Non-marlin to marlin upgrade, help needed

Hello good people.

Yep, i got cheap 3d printer, it works(ish).
Decided to flash it to marlin as mine came with hell knows what.
Problem is i dont know some of bits that are on this printer to get config going. Dont want to break/brick it.
Namely hot end and bed heater/sensor specs.

Is there any way to check current settings under the hood so i could carry them over to marlin ?

The board is GT2560 Rev A. very few menu options, nothing for tuning/setup. Basic to say the least.

This is the printer. CTC branded.

Any ideas how to proceed ?

If it is a Prusa clone... Almost for sure it is running Marlin already. You should ask for the source code so you can make changes. With the source code, you can cross its existing Configuration.h files over to the new code base.

GT2560 is a very common board from china... [www.geeetech.com]

Well, i know the board, problem is the bits connected to it. Temp sensors and heaters.

My point is... If this is a Prusa clone, and it is running the Prusa firmware... That is Marlin. It will be a modified version of Marlin. But it is Marlin.

If what I'm saying is true, you should be able to grab the Configuration.h file from their repository. But here might be another way to get that information:

In the LCD Menus... If they have enabled the LCD_INFO_MENU in the firmware build... You can go look at the board and thermistor information:
```
#if ENABLED(LCD_INFO_MENU)
#if ENABLED(PRINTCOUNTER)
void lcd_info_stats_menu();
#endif
void lcd_info_thermistors_menu();
void lcd_info_board_menu();
void lcd_info_menu();
#endif // LCD_INFO_MENU
```
