Problem jet jts 250 sliding table

Hello!
I have the jts 250 jet, i have trouble adjusting the slide, it moves wrong. Can anyone help me? I’ve been trying to regulate for a week. I took it apart completely to clean and understand the problem. Anyone know how to adjust?
Otherwise I exchange the sled with someone who has a fixed extension wing.

Help me!!
