i cant move the axis

I've uploaded the sjfw firmare on the gen4 through replicatorG, I've configured the printer through the reprap.xml file as described on the firmware site. I've selected the sjfw machine: connected it succesfullt. In the control panel the temperatures seem to work fine but if I try to move the axis in the replicatorG terminal i get an error: 2 lines with: error the axis are not configured, what should I do?
Thanks

Grab tom.gcode from here:

and print it to configure the firmware.
