Proven & stood the test of time. However, do not use this if you have beacon/carto, or if your firmware version is 1.7.0 or newer.
if you want to test, in the meantime, ssh into on the printer with the following: (Extended documentation about SSH access here)
ssh mks@[printer's IP]
Password is: makerbase
Next, copy this, paste it and press enter.
cd /home/mks/printer_data/config/ && git clone https://github.com/qidi-community/config-xplus4 && sed -i '/<---------------------- SAVE_CONFIG ---------------------->/i [include config-xplus4/*.cfg]' printer.cfg
then do a firmware restart.
if you already installed, the current update procedure is pasting and running this line:
cd /home/mks/printer_data/config/ && rm -rf ./config-xplus4/ && git clone https://github.com/qidi-community/config-xplus4
then do a firmware restart. Beware that if you had done any modifications to the mods stored in the config-xplus4 folder, they'd be erased by this action.
