Help - Z-axis not moving

I am getting no Z motion, X and Y home but Z does not move. Tried using manual commands they don't have any effect either. As a last resort I did a factory reset, but that did not help.

With power on the motor does hold position, but does not respond to move requests.

Any help or suggestions would be greatly appreciated!

Handibot v2.0 running Fabmo v1.7.2

Thanks in advance,

One thing that I've seen cause this before -- is the move speed for the Z axis being set to zero.
Try running a normal file with a move speed command at the beginning (This command shows up like "MS,3,1" in the header of the file)
or open the editor in fabmo (pencil icon) and type in the following:
MS,3,1
ZZ
MZ,1

This will set the move speed of the z axis to 1 ips, set the current z position to zero, then try to move the z axis up by 1 inch.

This had no effect, I took a movie of this and a motion test that I will forward via email at they are too large to attach.

Thanks in advance,
