My only experience comes from reading the mailing lists, forums and IRC. I have never actually seen a gantry. There is a kinematics which allows you to independently home two joints on the same axis to independent home switches. Called, unsuprisingly, "gantrykins" it lets you map more than one joint to each axis, and as long as it is configured correctly the two motors will home independently but simultaneously. It has a number of issues which make it generally more trouble than it is worth (mainly to do with world-mode jogging, because as a non-trivial kinematics it makes a distinction between world-mode and joint-mode) The problems with gantrykins are, as far as I know, all addressed in an alternative one-axis -> many-joints kinematics called "gentrivkins". Unfortunately gentrivkins only works in the joints_axes3 branch of LinuxCNC (which is currently quite up-to-date, as far as I know, but isn't available as a package) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
