MKS Gen L 2.1 motherboard for 3D printer parts control board

MKS Gen L 2.1 motherboard for 3D printer parts control board, MKS-GEN L V2.1 Integrated Controller Compatible with Ramps 1.4/Mega2560 R3

Features MKS Gen L 2.1 motherboard:

• Integrate 2560 and Ramps1.4 to one PCB, easier wiring and more stable.
• Use high-quality 4-layer PCB.
• Use Marlin firmware,same configuration way as Ramps1.4, it can replace Ramps 1.4 directly.
• Use special power chip, support 12V-24V.
• Support a variety of stepper drivers: 4988,8825, TMC2208 and TMC2100.
• Available to work with LCD2004, LCD 12864, MKS TFT24/28/32/35/70.
• Accept 24V input, reduce the heated bed current to 1/4 that solves the Mosfet heat problem efficiently
• Available to connect external large stepper drivers.
• 9Retain Servos, AUX-1 and AUX-2 interface of Ramps 1.4, provide three 5V output and three 12V output interfaces.

MKS-GEN L V2.1 Integrated Controller Compatible with Ramps 1.4/Mega2560 R3 features:

1. Mega2560 and Ramps 1.4 are integrated in the board, which avoids the complicated connectors.
2. Supports a variety of step-by-step drivers such as A4988, DRV8825, TMC2100 and LV8729, available to change stepper motors and motors that users like.
3. Reserve the signal from the external controller, available to connect an external high current driver to drive stepper motors 57 and 86.
4. Use high quality MOSFET, better cooling and more stable.
5. Use a specific power chip, support 12V-24V power input and solve the problems of chip heating and lack of power.
6. The stable and reliable filter circuit greatly reduces the interference and avoids blockages as possible in the printing process.
7. Use the CH340 serial port chip, install the unit more easily than 16U2.
8. Run the Marlin firmware, the configuration is completely identical to that of Ramps 1.4, and is available to directly replace the Ramps 1.4.
9. Support Ramps 1.4, 2004LCD, 12864LCD, TFT28 and TFT32.
10.  Available for the 24V input, the hot bed current can be reduced to 1/4 with the same power of the system, which effectively solves the problem that the MOSFET of the heated bed is heated.
11. The X axis, Y axis and Z axis with different color terminal control stepper motors and limit switches, which is convenient for wiring.
12. Connect the step-by-step controllers according to the different color terminals, which decreases the probability of recoil and avoids the damage of the controller board.

Can I use the MKS Gen LV 2.1 board instead of V 1.0?

V2.1 Differences

• For foam cutting, the only difference is the orientation of the U-axis.
• On the V2.1 board, pin D42 is not exposed, which is used for the U-Min switch.
• We believe it is used for the TMC2208 UART Z-controller which appears to be a solder pad.
• If you don’t intend to use the homing function, the board will work fine with the original firmware.

Packages Include:

• 1pcs of MKS gen L 2.1
