This is the easiest method if you don't want to change any settings.
Newer Marlin versions offer better movement algorithms (like Junction Deviation or updated S-Curve acceleration), which can result in smoother prints.
The compiled firmware has wrong LCD controller definition (usually CR10_STOCKDISPLAY vs REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER ). Fix: In Configuration.h , verify #define LCD_LANGUAGE en and #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER for the stock Sapphire Pro screen. two trees sapphire pro firmware upd
It is worth noting that Two Trees (and their parent company, BIQU) have released newer mainboards (like the BIQU SKR series) that run circles around the stock Sapphire Pro board.
