+## 1 · What’s in this repo
+* `Configuration.h` & `Configuration_adv.h` already tuned for Micromake D1 geometry.  
+* English 20×4 LCD presets.  
+* Safe temperature limits (270 °C hot‑end / 120 °C bed).  
+* Smart auto‑fan on MOSFET D.  
+* Updated motion limits for faster homing (100 mm/s).  
+* EEPROM, SD‑card, auto‑delta‑calibration G33 ready.
