z-axis shaking

Hi!

It´s something wrong with my Handibot. When it´s moving on the y-axis it´s starts to shake.
You can´t make anything because it shaking to much so everything looks like zig-zag. I don´t think it´s the motor, it must be the slide. Have you heard of this before? What can i do?

Regards,

May well be the slides, disconnect the Y axis drive and then gently push the Y back and forth. It should push smooth and easy.
