Re: RE: emc help with home

The only confusion that you might still have is that you need to edit the
specific .ini file that is mentioned in the first few lines of the .run
file that you are using. It could be generic.ini, emc.ini, mini.ini or
mini-metric.ini in the standard BDI install. When you have successfully
done that, the axis will take off looking for a home switch.

You may have to edit the direction of that move. HOMING_POLARITY = 1 is
the most direct thing to change for that but first you should jog each axis
a bit and make sure that the numbers on the display go the direction that
you want them to. If not, change the sign of INPUT_SCALE = ?000 0
and OUTPUT_SCALE = ?000 0.000 before you change the direction of the home
move.

Well, here I sit composing a reply extolling the BDI virtues of Paul and
someone always beats me to it. Fortunately Tim didn't mention that Paul
is also a virtuoso of English bubbly, Czech beer, and the correct
definitions of esoteric English language words!

With the addition of a BDI download site in Finland, (Thanks Henkka) and a
Australian burner, (Thanks Andrew) my relation to the BDI is diminished
some. I do still have copies of BDI-2.04 for those who need. Simply send
your postal address to me off list and I'll ship to those who's postal
service is faster than their 450 meg download. Since I have neither a
burner nor a connection that permits that size of transfer, it will be no
offense to me if others in this part of the world want to burn and
distribute copies of BDI-2.07.

If you do want to provide this service contact Paul
<Paul.Corner@...> and I'm sure that he will place you on the list at
linuxcnc.org/bdi.
