This is just a small and simple stage.

It is easy to make.

Mechanism

The mechanism is also simple, converts rotational motion of a motor to linear motion useing a screw.

EXPANDED TECHNICAL DETAILS

Precision Motion Control

This project builds a miniature linear actuator for CNC, laser engraving, or precision medical experiments.

  • Lead Screw Drive: Uses a standard threaded rod (M5 or M6) or a specialized T8 lead screw. A stepper motor rotates the rod, moving a carriage along a set of smooth linear rods.
  • Stepper Driver Control: Driven by an A4988 or DRV8825 module. The Arduino sends STEP and DIR pulses, allowing for sub-millimeter positioning accuracy.

Software Calibration

  • Homing Sequence: Includes a Limit Switch (Endstop) at the "Zero" position. Upon startup, the stage moves until it hits the switch, calibrating the internal coordinate system.
  • Speed Ramping: Implements an "AccellStepper" library logic to smoothly accelerate and decelerate the carriage, preventing missed steps and ensuring mechanical longevity.
