Take a look at this: http://www.cutting.lv/fileadmin/user_upload/axis-modified.py It implements new HAL pin axis: axisui.set-world-mode I think that its name is self-explanatory. All that is left to do is link it something in HAL. My experience tells that best results are achieved by connecting it toall axis.N.homed pins (through and2 modules although for me it is easier to create and4 or whatever the number of joints is). It behaves pretty nicely: 1) $ key still works so user can switch back to joint mode manually, if needed; 2) having axisui.set-world-mode set to "true" by whatever HAL magic does not disturb user activities in previous point; Viesturs ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
