Chuckle, been there, done that. But you can't tell these folks to get the 
hell out of your hair so you CAN apply basic troubleshooting.  They you 
see, ARE the boss, and can't seem to understand that their constant 
meddling with your train of thought is costing them money.

About a year into my tenure as the CE at WDTV, such a situation developed 
where an important piece of gear was down.  Something to do with news, 
which is a tv stations biggest cash cow.  So the GM and the News Director 
took turns, coming into the shop about about 6 or 7 minute intervals to 
give me a sermon on just how quickly they needed it back among the living.  
This went on for about 3 hours, right thru the usual lunch time, so about 
2:30 I saddled up and headed out to find a couple cheeseburgers etc.  I 
purposely sat down and took my time eating them, read the paper and 
ignored the pager which was going off at 3 minute intervals.  About an 
hour & a half IIRC.  When I did get back, I found the GM, purple faced, 
sitting on my work chair in front of the bench. At that point I pre-empted 
his blowup by turning around and walking back out. He followed me as I 
threw a leg over my GS-1000-G & made as if to leave again.

That finally got his attention.  The only guy who could do him any good 
yet today was about to drive off & go get a 6 pack & take it home.  Then & 
only then did he actually start to listen to what I had to say.

I told him in no uncertain terms that if I went back into the building, I 
was to be left alone to do what I do best, and that I would come and tell 
them when I had found the problem, and if I had the parts, when it would 
be working again.  And that if _anyone_, even the telephone, bugged me 
before then, I was gone.  You go back into the building, do whatever you 
have to do to assure that, and you come and tell me.  I looked at my watch 
and said you've got 10 minutes before I push the starter button.  He was 
back in 6.  I went back in, settled in to find it, which turned out to be 
3 parts actually because some bypass caps had opened up and the noise on 
the supply rails was substituting for a memory chip with an open in the 
top half of its totem pole style output driver.  Took about an hour to 
walk thru the logic and find the bad bypasses, which when replaced, got 
the digital noises down to where the scope could tell me the memory chip 
was bad.  The memory chip was an older NMOS technology and the only chip 
in the house with the same footprint was a much slower rated 6116, done in
CMOS for vanishingly low power consumption.  I put it in the socket, the 
circuit was happy, and it was back in circuit working about 10 minutes 
before the 5:30 news opened. Nearly 15 years later when a newer, made 
prettier video, replacement was bought, it was still working when we 
unscrewed it from the rack.

But it didn't take long for that lesson to be forgotten.  I had to do a 
refresh 3 or 4 times over the next 4 years.  After that, I had a new GM, 
and 3 years later yet another, but that one is still there and we do 
understand each other.

Its sorta funny, I served as a traveling firemen for Mr. Withers off & on 
for the next 10 years after I "retired".  We were on his airplane headed 
for his station in the Michigan UP when the conversation drifted over to 
that, and I related that at one point Smitty was going to fire me.  Smitty 
was GM #2. Russ looked me right in the eye and said he couldn't do it 
because he would have had to clear it with me. I asked when did I achieve 
that status?

When you called Mel's bluff (GM #1) in front of me about 2 weeks after he 
had hired you.  You've been honest with me which is a lot more than I can 
say about some who have worked for me over the last 45 years.

Russ always treated me well. When he needed help in Grand Junction, I had 
the use of his guest house next to his big house out toward the monument 
and the use of his personal new F150 4wd pickup & gas card.  I stayed 
there 3 times, for almost a year total. I air freighted a bunch of stuff 
home from the Sportsmans Warehouse as I was being quite well paid for that 
time.

Sadly, Russ passed early this spring. He turned out to be a good friend 
for nearly 30 years.

Cheers, Gene Heskett

BTDT, maybe 65 years ago.  Wound on a quaker oatmeal box IIRC, seems like 
I recall getting a 3" spark that burned a hole in my hand at least as bad 
as getting too close to the cap on a 1b3 tube back in tin tube tv days.  
Took about a month to heal, and I wasn't too sweet to heal then, average 
no stitches needed cut was 3-4 days.  Burned a pinhole all the way to the 
bone.  But I also got a little schmardter.  ;-)

Weather cleared but it blew the tarp off the work table, then added .4" to 
the rain gauge in about 10 minutes.  So I went back out & cleared stuff 
off with the air hose & managed to get some more done before the sprinkler 
turned my way again.  Not done  yet, but need to hit advance auto for some 
#10 ring lugs suitable for 14 gauge wire before they quit for the evening.

But see if the better half wants to go along & hit the steak house buffet 
for dinner.  No use making 2 trips.

I have that green when stopped too.  At some point I'll add an and2 to 
combine it with motion.spindle-on so that it will be red when stopped.
But tell me about this dual needle display? In the pure software config, I

That is actually what I am looking for Andy, thank you.

But I sure can't read that in the man page which is so small and concise 
it can't even be said to suck...

The relevant man page lines:

out is true if in1 and in2 are within a factor of scale (i.e., for in1 
positive, in1/scale <= in2 <= in1*scale), OR if their absolute difference 
is no greater than difference (i.e., |in1-in2| <= difference).  out is 
false otherwise.

A true mathematician would read that correctly, but not all of us can be 
said to fit that category. :(  What little algebra I got in the fraction 
of a year I did go to school as a freshman, was a total waste of time, the 
male teacher was far more interested in telling sexy jokes to horny kids 
than in actually teaching the subject.  Call me a victim, whatever, but 
had I been the school board, he would have been fired 3 days into the 
school year.  Maximum.  He was, IMNSHO, a sexual predator.

Now, since the man page also skips over difference, can you define its 
use?  Is it intended to be a "floor" function, as in at slow speeds where 
friction etc come into play, where the scale sets a very narrow window, it 
would allow a larger error while still reporting true?

Thanks Andy.

i'm also at a loss with the same idea ,
i'm looking at using the dual needle display , showing commanded speed ,

and if thats within bounds etc .

sure this near comp , should have an if zero then it's not good , it's just

or if a slight dif other than both 0 , then it's running , as i doubt in
this particular instance you would never get both inputs 0
perhaps a new component or this renamed specific for spindle may be a good

But if you want a percentage difference, that is what the "scale"
parameter is for.
use a scale of 1.05 and you have a 10% window.

[Emc-users] near module, Grrrr

2014-09-02 Thread Gene Heskett 
Hi all;

I thought I had come up with a way to scale the near.N.difference to the 
spindle requested speed.  A way to turn the button green if the difference 
was say 10%.

But near.N.difference is a parameter, and when an attempt is made to net a 
signal to it, lcnc goes boom & won't start.

I'll figure out something yet, but that wasn't it.

New spindle motor psu is about half done, I got rained out last evening.  
It seems sort of strange, instead of making a box for the transformer, 
this time the box is bolted to it.
