Elegoo Mars 3 Pro - LED Fan only when printing

thingiverse

--------------------- BEFORE YOU USE ------------------------ I don't know if this works for the Regular Mars 3 without Pro but my sense for technology tells me that it should work. So if somebody tried and it worked please tell me so i can delete this section. Thanks: ----------------------------- END ------------------------------ As some of you know, the LED fan of the Mars 3 Pro is a little annoying. I asked the Elegoo Support if there is an option that the fan only runs while printing. They send me the .gcode file attached. What you can do with this File: - set M8030 I-1 (sets the filter fan to "always on") - set M8030 I-2 (sets the filter fan to "on while printing") - set M8030 T-1 (sets the LED fan to "always on") - set M8030 T-2 (sets the LED fan to "on while printing") I uploaded the file with the Setup: "LED fan only when printing and filter fan always on". If you want it an other way just insert the right code. After you inserted the right code for you, put the file on an usb stick and "print" the file. The changes will apply immediately if you done everything correct (support says you have to restart). Have fun with it :-)
