M3D Release SD Card
The latest SD card files released by M3D can be found on the M3D Github ProMega Repository. Follow the steps below in order to download the latest version for your printer. Always be careful when downloading the latest version of the SD card files. New SD card files can cause unintended results such as flipped motor directions or wrongly configured heaters. Always test all motors and heaters carefully before printing after downloading a new update.

Moving the Files onto the SD Card
Back-up your SD card files before updating so you can always revert to your original settings. Now that you have access to the files, locate the SD Card Structure folder in the folder you just extracted. This folder will have two folders Compound and K'Tana, select the folder based on what nozzle you currently have mounted on your printer. In both of these folders are the files you want to copy to your microSD card. This should be four folders: sys, gcodes, macros and www. Plug in the microSD card into your computer with the microSD card reader and copy the files onto it. Your SD card should look like this. Using WinDiff or a similar program to distinguish differences between the latest SD card release and your files might be a good idea.

Testing and Tuning
Once you have updated the SD Card files on the microSD card. Test all your motors and heaters one by one to ensure the new settings are compatible with your wiring and board. If you changed any settings in your previous configuration, you will have to add these settings and commands in your new updated version. If any of the motors or heaters are flipped, this guide will help.
