[QUESTION] Elegoo Saturn Remote printing

[git4unrealnondev]

I cannot seem to configure my elegoo saturn with remote printing using UVTools.
I ran an nmap scan and udp ports 53 & 3000 were open and viewable.
Im none too sure how to configure it any.
Im going to try and reverse engineer chitubox calls to my elegoo.
Will report the good word back.

UVtools sends HTTP requests, those are TCP.
Without clear information on comunication i can't make a profile for it.

You can use Wireshark to have the comunication

I did some searching and found that my elegoo uses port 3000 over udp.
It looks like mostly standard gcode and output that you would get out of pronterface.
To connect to printer:
nc -u PRINTER_IP 3000

Heres some of the work that I've reverse engineered.:

M4002 - Get version info
M20 - List files
M27 - Status
M4000 - Where is printer currently.
M6032 'FILE' - Load file
M6030 'FILE' - print file
M3000 - Reads file from memory to netcat?
M33 - Disconnect? / Stop Printing??

Still need to figure out how to upload files to the printer remotely.

Heres an example session from my setup:
linux@archlinux ~]$ nc -u 192.168.1.33 3000
M4002
ok V4.4.3-Z1_LCDZ
M20

To send a file you probably need send a request over UDP and the file bytes.
Using wireshark you can see what chitubox sends when you click on send button

[git4unrealnondev]

Yeah it looks like it sends the M28 command with the filename.
M28 DJIFRAME1.ctb
Looks like it sends the file over in binary.
M29 closes it
I cant seem to get netcat to send files over.
Im using resinator3d to test everything.
