May 3, 2024 · Finding the optimal extruder spring tension and idler wheel tightness can promote a more consistent filament feed rate, which in turn reduces the risk of clicking, because the filament will keep up with the stepper motor. So, if you hear something knocking at your engine, take a deep breath and pull over safely. Worn or broken gears, the wrong voltage, or a faulty control circuit can all contribute to stepper motor issues. After looking/feeling around I located it coming from the right-side y-axis stepper-motor. Stepper motor failure is a rarer occurrence but can create clicking noises. 4 would be more of an electronic or sensor issue. This can be due to many different reasons such as your nozzle is too close to the print bed, your stepper motor is losing steps, your extruder gears aren’t gripping the filament tightly enough, or you have issues with your bearings which hold pressure on the filament. The whole project is to measure the weight of an object from a robot arm using torque equilibrium, and output its mass on an lcd, something like a manual scale to measure your weight. The 12V for power is good. It’s controlled by an external turbo actuator stepper motor rather than a traditional dump valve and pneumatic wastegate. Therefore, it’s preferable to use sinusoidal wave currents.
