@XH Make sure your M911 command uses straight quotes like this " not curly quotes like “ (it looks like yours are not straight). You can check the M911 command by sending M911 in the console. eg:
M911 Auto save voltage 10.0V, resume 11.0V, script "M913 X0 Y0 G91 M83 G1 Z3 E-5 F1000"You can also check there are no errors in your config.g by getting running it again, with:
M98 P"config.g"Ian
