It would be nice not to put home switches on the machine if we don't have to. We have a nice feature for homing in the Granites, it would be nice to use it. I think we can just put a new Home button in the PYVCP panel which: 1)trigger halui.machine.off 2) toggles our Homing sequence via our GPIO pin (Granites home to stops) 3) waits for Homed signal 4) trigger halui.machine.on 5) initiates EMC's home just using index on all axes (EMC homes to true home position). Does this sound reasonable? -Tom ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
