What will be the result of executing the following G-code commands?
G0 X10 Y10
M106 S255
G1 X50 Y50 E10
AThe print head moves slowly to (10,10), fan turns off, then moves to (50,50) without extrusion
BThe print head homes, fan speed is set to 0, then moves to (50,50) extruding filament
CThe print head moves quickly to (10,10), fan turns on full speed, then moves to (50,50) extruding filament
DThe print head moves quickly to (50,50), fan turns on half speed, then extrudes filament at (10,10)
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the G0 command

    G0 X10 Y10 moves the print head quickly to coordinates (10,10) without extrusion.
  2. Step 2: Analyze the M106 command

    M106 S255 sets the fan speed to maximum (255 is full speed).
  3. Step 3: Analyze the G1 command

    G1 X50 Y50 E10 moves the print head to (50,50) while extruding 10 units of filament.
  4. Final Answer:

    Print head moves fast to (10,10), fan full speed on, then moves to (50,50) extruding filament -> Option C
  5. Quick Check:

    G0 = fast move, M106 S255 = fan full, G1 with E = move + extrude [OK]
Quick Trick: G0 = fast move no extrusion; G1 with E extrudes [OK]
Common Mistakes:
  • Assuming G0 extrudes filament
  • Thinking M106 S255 turns fan off
  • Confusing coordinates in commands
