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

Hi all.I have taken a look through the forums here and had a heavy google search- I had a few leads but all parts of my code appear OK where others seem to have failed.I was trying to identify if it was my drives not responding to signal, my wiring being incomplete, or my HAL setup.. could be all of them but I am unable to pick up any output from the mesa board via multimeter or drive monitoring software.Please see attached- any assistance very much appreciated.     

Correct - there was no way of configuring the spindle using my card and mesa CT - But that was a hurdle to jump another day it should still work tho right? Or does it NEED spindle??

When linuxcnc is running and you expect an analog output
can you run:

halcmd show all > all.txt

in a terminal window and port all.txt here?

Hi PCW.

Attached. I cant do it while actually trying to generate an output as it errors within a moment due to movement error

edit to clarify.

When i look at halconfig and PWM enable and value,

00 and 01 enable when i turn on the machine within lcnc
I can jog X and get 00 to flash up a value. 01 and 02 do not do this (02 probably because its not enabled)

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 :-D

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.
