Make your 3D printer quieter and upgrade WiFi! Today there is another tutorial with smaller improvements to our large 3D printer optimization tutorial. Probably not everyone has the desire and time to rebuild the complete 3D printer and would like to change perhaps only small things. Since we have just needed a brand new Anycubic i3 Mega S 3D printer, we show again a few 3D printer optimizations that are relatively quick to do and also help the 3D printer to a better 3D printing, make the 3D printer quieter, update the firmware, save energy and how to retrofit 3D printer WLAN!
