Did you read the text in pncconf about homing- it shows when you are on an axis page and press the help key. help text changes for most pages when you press the help key.
I thought it did a decent description of the basics - it's old text so I could add more to it.

But it doesn't need to be at the origin or switch trip point. The problem seems to come from people thinking the contact with the homing switch is where home is. which is not surprising, as when you ask linuxcnc to home that's where it goes first. But it's where the machine stops _after_ homing that is actually home and it doesn't have to be the origin. You can of course set it up as you described, but that is only one of a million different ways. Here the two switch exmple show home at the origin and home at 3: http://linuxcnc.org/docs/2.8/html/config/ini-homing.html I might point out this is machine coordinates which most people don't normally work in. As I said homing is actually complicated - through linuxcnc's flexibility.

There could be only ONE home position and that's in my understanding the origin in machine coordinates. Or with other words: home position is where the home switch signals contact. > The home position was just set at 6" arbitrarily. That's what I said. But then the home position may not be called home position. It might be a workpiece origin, a reference point, what ever. > Homing is complicated! Not at all! But wordings and diagrams should be clear and understandable. Arbitrary positions should be marked as such. The current picture is misleading - especially if your unsure and look for help. It is a help page! cheers Reinhard _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
