3D Printing - G-code Fundamentals

A G-code file contains the line G1 X50 Y25.3 E22.4 but the printer ignores the extrusion (E) value. What is the likely cause?

AThe printer firmware does not support extrusion commands

BThe E value is missing a unit like mm

CThe G1 command cannot include extrusion

DThe printer is out of filament

Step-by-Step Solution

Solution:

Step 1: Understand the role of the E parameter
E controls how much filament is pushed out (extruded) during movement.
Step 2: Analyze why extrusion might be ignored
If extrusion is ignored, a common reason is the printer has no filament loaded or it is jammed.
Final Answer:
The printer is out of filament -> Option D
Quick Check:
Extrusion ignored usually means no filament = A [OK]

Quick Trick: No extrusion? Check filament supply first [OK]
