What you need
- Stepper motor
- GT2 Belt
- Pulley cord
Steps
- Check the datasheet for compatibility of your GT2 belt with this pulley.
- Install the stepper motor at the base of the support or on the moving component, ensuring that the shaft is well centered and stable.
- Pass the GT2 belt through the GT2 housing and around the stepper motor pulley.
- Insert the GT2 belt into the GT2-20T-6.35 6mm pulley, ensuring it is taut but not too tight to avoid excessive friction.
- Check the tension of the GT2 belt and adjust if necessary.
- Connect the stepper motor to the control system (e.g., Arduino) following the motor manual instructions.
