Hi all,
I just updated a machine from EMC 2.3.0 (Ubuntu 8.04) to the current version
2.4.6 (Ubuntu 10.04). Most of it ported over pretty seamlessly. The one
problem I have not figured out is why axis jogging is reversed from the
prior configuration. Everything else regarding motion still seems to

Scott,
You got a lot of replies on a topic with a lot of fog surrounding it, but I
need to chime in here so you don't repeat my mistake: I broke a motor coupling
about a year ago during servo tuning. The sound almost scared the coolant out
of me!
I am no controls expert, but I now know why it

I'm in the shop working on this right now and am wondering how to verify the
PID loop is providing feedback to each axis. I've been using pncconf to

it would configure it to feedback automatically. However, since I've bee

The 1100M came both ways with glass scales (earlier model) then with
encoder feedback. Mine is the encoder variety of 1100M.

Scott,
That is some very good documentation...
I have a working BP series 1 with the Anilam 1100M conversion on it soon
to be converted to EMC2.
Do you have the drive tuning information that came with the conversion kit?
If you increase the following error will it not fault out? You may have
this is great to hear. thanks.

Before I had W3 in the up position, which enabled the pull ups on the
