No. hal_manualtoolchange treats its .change_button input pin exactly like it treats a click on the button in its GUI window. The intended use of that pin is for if you want a physical button on the machine's control panel to let the operator signal completion of a manual tool change. You'd bring the physical button into HAL (via a parport input pin or a hostmot2 gpio input or similar), and wire it directly to the .change_button input. Then when LinuxCNC executes M6, hal_manualtoolchange will pop up its GUI window, and *either* a mouse click in the GUI or pushing the physical button will signal to hal_manualtoolchange that the tool change is complete. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ 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
