All,

Never mind. Working now. I swapped 7i33 boards. Should go back to the other 
board  and make sure I was doing exactly the same thing.

Regards,
Eric

[Emc-users] Forcing analog motor reference

[Eric H. Johnson]

All,

I am not seeing the analog output values change on the Mesa 7i33TA daughter 
board from the default 7i43-big configuration. I should see it across pins 9 & 
10.

This is from Linuxcnc 2.8.0-pre1 running on Xubuntu 12.04.

I tried decoupling the analog output from the configuration as follows:

Commented out:
net motor.00.command pid.0.output => hm2_[HOSTMOT2](BOARD).0.pwmgen.00.value

And replaced with

net MotorXval => hm2_[HOSTMOT2](BOARD).0.pwmgen.00.value

Not sure if the enable is necessary, but is working as the amplifier does turn 
on.

I would think that if I then do

halcmd sets MotorXval 0.5

I should see the voltage output across pins 9 and 10 change accordingly. I am 
not seeing any change. Am I missing something in the way I am trying to test 
this.

Encoders, and basically everything else seems to be working.

Thanks,
Eric
