Belt-driven systems use a toothed belt and pulley for linear motion, offering high speed but lower precision. Leadscrew systems use a threaded rod for precise linear motion with higher accuracy but typically slower speeds.
Microstepping divides each full step into smaller increments, improving resolution and smoothness. Higher microstepping (like 1/16) provides smoother motion and better precision but may reduce torque at high speeds.
Optimal layer height should align with your Z-axis resolution. Choose layer heights that are multiples of your steps-per-mm resolution to avoid micro-stepping errors and ensure consistent layer adhesion.
Required torque depends on load inertia, friction, and acceleration requirements. Consider the mass being moved, belt tension, leadscrew efficiency, and desired acceleration when sizing your stepper motor.
Higher gear ratios increase torque and precision but reduce speed. Choose based on your application needs: use 1:1 for high-speed applications, higher ratios (2:1 to 5:1) for heavy loads or high precision requirements.
Use the M92 G-code command to set steps per millimeter. For example, M92 X80.00 sets the X-axis to 80 steps/mm. Update your firmware configuration file with these values for permanent changes.
Maximum speed is limited by motor torque curve, power supply voltage, driver current settings, and mechanical load. Higher voltage and current increase speed capability, but heat management becomes critical.
Theoretical calculations provide a starting point, but real-world factors like belt stretch, backlash, thermal expansion, and manufacturing tolerances may require fine-tuning through test prints or measurements.
