Basically, if you draw a centerline down the center of the hobbed bolt’s teeth, it misses the center hole down which the filament must pass in order to reach the hot end. The offset is about 2mm, which is significant since the filament is only 3mm in diameter.
The bodded bolt is set up in the following manner: large gear --> three “large” washers --> one “small” washer --> bearing --> printed frame --> bearing --> “large” washer --> locking nut.
Since I do not wish to cause more harm than good, I have refrained from attempting a f ix on my own. I believe that another washer should be added to the “stack” of four washers in order to shift the hobbed bolt into alignment.
