Overview:In response to problems with open source control boards such as Ramps 1.4, the developers of Makerbase have optimized and developed a new product, mks-gen L, to provide users with more flexible options. Feature:1. 2560 and 1.4 ramps are integrated into the board, avoiding complicated connectors.2. Support A4988, DRV8825, TMC2100, LV8729 and other stepper drivers, and the drivers and stepper motors can be replaced according to user needs.3. Reserve an external driver signal that can be connected to the high-current driver to drive 57, 86 stepper motors.4. Using high-quality MOSFET, heat dissipation is better and more stable.5. Use special power chip, support 12V-24V power input, solve the problem of chip heating and power shortage.6. The stable and reliable filter circuit greatly reduces interference and avoids failures during the printing process as much as possible.7. By using the CH340 serial port chip, it is easier to install the driver than the 16U2.8. Run Marlin software, the configuration is exactly the same as 1.4 ramps, which can directly replace 1.4.9 ramps. Support Ramps 1.4, 2004LCD, 12864LCD, TFT28 and TFT32.10. 24V can be input, under the same power of the system, the hot bed current can be reduced to 1/4, effectively solving the problem of hot bed MOSFET heating.11. X-axis, Y-axis and Z-axis use different colored terminals to control the stepper motor and stopper, which is convenient for wiring.12. Connect the stepper driver according to the terminals of different colors to reduce the possibility of inversion and prevent damage to the controller board.
