MKS SBASE is made by Makerbase a.k.a MKS (Makerbase), a Chinese manufacturer of 3D Printer controller boards also known as a mainboard that can run Marlin, Repetier, and other firmware.
MKS SBASE V1.3 Overview
This is a 32-bit control board for your 3d printer with an ARM-Cortex M3 LPC1768 microcontroller. It supports 12V-24V DC input.
Here is the pinout configuration from the MKS SBASE github page;
MKS SBASE 1.3 OnBoard Stepper Drivers
Its five motor outputs are powered by OnBoard DRV8825 stepper drivers with six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and up to 1/32-steps. If you are using Marlin Firmware the stepper motor current can be adjusted in the Configuration_adv.h file.

Fan Wiring Connection
The MKS SBASE 1.3 comes with limited connections for your 3d printer’s extruder fans, board cooling fans, and part cooling fans. This connection is for your 3d printer’s cooling fan as it kicks on after your first layer has been completed during the print.
But what about the Extruder Fans?
You might be asking yourself how to connect the extruder fans, at least that is what happened to me. I reached out to King at makerbase and he suggested connecting them to the secondary input voltage connector. But then I thought well that would mean the fans would always be on which is not ideal or power friendly.
So I searched for a better way and I found that you can use a relay or even better a MOSFET Driver Module!
These little guys make it easy to add low amp hardware and control them with the signal pin. Simply wire these to the secondary power input on the board, wire up the fans, and then connect the signal pin to a free digital pin. Then just modify your firmware configuration to activate the pin for the extruder fan power. These support up to 24v which makes them a great and affordable choice.
Smart Controllers (Screens)
MKS SBASE 1.3 supports many Smart Controllers and Touch Screens. They have their own line of touch screens which are pretty nice.
USB and SD Card Compatibility
The MKS SBASE 1.3 board does not come onboard SD or USB KEY connectors. What’s pretty awesome about the MKS TFT Touch Screens is that they come with integrated SD and USB Key connectors!
Most other TFT Screens and Smart controllers come with an SD Card Slot Standard, just be sure whatever you are choosing has that feature should you want to use it.
Summary
The MKS SBASE 1.3 is a great 32-bit mainboard controller board that gives you much-improved performance over 8-bit boards. It’s compatible with Marlin firmware and the open-source community is improving it every day so it will only get better. Its touchscreen LCDs make it an attractive and easy-to-use interface with added USB convenience.
I have NEMA 17 motors and an MKS v3.1 abase Board for my printer build. The cables that cane with my motors are key’d At the motor end have a simple flat 4 pin female plug end with no “key” that matches the MKS board xyz axis plugs. You can turn them either way. What is correct.? I can change the ends to the correct matching plug for the board but don’t know the correct pinout to properly run the motors. Please…any help?? Thanks
Hi Bernard,
You might be over thinking it. Usually reversing the connector will just invert the stepper direction.
Here is the Datasheet if you need see the pinout on page 4.
Have you tested it with power yet?
Thank you for replying. I am building this printer https://repalmakershop.com/pages/core-xy-3d-printer-build-instructions
It is about 75% done. No wiring yet. I’m a rookie and the person who put this up as a project is well experienced but has left out so much I believe because he is taking the information in his head as common knowledge. Not so. I’m having some difficulty getting the parts from him and have had to source my own after waiting weeks. My question was due to research into wiring the printer correctly. I am dreading the set up at power on. I have no clue how to set up or calibrate or update the MKS board with what ever is required. None of this information is provided by the designer. I’m on my own but am glad I found your site. Maybe when I need information next I can ask questions here. Thanks again.
We’ve all been there and we all start somewhere. But you’re doing everything right asking questions.
Install one part step by step and test! Get some firmware like marlin installed on your controller first and get power running.
Then you can test your motion, limit switches and calibration settings.

how do you compile marlin to run on the mks smase board, since you cant upload direcyley to the board ?
Hi Bill,
For Marlin 2.0 the easiest way to edit and flash your mainboard is to use an IDE like VS Code. There is an extension Platform IO that you need to install with VS Code and that should get you going. We are working on a tutorial for this so be sure to check back soon. Thanks!
I’ve dug out my 3d printer after a couple of years in mothballs, did you ever do the tutorial for flashing Marlin 2.0 onto a MKS v1.3?
Nice! I have resurrected a couple of printers too and it’s amazing what a firmware update can do to them.
We have Marlin 2.0 Beginner Guide for 3D Printer Firmware but it’s not specific to MKS Base V1.3. Should have no issues flashing over on it.
