Hey, during one of my recent 3d prints the extruder motor system clogged up and the stepper promptly ceased to move filament.
The stepper still makes the correct noise and moves, but there is no output from the gear box on top of it. This is what the gearbox looks like now - minus the planetary gears because they are all in good shape:
As you can see, the sun gear rotates around and slides off the axle easily. The axles still outputs power, so I know the problem is from the sun to the planetary gears. Now, I’m guessing the sun was pressure fit? Or welded, or something. Whatever the case, I know it should be attached to the axis. Since it slides around now, do I have any hope of fixing it?
