 ## NC-Code Usage
 
 The nc program uses the Q parameters also used by cycle 225:
 
   - **QS500**: Text to engrave
   - **Q203**: Z-coordinate of surface
-  - **201**: milling depth
+  - **Q201**: milling depth
   - **Q200**: safe distance for rapid feed between characters
   - **Q206**: plunging feed rate
   - **Q207**: milling feed rate
