Newbie- Homing Question

[CanAm1]

Hello All,

Just got the homing switches and relays installed on my 12 x 12 and tested. Right now I do not know what this will can me, but time will tell.
Up to now what I have been doing is using G55 all zeroed out for my reference home. This just happened to be located at the center of all 3 axis. I would then switch to G54 for my offsets and such. Worked OK for me, but now onto the home switches.
I have a couple of questions: First, I have the home switches located at the far positive end of each axis. Once the machine found the switches it changed the readings to zero. This means that all measurements would be negative with respect to home. Right now the config. page shows the home position is at 0 for all axis. Is this why when it finds home it sets things to zero? If I change this input on the config. page to say +6 inches (half of my travel for x and y) would the machine set home at +6 inches? I could then hit the zero button and the axis would go to the center of travel?
Thanks

Mark

I think that only worked do to pure luck.

If you're talking about the "Home Offset" in Config >Homing/Limits, then yes, yes, and yes.

Gerry,
I think we are talking about the same thing.
Under Config > Homing/Limits: the G28 Home location coordinates box???

Thanks

No, use the column labeled "Home Off."
