Hi, Positioning the laser with magnets seems like an invitation to disaster. The laser WILL get bumped or jiggled out of position. Hopefully, the out of position would result in the machine not moving instead of moving to the wrong position.
Using the laser to establish rough position (therefore eliminating the need for a limit switch) to allow homing from the startup position seems "reasonable" if you can determine the laser position is repeatable enough to catch the encoder index mark on the correct rotation. To me, if you plan to home the machine, this sounds like a solution in search of a problem although I don't know the complexity of installing limit switches. thanks Stuart ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
