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


The integrated mainboard driver MKS-GEN L V1.0 for 3D printer has been developed by Makerbase to optimize existing problems on the open source controller board such as Ramps 1.4.
This product offers more flexible options for users.

The MKS Gen L V2.1 is recommended as the main board for the OAT when using NEMA steppers. It greatly simplifies the required wiring, which reduces the likelihood of hardware problems.

NOTE: On the MKS Gen L V2.1, DIAG wiring is handled internally. A jumper is required to set the board logic voltage to 3.3V instead of 5V.

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


- Mega2560 and Ramps 1.4 are integrated in the board, which avoids the complicated connectors.
- 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.
- Reserve the signal from the external controller, available to connect an external high current driver to drive stepper motors 57 and 86.
- Use high quality MOSFET, better cooling and more stable.
- Use a specific power chip, support 12V-24V power input and solve the problems of chip heating and lack of power.
- The stable and reliable filter circuit greatly reduces the interference and avoids blockages as possible in the printing process.
- Use the CH340 serial port chip, install the unit more easily than 16U2.
- 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.
- Support Ramps 1.4, 2004LCD, 12864LCD, TFT28 and TFT32.
- 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.
- The X axis, Y axis and Z axis with different color terminal control stepper motors and limit switches, which is convenient for wiring.
- 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. I 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. Simply install it by following the instructions here. Use the MKS Gen L V1.0 board for CNC foam cutting.

How to use Homing with the V2.1 board

You can use homing with the V2.1 board with a modified firmware listed below. However, there is a small caveat. You will only be able to use 4 switches and soft limits. Having a limit switch at each end of the axis will not work as the D2 pin is now used for the U-Min pin. The D2 pin is normally used for X-Max.

This firmware version has been created that works for the V2.1 board.
