Hello -
Its me again, still having problems ...
So I got Y and Z to jog, seems like the values for
FERROR for the X axis are not the same as those for Y
and Z in the /etc/emc2/sample-configs/m5i20/m5i20.ini
maybe that is not a big deal but I made them all the
same and still no jog on X-axis, getting following
errors.
My encoders have Index output but this is what I am
seeing:
bit FALSE Xindex
==> axis.0.index-pulse-in
<== m5i20.0.enc-00-index
bit TRUE Yindex
==> axis.1.index-pulse-in
<== m5i20.0.enc-01-index
bit TRUE Zindex
==> axis.2.index-pulse-in
<== m5i20.0.enc-02-index
makes no sense ... I have tried swapping cables and
motors without any luck. Help !
