7i97T with Mesa CT- Desn't seem to be outputting an analogue signal.

Dont know what went wrong with that last one. 

None of the PWM enables are true (and all PWM values are 0)
So no analog output is possible:

30 bit IN FALSE hm2_7i97.0.pwmgen.00.enable <== joint-0-enable
30 float IN 0 hm2_7i97.0.pwmgen.00.value <== joint.0.output
30 bit IN FALSE hm2_7i97.0.pwmgen.01.enable <== joint-1-enable
30 float IN 0 hm2_7i97.0.pwmgen.01.value <== joint.1.output
30 bit IN FALSE hm2_7i97.0.pwmgen.02.enable <== joint-2-enable
30 float IN 0 hm2_7i97.0.pwmgen.02.value <== joint.2.output
30 bit IN FALSE hm2_7i97.0.pwmgen.03.enable
30 float IN 0 hm2_7i97.0.pwmgen.03.value
30 bit IN FALSE hm2_7i97.0.pwmgen.04.enable
30 float IN 0 hm2_7i97.0.pwmgen.04.value
30 bit IN FALSE hm2_7i97.0.pwmgen.05.enable
30 float IN 0 hm2_7i97.0.pwmgen.05.value
30 s32 OUT 0 hm2_7i97.0.read-request.time
30 s32 OUT 134983 hm2_7i97.0.read.time

Note that on initial setup of analog servos you will need to widen the following error limits
as you will likely trigger an immediate following error with such narrow limits

I would start with say 10 mm for FERROR and MIN_FERROR. You may also find that
you get an instant runaway because the feedback polarity is backwards.
YOu fix the by reversing the sign of the PWM scale
 

Thanks tons PCW,
halcmd show all > all.txt is an excellent tool, and your explanations are brilliant.

Its taking me a while to figure out what each item does and what we are achieving but the cogs are starting to mesh in my brain

I might have to finish work early today and do some more digging.

Thanks again,

Hi PCW.

I believe I have found an error in the mesaCT's hal file... but I could be wrong (I have just been comparing axis and trying to figure out how these files work)

Can you confirm that the highlighted joint reference is wrong  

This is X Axis, joint 00
 

And this is Z Axis, joint 02. Should the highlighted say 2 rather than 0?
 

Edit. If the highlighted is wrong, looks like Mesa CT was correct for joint 00 but it has this error for joints 01 and 02, for PWM scale and Encoder scale.

If encoder 2 is assigned to joint 2, then yes, that should be [JOINT_2]

I am being a bit vague because there is no fixed mapping between
hardware=encoder/PWM/stepgen etc and joints. 

That is great thanks mate. Makes sense to me now. Not sure how to tag people in these posts but I'll try inform JT of the issue.
