Servo Wiring and Tuning detailed How To example Mesa 7i77.

I would check

hm2_5i25.0.7i77.0.1.analogena
and
hm2_5i25.0.7i77.0.1.analogout0
with halshow

if analogena is true, analogout0 is +10 you have no real-time warnings
(and OUTPUT_SCALE is 10) and you don't get close to 10V on the 7I77
analog output 0 (7I77 TB5 pin 4 relative to TB5 pin 3) Then there is likely a
problem with the 7I77

Hi I did the test with no result and after purchasing another 7i77 this cured the problem, now I`ve just got to learn servo tuning ??

Changed the title to reflect wiring since a lot of detail is about wiring and testing practices.

Great! Was wondering where this went!

Now, can someone edit this older post to reflect the new url: forum.linuxcnc.org/10-advanced-configura...7i77?start=80#143677
