1.4, it can replace Ramps1.4 directly. Support a variety of stepper drivers: 4988, 8825, TMC2208 and TMC2100. Available to work with LCD2004, LCD12864, MKS TFT24/28/32/35/70. Available to connect external large stepper drivers to driver 57 and 86 motor. Use fine quality MOSFET, better cooling, longer and more stable work. Use dedicated power chip, support -24V power input, and solve the heat problem of voltage converter. Stable filter circuit greatly reducesinterference, the problems that the printer crashes or randomly hits. Accept 24V input, reduce the heated bed current to 1/4 that solves the Mosfet heat problem efficiently. The driver terminals color of the main board corresponds to the color of MKS series stepper drivers, which helps to plug the stepper drivers in a proper direction. Retain Servos, AUX-1 and AUX-2 interface of Ramps1.4, provide three 5V output and three output terminals.
