Installation


Installation instructions can be found in the gMax 2 PRO User guide available in the download section of the forum. We recommend updating both the Skr firmware and the Touchscreen firmware to avoid compatibility issues. The user guide can be found under the gMax 2 PRO Manuals folder in the SD Card files link:

Note
Do not use the configuration files for the gMax found on the github page. Always download the gMax firmware found on our forum to ensure it works on your printer. Modifying the firmware is for advanced users and it not recommended. Making changes to the firmware could cause damage to your printer not covered under warranty.


A huge thank you to the entire Marlin Development team. Our source code is available in the .zip file.
