Mesa 7i96 with SPINX1 to control spindle speed

This is when the spindle should be running, you can see the changes:
 

The ini file PID values are incorrect for a spindle
They need to be what I posted before:

Oops never mind, I was looking at the wrong PID channel

but:

23 float IN 1 pid.1.command <== spindle-vel-cmd-rpm

The commanded RPM is 1!

You should probably set this to all least 1/2 speed (1400) for initial tests.

Also:

23 s32 RW 0 pid.1.do-pid-calcs.tmax

The 0 time means that there is a missing addf for pid1

The missing addf means the PID 1 output will be stuck at 0

 

Here is another file with the speed increased a bit

    23  float IN            301  pid.1.command <== spindle-vel-cmd-rpm
    19  float OUT           301  spindle.0.speed-out ==> spindle-vel-cmd-rpm
    19  float OUT           301  spindle.0.speed-out-abs ==> spindle-vel-cmd-rpm-abs
float           301  spindle-vel-cmd-rpm
float           301  spindle-vel-cmd-rpm-abs
    19  float RO            301  motion.debug-float-0



That was just turning on before. It does increase when I press the + in LinuxCNC, but still no change in the value

29 float IN 0 hm2_7i96.0.pwmgen.00.value <== spindle-output

Yeah, that will stay at 0 until the missing addf is fixed:

addf pid.1.do-pid-calcs servo-thread

Any idea what the addf should look like? I can add manually and test it. Almost all the documentation is geared towards parallel port or drastically different cards and setups.

addf pid.1.do-pid-calcs servo-thread

Makes sense, but didn't seem to fix anything. value is still at 0.

29 float IN 0 hm2_7i96.0.pwmgen.00.value <== spindle-output

 
 

looks like you have the spindle turned off:

23 bit IN FALSE pid.1.enable <== spindle-enable

or

net spindle-enable pid.1.enable

should be

net spindle-on pid.1.enable

Made this change

#net spindle-enable pid.1.enable
net spindle-on pid.1.enable

Now the value seems to be working. I will need to check my SPINX out, but at least the signals going in look like they are working now.

Also attaching the latest hal file for  BigJohnT to look at. 
 

I think what fixed it to work was adding
addf pid.1.do-pid-calcs servo-thread

and the change for the enable
#net spindle-enable pid.1.enable
net spindle-on pid.1.enable

I do notice my direction LED comes on and doesn't turn off, whether enabled or not, is that kind of expected?

Thanks a bunch to both of you. John, once you have something else for me to test, just let mw know, I understand if it may take a little while.
