I'm glad your motors are working. :-) If the .hal file that you posted loads without error, it looks to me like EMC2 is seeing the P3 I/O port correctly (otherwise there would be no GPIO output pins). For the outputs to work, you need to set the relevant .is_output HAL parameter to TRUE. Otherwise the pin remains an input. The mechanism for doing this is documented in the GPIO section of the hostmot2 manpage. <http://www.linuxcnc.org/docs/devel/html/man/man9/hostmot2.9.html#General%20Purpose%20I/O> Do the limit switches work? Try using halmeter to monitor the pins as you activate the limit switches. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
