Understanding the Purpose of G-code Preview

What is the main purpose of using a G-code preview before starting a 3D print?

ATo visualize the toolpath and check for errors before printing
BTo clean the printer's nozzle before printing
CTo convert 3D models into G-code automatically
DTo directly control the printer's temperature settings

Identifying Errors from G-code Preview

During G-code preview, you notice that the print head moves outside the build plate area. What does this indicate?

AThe printer's nozzle temperature is set too high
BThe print speed is set too low
CThe filament type is incompatible with the printer
DThe G-code contains commands that exceed the printer's build volume

💡 Hint

Consider what moving outside the build plate physically means.

Difference Between G-code Preview and Real-time Simulation

How does a G-code preview differ from a real-time simulation during 3D printing?

APreview adjusts filament flow; simulation changes print bed temperature
BPreview controls printer settings; simulation edits the 3D model
CPreview shows planned movements before printing; simulation mimics actual printing process including timing
DPreview is only for CNC machines; simulation is only for 3D printers

Impact of Skipping G-code Simulation

What is a likely consequence of skipping G-code simulation before starting a complex 3D print?

AFaster print times because simulation slows down the printer
BIncreased risk of print failure due to unnoticed errors in toolpath or settings
CAutomatic correction of errors by the printer firmware
DImproved print quality because simulation adds extra calibration
