kanton, the motors may not be up to the task of raising the head, unless you have a really good counterbalance setup that minimizes the required lift force. The website that is associated with the ebay sale strangely no longer lists the package on their website. When it was on there, they said the steppers were "... over 100 oz in torque". I know this is well below what most guys are using.
Maybe it would be possible to use 2 of these motors on the Z axis? I guess you'd have to do the math and see if it's financially worthwhile to pursue it.
