Using this belt is easy. First, make sure your 3D printer is turned off. Then, carefully install the belt to connect the stepper motor and the sliding block. When using the printer, avoid over - stressing the belt to prevent it from wearing out quickly. For maintenance, regularly check the belt for any signs of wear or damage. If you notice fraying or stretching, it's time to replace the belt. Also, keep the belt clean to ensure smooth operation.
