I have almost no idea what you are trying to do, but you are "net"-ing hypot.0.in0 twice there. I doubt that makes any sense.

Kenneth,

Are you still trying to display the combined velocity for all the axis?

Again, this is all you need... put it all in your postgui hal file.

loadrt mult2
addf mult2.0 servo-thread
setp mult2.0.in0 60
net ips-in mult2.0.in1 <= motion.current-vel
net ipm-out pyvcp.feed-rate <= mult2.0.out

All that other stuff was used/needed before the magic pin motion.current-vel was created by the developers...

sorry, misprint.

net feed-zero hypot.0.in0 <==
net feed-one hypot.0.in1 <==
net feed-two hypot.0.in2 <== motion.current-vel
net feed-output hypot.0.out ==> pyvcp.feed-rate

yes i am. i did get that to work(thanks). but was looking at something andy said to try.
trying to learn this stuff a little at a time:)

this works fine

setp mult2.0.in0 60
net inchPsec-in mult2.0.in1 <== motion.current-vel
net inchPmin-out pyvcp.feed-rate ==> mult2.0.out

when i use the below and i have offsets, it shows the offset.
axis dro shows 0(zero) and my panel shows .125(x offset).
so this is more complicated then connecting with these
three lines ? would feedcomp.N be better ? not sure how it
works and i'm guessing what it does

setp mult2.0.in0 60
net inchPsec-in mult2.0.in1 <== motion.current-vel
net inchPmin-out pyvcp.feed-rate ==> mult2.0.out
