Your pestersomeness is a typical thing with new users. After a bit you get
everything setteled out to your satisfaction and then they get real quiet.

The easiest thing to do is to call me - 906-875-6692. I will be out until 4
or so tomorrow.

Excuse me for yelling but there are a couple of things that really need to
sink in. If the letters are RED it means that your limit switch polarities
are backwards in the ini file. There is a section in the handbook that deals
with setting up the ini like you need to do. Until you see YELLOW letters in
the position displays when you start up the emc you can not do anyting else
except press lim oride and then you get just one move.

Once you have yellow letters you can press home and it will home out the
active axis. It's the one with the little box around it. If when you press
home, the axis starts to move and just keeps on going, then you need to
reverse the home switch polarity for each axis. A correct home switch
polarity will turn the position display letters green when the switch is
tripped.

You will want the home switches in parallel if normally open or series if
normally closed. IMHO pin 10 is not used so disconnect the switch.

There is one other thing that seems to trouble some when they start out. You
may think that you are editing the correct ini but the real one is referenced
on about line 27 of the run file that you use. If you are using emc.run then
look in it and see what ini file is referred to on that line.

Now max velocity is set in the task portion of the ini and it is in units per
second. So a max velocity of 1.67 is 72 ipm if you are using inches.

Sorry for your frustration but you have a very powerful and configurable
controller in that box. It will take you a while to get the hang of it.

Hope this helps.
