If this is the case, you should try to feed the filament through manually with your hand while the hotend is at extrusion temperature. It’s possible that something could be impeding the extrusion flow of your printer like a cold-end blockage. Not having micro-stepping jumpers installed properly on the RAMPS board.If you follow the first three causes, you’ll most likely have your answer but there are a few other causes to keep in mind:

Motors can have metal shavings inside or a misalignment which will give you issues. There are a few reasons why it could be faulty such as the internal motor coil being damaged but in this case, you’ll want to contact your seller and get a replacement or a refund. Once you do this check whether the motor does the same thing, and if it does it likely means you have a bad motor connector, your wiring is put in the wrong order or the motor is a fault one.īefore you check the wiring of the stepper motor, if you don’t have any experience you’ll want to follow a reliable video guide that gives you the know-how. To check this you can hook the extruder stepper motor to your X carriage output header connector then home your X axis. It’s possible that you received a stepper motor that is faulty. This reason is unlikely because stepper motors are so robust, and are designed to last longer than a 3D printer’s lifespan. You’ve received a faulty extruder motor or it’s past its time It needs some force to get it rolling, but once it’s moving it moves a lot smoother without the need for as much inertia. Think of it like the force you need to move a bowling ball. This is because the inertia the motor needs to turn has to be similar to its own inertia. When you are testing your motor and trying to get it to turn, it does so best when it has filament to actually grip it. This can occur if you have a replacement stepper drive that you just installed, but didn’t do properly. Once the connections and currents are in order, your motor should be able to get enough power to start turning fully rather than just vibrating. When a motor vibrates, what it means is it’s not receiving enough power to move past its initial position so the motor is just moving very slowly. In some cases your current is rated lower compared to your other motors so you would have to increase the current. The next most common problem you are likely to be facing if it’s not the wiring is around your currents and voltage. The current is too low to give enough power for it to turn fully It’s possible the color coded wires were put together in the wrong order from the manufacturer, but this reason is unlikely. Once you check the measurements you’ll be able to rule out the wiring being your issue. You can use a multi meter to check if you have continuity on all of your wires. The first thing you want to do is check the cables and whether your connectors are in good condition or crimped. The most common problem that I’ve seen people have when dealing with this issue is to do with the wiring being incorrectly plugged up. Your extruder motor wires are mis-wired or crimped badly Your extruder motor will vibrate and not turn generally due to one of these reasons: 1. It’s not an ideal situation to be having but I’ve identified a few causes as to why this has happened to some 3D printer hobbyists out there. You can even get an extruder motor that stops mid print or starts to not work. Some people describe their extruder motor movement as twitching, juddering, shudder, pulsing and even jitter but basically it’s just moving and clicking back and forth very fast.
