Because the T3 is essentially an Ender 3 clone using a modified , many users switch to custom Marlin builds for significantly better control.

Updating to optimized firmware yields the following specific improvements: If you share with third parties, their policies apply

: The T3’s "Fast Mode" and "Jam Detection" are known to be buggy in earlier versions (like v3.0). Updates often let you disable these or improve their logic so they don't ruin prints unnecessarily.

Best-in-class input shaping; print speeds well over 150mm/s with pristine quality; edit configuration files instantly via a web browser (Mainsail/Fluidd).

: Some builds allow heating up to 285°C (requires an all-metal hotend upgrade).

If you want the absolute "better" experience, moving to Klipper (via a Raspberry Pi or Sonic Pad) is the gold standard. Klipper offloads the processing power from the printer's 32-bit board to a more powerful processor, allowing for even higher speeds and much easier configuration changes.
