There was this 3D printer donated to my school a couple years ago that I am trying to make work. I know it is coded fully since the LCD screen has options that will move the 3D printer bed and nozzle. Except I cant access any of this on my computer. Any advice for getting the printer to work on my computer will be helpful. On windows 10 currently but I can use a windows 7 laptop. I installed a SD card to the 3D printer since it had a SD card slot, I can edit that on my laptop. Any suggestions will be much obliged. Thanks.
What make printer? Do you know google? what makes you think an Arduino forum can help? Have you tried GRBL?
Haven't found anything on google. Fully custom printer. Has one url on the LCD screen but the website is for sale.
Can you post clear, upclose pictures of the control board(s) and other parts?
Use the Attachment and Other options button, crop/resize the photos with MS Picture Manager or similar if needed.
And pictures of the entire printer.
Someone might recognize it from that.
Just focusing on your title "Extracting code/3D Printer" - it would be completely impractical to try to extract the code and make sense of it.
If you can't identify the printer and the program that is on it then it may be possible to upload a different 3D printer program. I reckon you would be much more likely to get useful advice on the RepRap Forum.
if you can connect the printer to your PC with a USB cable and if you use the Arduino Serial Monitor or a terminal program such as PuTTY it may display some useful information about itself when the printer program starts. You may need to experiment to find the right baud rate. I suggest starting with 115200.

Have you tried loading a G-file on the SD card and inserting it?
What is the URL?
What names or logos, if any, are on the main circuit board or boards.
It is unlikely that even a "fully custom" printer has fully custom firmware. Most use open-source firmware like Marlin.
3dprintertek.com is the url, I'll take pictures of the printer soon for reference.
That seems to have been the vendor, not the manufacturer.
