You need to measure it with dial indicators, gauge blocks, anything that can accurately tell you how far the axis has moved. I haven't done anything with screw compensation, but I believe you need to pick a zero point, command a move, then measure how far the axis actually moved. You also need to move beyond the second point, then move back to the second point from the other direction to get the other direction data. This is what I found in the wiki: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Screw_Compensation -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
