I think I did. The steeper motor is running. Any other way to check?

Sure. Take the fan and cooling sink off. Remove the stepper if you want or you can just leave it on the cooling bar. Look at the feed guide and the roller. Make sure they are lining up. Let me know if that was the problem. If not you might need to remove the extruder head and check the teflon tube if you have not done that.
