MKS GEN L V1.0 Motherboard High-Frequency 3D Printer Control Board + Expansion Hot Bed A4988 DRV8825 TMC2100

Use a specific power chip to 12V-24V power input to solve the problem of chip heating and insufficient power. The external backup controller can be used to the external high current controller to drive stepper motors 57 and 86. It can be used for 24 V input, the heating bed current can be reduced to 1/4, and the power is the same, which can effectively solve the heating problem of the heating bed Run Marlin firmware, the configuration is completely equal to Ramps 1.4, it can directly replace Ramps 1.4.Support Ramps 1.4, 2004LCD, 12864LCD, TFT28 and TFT32. X-axis, Y-axis and Z-axis use different color terminals to control the stepping motor and the end, which is for cables.
