Looks like a bad stepper motor.
I would suggest checking by removing the extruded motor and seeing if it still works. If the motor is the same as your x/y motors, you can also swap the e-motor input to one and ensure it’s not something upstream.
(It could also be motor voltage, but that’s far less likely unless you were tweaking things,)
Is this sudden? Has it worked before?
If it was worked but suddenly started acting like this, It could be that the shaft of the stepper is broken or otherwise not connecting properly to the extruding gears.
Could also be a dead channel on the driver or broken wire for a set of the coils in the stepper.
It started today. I went to make them move just now and is moved a bit then when I told It too again it's shaking again.
I had a similar issue and it was a bad stepper motor. The bearings on these are just wide open and a bunch of filament dust had worked it's way into them. Turning the motor shaft by hand you could feel it get tight at certain points in the rotation. I just swapped in a new motor but you may be able to clean it out if you want to save the $9.
I would start by disassembling the extruder and see if the motor rotates properly. If it doesn't, then check wiring from driver to motor. if wiring is OK then it's probably the driver that's dead. edit it could also be a dead stepper motor, try running it from a different driver to see if it works at all.
If it does move properly when disassembled, check shaft that connects it to the gears.
