You saying that it should look like this? net Xindex-enable axis.0.index-enable m2_5i23.0.gpio.P2.005.in Result is this Starting EMC2... m5i23.hal:99: Signal 'Xindex-enable' can not add I/O pin 'axis.0.index-enable' Shutting down and cleaning up EMC2... Tried this net Xindex-enable axis.0.index hm2_5i23.0.gpio.P2.005.in Got this Starting EMC2... m5i23.hal:99: pin 'axis.0.index-in' does not exist Shutting down and cleaning up EMC2... The only way it will take it is Xindex-enable hm2_5i23.0.encoder.00.index-enable axis.0.index-enable But Peter send this >No, index-enable is not the index input (thats the GPIO pin Sebastian >mentioned) >index-enable is a bi-directional pin that enables the hardware index logic if >set, It is cleared when a index event occurs. Found this on IRC 13:34:02 <SWPadnos> hmmm - those are the same in both the stock univstep and my config 13:34:38 <SWPadnos> strange - I thought the tool prep loopback was added to all the configs 13:38:13 <rayh> axis.0.index-enable is the only index pin available today in head. 13:38:35 <rayh> It may be that jmk changed the name of the pin when he got it working last week. 13:38:46 <SWPadnos> I'm looking for the change that removed index-pulse-in from all the axes 13:38:48 <SWPadnos> could be 13:39:25 <SWPadnos> yep - removed index-pulse-in, added index-enable 13:40:15 <rayh> okay that explains it. is it grep -r time on the configs directories 13:40:31 <SWPadnos> I'm not sure. it seems weird to have index-enable, but no index 13:40:39 <SWPadnos> nothing to enable 13:41:20 <rayh> I though it a bit strange which is why I simply commented out the links. 13:41:56 <SWPadnos> yep - just did that in my config. I'll ask JMK about it tonight 13:42:13 <SWPadnos> not sure what he was thinking (and I haven't read the encoder canonical interface yet) So How is the index pulse to be sent to EMC? ------------------------------------------------------------------------------ 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
