I am currently using a HOFI x1 3D printer and I would like to change the start bed temperature to 102°. As far as I understood, it is necessary to add the M140 S102 command. But I don't see where to add this command. Could someone provide me the path to the file? and is there any other thing to do for the software to recognize the change. I have no skills in encoding, so thank you in advance for you help.
