# KS0092 keyestudio 3D Printer Kit MKS Base V1.2 + 5x 8825 + LCD 2004 Smart Controller Download Resource: [Resource](./Resource.7z) ![](media/image-20251230145634600.png) ## 1. Description 1.The new MKS Base 1.2 3D Printer Controller board combines and improves the assets of the RAMPS 1.4 and Arduino Mega 2560 boards on a fantastic single board solution. The MKS Base 1.2 is an optimal 3D printer controller solution for your Reprap 3D Printer. 2.LCD 2004 Smart Controller It contains a SD-Card reader, a rotary encoder and a 20 Character x 4 Line LCD display. You can easy connect it to your Ramps board using the "smart adapter" included. After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. 3.The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling). ## 2. Package list - 1pcs MKS base V1.2 - 1pcs Lcd2004 smart Controller - 5pcs 8825 stepper driver - 1pcs USB 2.0 cable ## 3. Connection Method A. Mount DRV8825 correctly, don’t mount reversely, or they will be burnt, as shown below: ![](media/image-20251230145807440.png) B.

Application of Slicer Software A. Run Repiter-Host,click Load to open a printing model. ![](media/image-20251230152836955.png) B. Click Printer Settings to complete some setup, referring to below figure. ![](media/image-20251230152902637.png) C. Enter Object Placement to set placing position, printing size and so on. ![](media/image-20251230152924255.png) D. Click Slicer to set slicer, like printing speed. After setting slicer, click Start Slicing to begin slicing. ![](media/image-20251230152945363.png) ![](media/image-20251230152951439.png) E. After slicing, go to Preview→G-Code Editor, copy G-Code to SD card, and then insert the card into the main board. It is time to kick off the print! Though the LCD screen go to : Print from SD→Desired File. Or you can connect your 3D printer to computer using a USB cable to start the print. ![](media/image-20251230153013497.png) F. Click “Connect”and then click “Start Print” to begin the print. After some time, your printer gets ready and the buzzer rings, then you should press the button on LCD to start. ![](media/image-20251230153546554.png) G. We just introduce a simple method about printing. Thanks to selling only main board by us, you should design your own structure and outlook of your 3D printer, and you should also set your own configuration to meet your need. After you assembling your printer, the printer need to be leveled, so you can make some setup in Preview and Manual Control, and surf the internet for further information. ![](media/image-20251230153606512.png) H. We have a G-Code to test the main board. Power it on, open limit switch and stepper motor, drive three motors; put a Fnbduino.gco file to Preview, click Start Print, if the motors rotate, X/Y/Z value in Manual Control changes, the main board works as shown below: ![](media/image-20251230153715449.png)
