  • Why is the alignment of the axes important in a 3D printer
    It ensures precise movement and accurate layer positioning for high-quality prints
  • What could happen if the controller board fails to correctly synchronize the motors and the nozzle temperature?
    It can cause print defects like layer shifts, poor extrusion, or even hardware damage due to overheating or misalignment
  • What component holds the filament before it is fed into the printer?
    spool
  • What is the main function of the print head in a 3D printer?
    To feed, melt, and deposit filament through the nozzle onto the print bed
  • Which component detects when a moving part reaches its endpoint?
    limit switch
  • How do the limit switches and motors work together during printer calibration or homing?
    Motors move the axes until they trigger limit switches, setting a reference “home” position
  • What mechanical parts drive the motion of the print head and bed?
    Motors
  • Which part melts and extrudes the filament onto the print bed?
    nozzle
  • How does the motherboard or controller affect printer performance?
    It controls and coordinates all components such as motors, sensors, and heating elements
  • Explain how filament feeding involves multiple components of the printer
    The filament unwinds from the spool, passes through the extruder in the print head, is melted by the nozzle, and deposited on the print bed
  • What is the flat surface where the 3D print is built?
    heat bed
  • Which part of the printer moves to position the nozzle along the X, Y, and Z directions?
    Axes
