Hi guys, to start, i'm trying to translate the topic because i'm a french student with a bad english level.
I have a problem on my Anycubic mega S " the one which have a blue and yellow screen" , I have bought it there is 3 month ago, but i can't upgrade the firmware, when i try to do it on Cura, the loading is stopped at 50% with an error message.
Then , the printer is disconnected, and i need to unplug and plug again the USB cable to reconnect the printer.
I tried with the last official firmware, and with the marlin firmware on thingiverse.
PS :When i connect my printer to my computer , the anycubic ringtone "tone" 3 time before the connection is ok.
Can someone tell me where is the problem and how i can solve it ?
Thanks, and sorry for the bad english.
