Using these timing pulleys is easy. First, make sure your stepper motor is turned off. Then, align the pulley's inner diameter with the motor shaft and use the M3 fastening screws to secure it in place. For 3D printers, you'll need to carefully position the pulley according to your printer's design. When handling the pulleys, avoid dropping them as this could cause damage. Also, keep them away from moisture and extreme temperatures. To maintain these pulleys, clean them regularly with a dry cloth. If you notice any signs of wear or damage, replace the pulley promptly to ensure the smooth operation of your 3D printer or other mechanical projects.
