MKS-Gen L

Overview
:
Aiming at the problems exist on the open sourced controller board such as Ramps 1.4, the developers in Makerbase specially optimize and develop a new product, MKS-Gen L, which provides more flexible choices for users.


Features:
1. 2560 and Ramps 1.4 are integrated in the board, which avoids the complicated connectors.

2. Support a variety of stepper drivers such as A4988, DRV8825, TMC2100 and LV8729, available to change the stepper drivers and motors as users like.
3. Reserve external driver signal, available to connect external high-current driver to drive the 57 and 86 stepper motors.
4. Use high-quality MOSFET, better cooling and more stable.
5. Use specific power chip, support 12V-24V power input, and resolve the problems of chip heating and power shortage.
6. Stable and reliable filter circuit greatly reduces interference and avoids crashes as possible in the process of printing.
7. Use CH340 serial port chip, more easily install the drive than 16U2.
8. Run Marlin firmware, the configuration is completely same as Ramps 1.4, and available to directly replace the Ramps 1.4.
9. Support Ramps 1.4, 2004LCD,12864LCD, TFT28 and TFT32.
10. Available to input 24V, the heated bed current can be reduced to 1/4 at the same system power which effectively resolves the problem that the MOSFET of heated bed heats.
11. X axis, Y axis and Z axis with different color terminal controls the stepper motors and endstops, which is convenient to wire.
12. Plug the stepper drivers according to the different color terminals which decreases the  probability of reverse and prevents the controller board damage.

A4988

A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.

In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.

A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.

Package Included:

1x MKS-Gen L V1.0 board
1x 50cm USB cable
5x A4988 Stepper Motor Driver
5x Heatsink
