Hello to all the gurus, I am facing a problem with my new built CNC platform. Before I describe my platform let me share a bit about my design. The platform is about 40"x40" square using the ABEC7 bearings from CNCRouterParts (http://www.cncrouterparts.com/product_info.php?cPath=21&products_id=33) to run the X and Y axis. The bearings run on 1/4" thick steel. I have a single lead screw driving the Y-axis that is positioned in the middle.
I noticed that when I cut a 6"x3" 1/8" thick aluminum from sheet, the squares are are off by at least 1 degree that lends me to believe that my Y-axis deflects when cutting. My question is, can this deflection be removed if I move to round linear ball bearings running 45" on a 20mm shaft? I am trying to hold back on running my Y-axis using 2 lead screws one at each end and using 2 stepper motors. Any thoughts/opinions highly appreciated. Sam. ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
