I've also ordered some of the QSE159s plus some of the recommended LED's 
to go with them.  My probe is due in tomorrow but the testing will have 
to wait since it appears my new SkyFire LinuxCNC machine has turned into 
a kit instead of ready to run.  I miss measured my Door opening to my 
shop.  This Mill will not go in fully assembled, so it has to be taken 
apart and reassembled once the pieces have been moved into my shop.  Not 
quite as much labor as retrofitting a manual mill, but it will 
definitely get me close and personal to all the components.
