Tomp,
I answered the question (and I quote Where can I find information
on using two encoders on an axis?).
I hope the wiki page is found useful.
thanks
Stuart

Stuart, the wiki page is indeed useful -- it compliments the hal
configuration nicely.

Stuart did you guys do anything unusual to tune the loop?
Did you ever run the machine without the linear encoder?
meaning can you compare the two techniques directly?
Cheers

Chris,
John Kasunich, Chris Radek, Jeff Epler and Steve Padnos are the
crew that tuned the axis with the dual feedback. I don't believe they
did anything much different than normal tuning as if there was only
one PID and one feedback.
I haven't run the machine much. It is in line to get
I'm designing a unconventional gantry router that will make use of the
rotatekins kinematics module. I've been reading all the manuals and playing
with axis (using a modified core_sim.hal). It would appear that the angle
(joints[5]) used in rotatekins.c defaults to zero, therefore it behaves
Kevin,
Go to http://www.mpm1.com:8080/GandL/configs/18_Feb_2008 and look
at the .ini file and the file the .ini file calls in the hal section.
They show how to combine the position feedback from two sources.
With your explanation of the machine you want to build I would
suggest looking at

This question seems to come up a fair amount wonder if a wiki entry is

What is your opinion of this technique now that you have tested it for a while.?

A wiki entry is ALWAYS appropriate. If it isn't in writing, it doesn't
exist; and a wiki entry is an easy way to put it in writing.

This is excellent -- I'll keep busy by digging deeper into hal (the
GL_servo.hal has my interest right now).
Thanks Stuart!

please read the information that was suggested closely

If I were able to use an encoder on the z-axis for position control
and
one on the motor (not directly coupled to the axis) for velocity control,
i think the ini file that was suggested has BOTH encoders connected as
