Oh, I thought HOME_IS_SHARED meant the home was shared with another axis. I'll give that a try. Neil On Tue, May 4, 2010 at 12:03 PM, Stephen Wille Padnos spad...@sover.net wrote: Neil Baylis wrote: [snip] Here's the Homing section of my .ini file: HOME_SEARCH_VEL =       -1.0

No, same problem. With HOME_IGNORE_LIMITS = YES, it sails right past the home/limit switch and hits the hard stop. With HOME_IGNORE_LIMITS = NO, it stops at the limit, complaining that it hit a limit in homing state 5. HOME_IS_SHARED seems to have no effect on this. Note: I tried monitoring

Thanks Steve. I made 3 halmeters as you suggested. They all register FALSE, even when the GUI is showing the position in red when I hit the limit. Just to make sure halmeter is working, I added another halmeter on axis.0.motor-pos-fb and it showed the same position as the GUI does, updating

OK, I've posted what I think is relevant. If there's a file missing, let me know. I posted the output of halcmd show twice, once with the machine off the limit switch, and again with it on the limit switch. I omitted the .tbl and .var files. These files are edited versions of originals from the

Indeed, that was the problem. Now, the halmeters show the limit switch as expected, as well as the home signal. The homing sequence works correctly. (I changed HOME_IGNORE_LIMITS to YES, and it does the expected thing). Thanks everyone for your help and suggestions. Neil
