Updating SD Card Structure
While your printer was being shipped, it is possible that a new SD card structure was released. More explanation of the SD Card files can be found in the next guide. To ensure that you have the latest files on your SD card, please follow the guide below.
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.
Downloading Directly from the Repository
Downloading Official Release
Downloading Pre-Release
This option is not always recommended, but it will allow you to get the latest configuration files, regardless of official release. Once you have found and opened the M3D Github ProMega Repository. Press the Clone or download button circled below and then click Download ZIP. This will download a .zip file of the repository.
Downloading from Github
This is the recommended option.
Go to the M3D GitHub Promega Repository Releases and download the latest release. Download the .zip folder for the extruder head that you currently have mounted. The Promega can come with either the K'tana (two nozzles) or the compound (1 nozzle).
Downloading the Latest Release
Click ProMega.
Click Public SD Release.
Browse through the releases. Choose one.
A .zip file is a compressed folder. You will have to first extract the file before you can get to it's contents. Find the file you just downloaded and extract it into a folder. Right click the file and then select Extract All. This will move all the files in the compressed file into a folder. You can now access the new SD card files.

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.

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.
