When adding NML stuff wihch ultimately can be triggered from the GUI, I usually add a pin to halui (the HAL User Interface for emc2). Then you can trigger it from HAL, and it also proves the rest works as expected. It would be nice if you could add that.
PS: I'm gonna read the patch now :P Regards, Alex ----- Original Message ----- From: [EMAIL PROTECTED] To: emc-developers@lists.sourceforge.net Sent: Friday, February 15, 2008 4:45 PM Subject: [Emc-developers] 'Un-home' capability Dear fellow developers, The attached patch file adds the ability to un-home an axis (clear its homed flag), namely through the new [AXIS_n]VOLATILE_HOME ini file option, the EMC_AXIS_UNHOME NML message, and the emcAxisUnhome(int axis) call. See http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-02-14.txt and http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-02-15.txt on the discussion of "unhom*". After applying and (re-)compiling, setting VOLATILE_HOME to 1 for any particular axis will cause it to lose its homed flag upon ESTOP and OFF. The syntax for the milltask API call is almost identical to its homing counterpart. Setting the "axis" variable to n unhomes the n-th joint; setting it to -1, unhomes all joints with the permitting ini entry. Ditto for the NML message. jepler suggested that the ini file permit three possible values for VOLATILE_HOME: "never," "amplifier-off," and "estop." SWPadnos emphasized the ability to cause unhoming from a HAL module. It should be relatively easy to move the emcAxisUnhome calls around inside emcTaskSetState to satisfy the former. As for the latter, an "unhome" pin could be added to ioControl.cc (or halusr?) which, when triggered, cause it to send the EMC_AXIS_UNHOME packet. I implemented neither of the two in my patch because my original purpose was simply to provide the function calls upon which this feature could be further developed.
