Is there any significant difference (in rapid moves) by running the machine
with 7i43-P or 5i20?
The 7i43 and the 5i20 can both command movements of much higher speed
than any reasonable machine can move.
Really the only practical differences between them is how they

That statement was already in my .hal file. But, I did comment out the
'motion.motion-inpos' line in the postgui.hal file and that did allow EMC to
run. Thanks for the suggestion and I'll keep plugging away.

So let's say you have two drives, two motors, and two home switches on the

synchronization. The control needs to be aware of the two motors and needs
to home both at the same time. While homing, we need to
So, are you saying that it can't presently be done because no one has
written the hal components to do it?
I have searched the archives and found very little.
FWIW - this machine uses steppers and no encoders.

Thanks Chris and Kirk. EMC will load on my desktop with the change. Now
I'm headed out to the shop to see if I can make this work in the real world.
Thanks again.

Len,
steppers makes this problem very easy and it has indeed been discussed
before.
Searching on the term two motors I was able to retrieve a number of my
own posts about this.

No, actually I do not believe any new HAL components are needed. You
need an and gate to detect when both home switches have been tripped.
