Re: Re: Need Zero Help!!

Ed, Alan

If you do not have home switches and are running with those pins closed
in your ini file, you can just hit home for each axis when you get where
you want 0.00 to be.

I'd use the script named Set_Coordinates that is under the scripts menu
in themc. It has teach for all axes that you have defined. If you leave
g54 alone and use g55 for your first coordinate system you can switch
between by just placing a g54 or g55 in the starting block where you want
the change to be active.

If you are going to use g92, don't forget g92.1, g92.2 and g92.3. I
described the effects of each of these on my grizz in a paper that is
available in the dropbox at www.linuxcnc.org. It's available in three
formats

g92test1.lyx
g92test1.pdf
g92test1.ps

Using this code can be a bit tricky.

Hope this helps (not zero help)
