TB6560 Configuration for CO2 laser - problem to set it up

[gsmiata]

Hi,

I bought the TB6560-3Axis about 1 year ago and finally found the time to get rid of the Moshidraw Board.
I have one os these standard chinese CO2 Laser.

Now I got the X and Y axis working with MACH 3, but I´m not sure how to connect the Z-Axis.
As far as I see, Z Output is 24 Volts, but on the old Board, there are only 5 V goint to the Laser.

Can anybody help me with that, has anybody a picture of his set up (board)?

Thanks and regards

Gavin
