Hey bob_the_vampire,
Is it possible that something else is using your serial port? Also, does the mariner user have access to the serial port?
Can you try installing something like minicom and connect to /dev/serial0 with baud rate 115200?
Once you do that, if you send a command such as M4000, does the printer reply successfully? What if you send the command M4006?

Hi thanks for the quick reply, I'm still on a learning curve with those raspi.
So i managed to install minicom and configure it, next I tried to communicate with the mars
both m4000 and m4006 nothing come back, next I tried to loop back the serial to be sure nothing was keeping me from using it and everything I sent came back instantly so the problem isn't coming from the pi nor your soft
I'll take a third look to my cables and the welds on the Mars MB
Edit: I just realize that I don't have the 3.3V at TX RX on the mars MB is it normal?

ok! so after repairing the RX pad on the elegoo MB I got it too work!
So now it only need to wait for the .cbddlp files to be supported
Thanks a lot for all this dadwarf and l9o
P.S.: does someone already verified if it could be done to use a pro firmware on a standard mars?
which are the difference between them anyway?

I inadvertently loaded the mars pro_3.5_UI_20200824.bin and other Pro files--from that latest package offered by Elegoo--onto my plain ol' Mars (s/n M20Silver20200401) and it runs just fine. Didn't realize I had done it 'til a couple days later when i went to clear the USB drive and load some .ctb files to it...
Don't see that it does (or doesn't) do anything the Mars firmware didn't...

No that's fine I realized that my firmware version (4.3.2) already support ctb files, I don't know from which version it is added but it's strange that we need to force chitubox to use this format or make it think we have a mars pro so it offer ctb as default.
Out of this everything is working perfectly, so you could tell it is compatible with the non-pro ones.
I added Samba winbind on mine for easier USB file management it feel easier for me than winscp
P.s. A friend of mine got the V4.2.20.3 with the network ready board and told me that ctb files work on his too
