I'll check these out, I suspect, as I told Andy, that I didn't know what 
I was doing, but my pushbutton code fouled up my thinking as I tried to 
get that right.  Its been an "interesting day" so far.

Thanks Sebastian.

I do, but didn't realize the jog-count data needed to be massaged down 
to /1000th of a red hair. I set scale to one, which meant machine units 
according to the manpage for motion, whereas I thought it was the scale 
for that axis from the ini file. If I leave the math alone, then scale 
becomes .38933 for X and .45894 for Z.

I fed both inputs an enable signal, and set both scales for x to 1, and 
it ran to the mechanical crash point and sat there banging on it till 
the timeout expired. Poking the esc key was useless.

Re-reading man 9 motion tells me its machine units which is inches, 
whereas with my prior math, the scale, if I leave all the previous math 
alone, s/b the recipricol (SP? my spell checker sucks dead toads thru 
soda straws, default debian big_en) of the axis scale setting. The 
number I developed was for the number of microsteps. to move .0002" as 
the slowest step, and thats several inches by the motion definition.  
Duh. Dumbassed old man even. I can get rid of some math if I leave it at 
1, and just feed motion the same data being displayed in my post-gui-hal 
pyvcp panel stuffs.  And the pi will thank me.  That will take me about 
as long to excise that as it did to write it. :( Tomorrow maybe...

Re: [Emc-users] No response to jog data in

We have a pair of tests in the test suite that verify wheel jogging of 
joints and axes.

And here's how the HAL circuitry is hooked up in the axis case (the 
joint case is similar):

I have problem with jogging for one of the axis/joints, it works with keyboard 
but not from GUI. Someone suggested this problem was bug in GUI which have been 
fixed. MDI work OK.

I thought you had set up all sorts of clever HAL logic to drive the
jog-scale from the encoder?

Well, halshow won't let me set joint.0.jog-enable, but setting the 
axis.x.jog-enable sets both.  But still no machine response, and I note 
that both axis.x.jog-scale and joint.0.jog-scale are zero.  Can, since 
I've already done the math in my own code, assume that a jog-scale 
setting of one (to whichever one I am allowed to set, axis.x.jog-scale I 
expect) would be correct?

Or is there yet another "guard dog" to be fed & petted here, and under 
what conditions?

In the event it works, and the timer times out, zeroing the encoder etc, 
and the data being sent to jog-counts drops to zero when that occurs 
since the timeout resets the encoder, I assume I should drop the enable 
before the jog-counts drops to zero at the end of the timedelay?  Or 
should I not clear the encoder because motion remembers it and acts only 
on the new difference.  That would get rid of 4 or 6 lines of hal code.

Thanks Andy.

Depends what you want to jog.

Both, or just the latter?  Since your conversion script has been run w/o 
errors, I was a bit surprised to see the axis stuff left in the halmeter 
selection window.

Thanks Andy.

axis.L.jog-enable and joint.N.jog-enable need to be set.
