Getting Started:

Cohesion3D ReMix comes with the Smoothie Firmware already flashed and a preconfigured MicroSD card installed in its respective socket. 

Installing Smoothie Drivers:

If you run Windows lower than Windows 10, you may need to install the Smoothie Drivers.  Mac and Linux Operating Systems do not need any drivers.

Please see this page for the driver install and further information:

Windows 10: Do NOT install any drivers. 

Windows 8, 7 or earlier: yes, install the drivers using the smoothieware-usb-driver-v1.1.exe at the top of the page.  

Windows 8.1: see the note on that site if you have any issues getting the board to be recognized by your computer. 

First boot:

Plug the board (with nothing else plugged connected to the board at this time) into the computer with a USB cord. On the board, the 2 middle green LEDs should perform a "slow blink" while the PC installs the device.  After a short while, those LEDs should now be flashing quickly. This signifies that the PC and ReMix have figured everything out, and the device should have been fully installed at this point and you should see a mass storage device like a flash drive in My Computer.  The config.txt file should be on it.  You should be able to double click on it and open it in a text editor.  We recommend Sublime Text as the editor of choice for manipulating the config file.  At any point, you can save the file, use the "safe eject" command in Windows Explorer to dismount the smoothie drive, and then either disconnect the board from USB or press the Reset button, which will load the new settings.


Cohesion3D ReMix is configured by editing config.txt - this is a plain text file located on the MicroSD Card in the board.  The config file is made up of a series of modules. A module first needs to be enabled.  In this example,

#extruder.hotend2.enable                          true

the module is initialized in this line, and set to true, but the # is a comment designator which must also be removed from this line and any other lines of the module in order to make it work. 

Note:  Motor 6 and MOSFET 6 share control signals with the 4 status LEDs on the board.  In order to take advantage of these, the following line needs to be uncommented in or added to the config file:  leds_disable true


  • Ethernet: The "Ethernet Expansion" header receives a LAN8720 module.  This can be found on eBay and Amazon . There is a line at the bottom of the config file to enable network.  Careful, as enabling that line without the LAN8720 connected will cause the ReMix not to boot. 
  • Wifi: The ESP8266 on ReMix can act as a serial bridge, meaning you can send gCode commands to its IP address from a software such as Pronterface, which supports sending to an IP address. In order to do this, 2 physical shunt jumpers need to be installed.  Please see the "WiFi Enable" section of the pinout diagram.  The firmware running on the ESP8266 is called ESP-Link.
