Pay attention to head pressure and make sure your board is flat. Also use masking tape under the board. Careful, last time I had this problem I blew a X drive.

"Jerky Drive" I thought maybe you were trying to raise money for dried meat....lol

Is the sand paper tracking correctly, is it running straight on the rollers?

It never hurts to start with a very good cleaning too.

also make sure you don't have the adjustable rail (opposite of keypad) too tight and your material is smooth & straight on the edges (parallel too)

It will happen if the board looses contact with the brass roller, rapidly rocking back and forth.

A rolled under belt will cause this.

A un level head will cause this.

A board missing a chunk of wood at the brass roller contact area.

Sawdust has gotten inside your gear box.

Missing tooth on the X Gear.

Head pressure too loose.

Board jamming and trying to self clear. Due to a tapered board and or right side guide too close.... I keep it a Quarter Width away.

Just a review of all the great ideas from above.

WOW a Troubleshooting Question..... I was having withdrawls... Feeling like the Maytag Repairman....
