3D Printing - G-code Fundamentals
If a G-code simulation shows the print head moving below the print bed level, what is the most likely cause?
If a G-code simulation shows the print head moving below the print bed level, what is the most likely cause?
medium📝 Analysis Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Analyze Z-axis movement below bed
Movement below bed level usually means the Z=0 reference is set incorrectly in the G-code or printer settings.Step 2: Exclude unrelated causes
Heating, filament jam, or speed do not cause nozzle to move below bed in simulation.Final Answer:
Incorrect Z-axis zero position in the G-code -> Option AQuick Check:
Z below bed = wrong zero position [OK]
Quick Trick: Z below bed means zero position error [OK]
Common Mistakes:
- Blaming heating or filament jam
- Ignoring coordinate system errors
