For those unaware, emcprobe is a utility that makes emc behave like a=20
pantograph.   You need to have a probe tip mounted in the machine chuck a=
nd=20
connected to the probe i/o line on the emc parallel port.

The source is for the emcprobe utility is in the sourceforge CVS reposito=
ry.
I am still working on the documentation.   If you have a system where you=
 can=20
build emc source then you could use the "browse cvs" feature  of sourcefo=
rge.=20
and download the code.  =20

emcprobe.cc is in the /src/task directory   (you will also need the Makef=
ile=20
from that directory)

I am hoping to get the documentation done soon and emcprobe will be out i=
n the=20
next release of emc.

To run emcprobe,  you need to create an initilization file that tells it =
about=20
the region(s) on the machine table to probe and some other info like what=
=20
polarity the probe tip is.  I will put a sample init file in the docs.  I=
 can=20
email you a sample init if you want.

Next, fire up emc,  confirm your probe works with the existing emc gui me=
nu=20
item.  Zero your machine, mount the item on the table, and then open up a=
=20
console and run emcprobe -f  initfile.    Emcprobe will then take control=
 of=20
the machine and run the probe through the region(s) specified.   You can =
hit=20
control-c to abort emcprobe.

Emcprobe will then output a g-code file representing the surface probed. =
 It=20
will also display the probed coordinates on the console as it runs.

Emcprobe can take a long time to run.  For example a 3"x5" region probed =
on a=20
=2E1" grid can take several hours to probe. =20

I also put into cvs some g-code utilities the are under /src/ncutils.   T=
hese=20
utilities perform various transforms on g-code files.  You can rotate, sh=
ift,=20
flip, merge g-code files with them.   These utilities compile under Borla=
nd=20
for Win OS or under linux.  These are well documented in the cvs source. =
=20
There main intent was for use with the g-code produced by emcprobe, howev=
er=20
they evolved into more general use.  I use them with g-code from other=20
programs as well and find them quite handy for lining things up on the=20
machine. =20
