Add Axis

hi...new user here...trying to add an axis..copied/pasted /edited...still something not right....not sure what I am doing wrong..

Thanks for any help

Rick

Sorry....just found the error...missed one b reference...Thanks!!!

Hi...I copied a working axis as far as being able to jog with no error...but when I jog new axis (U)...I get Joint follow error...not sure what I am doing wrong...I tried to switch pins to another working axis and still had problem with U...other axis still worked after switch pin...??

One way to debug this is to widen the following error limits
and then plot the commanded and feedback joint positions
with halscope.

So I am new to lcnc...will have to learn halscope...in the meantime out of curiosity...what is the actual feedback looked for that results in error when not found?...

Thanks!

net u-pos-cmd <= joint.4.motor-pos-cmd
net u-pos-fb <= hm2_7i96s.0.stepgen.07.position-fb

I left shop for today but just noticed this in my hal...no reference to new axis (U)...would that cause the error?...thanks!addf hm2_7i96s.0.read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pid.x.do-pid-calcs servo-thread
addf pid.y.do-pid-calcs servo-thread
addf pid.z.do-pid-calcs servo-thread
addf pid.a.do-pid-calcs servo-thread
addf pid.s.do-pid-calcs servo-thread
addf hm2_7i96s.0.write servo-thread
setp hm2_7i96s.0.dpll.01.timer-us -50
setp hm2_7i96s.0.stepgen.timer-number 1

# external output signals

Yes, you are missing the:

addf pid.u.do-pid-calcs servo-thread

so the "U" PID pins are there but they are  not functioning

What a relief!! So in terms of unreliable hardware...its me!!

Thanks again..glad to be able to move on...

Thanks again!
