[Emc-users] Determining scale

[Gene Heskett]

Greetings all;

Got a puzzle because with the 5i25, I have no base-thread.

But w/o a sample at base-thread speeds, its not going to be possible to 
measure the software encoder because at servo-thread speeds, several A 
pulses could go by between servo-thread samples. So it looks as if I'll 
have to set hm2_5i25.0.counter-mode true, at least long enough to obtain 
these answers.

I intend to hook this new encoder to the former A & B input circuitry, 
replaceing the shop made opto/slot encoders signals, but to maintain 
some sanity, a new encoder scale factor must be determined in order for 
the position output to reflect not the motor position, but the spindle, 
which will continue to get the old opto/slot's index or Z. This scaled 
position and velocity will then be fed to motion, near & similar places.

Which I read as being reset to start a new cycle when Z goes true.

So, is hm2_5i25.encoder.0.position.out still valid if counter-mode is set 
true?

Then I might be able to use a comp to drive a mux2 as a sample-hold, 
holding the highest count by grabbing a new sample if its greater than 
the one currently stored in the mux2.

That highest count after the spindle has been idling along at less than 
100 rpms for 10 seconds or so then becomes the scale after a *4 for that 
gear.  It will require a manual gear change to detect the 2 gear 
ratio's. And those 2 results then get committed to the ini file as 
SPINDLE_L_SCALE and SPINDLE_H_SCALE and used in the hal file.

Then all this gingerbread gets commented out.

Are there any gotcha's in scaling the values fed to motion as long as no 
synchronized moves are in progress at the time?

Cheers, Gene Heskett

What's the model of Cadillac? If it's rear wheel drive the gears are readily 
available from places like bowtieoverdrives.com
 
Advance Auto Parts shows speedo drive and driven gears for front drive GM cars.
Would be an interesting project to try, but the part should be available off 
the shelf.

 Greetings all;

A friend of the next door neighbors kid brother collared me at the 
grocery store today.  Seems he has acquired an 88 caddy that has spent 
the last 30 years parked in a garage, collecting zero miles.

But it has just broken some teeth off the speedometer gear in the 
transmission, and without that data the transmission is acting berserk 
and has rendered a showroom caddy un-driveable.

And he wants me to see if I can restore this broken, probably plastic or 
phenolic gear.

I have a hunch that as soon as I get this encoder working, then I had 
better get to work on my 4" rotary table as I'll need it to cut fresh 
teeth in the replacement plastic, or maybe even brass.

Caddy has been queried about it, but the last of those service parts was 
sold out in 2008 according to their reply.  So its make a new one, or 
else junk the caddy.

If I elect to do brass, that will probably need a specially ground 
tapered mill or a single tooth flycutter. Does anyone know where one  
might obtain a drawing for such a tool?  Or should I jut try to 
duplicate something that fits the remaining teeth on this one when it 
arrives?

Thanks guys.

Almost certainly a gear like this in not a simple spur gear.   Likely
a hypoid gear. The only way you are going to be able to make  spiral
bevel cut gear at home is either with a CNC mill or 3D printer   I
would try printing with nylon.

The quick way to model the gear is to go to McMaster Carr or one of
the other big suppliers and download the CAD file.  They seem to have
CAD files for every gear they sell.  Then modify the file and send the
resulting G-code to a machine, either a mill or printer.

I suppose there must have been people years ago who could cut a spiral
bevel gear by hand by turning cranks?  I know it is not hard to make
spur gears and worms and worm wheels by hand but bevels?

And YES the junk year would have these.  It just a GM transmission.
likely can still by the parts new.

Chuckle. Thats Good Stuff Peter, it will still be doing well long after 
we are gone I suspect. Leave notes for the missus so she doesn't give it 
away. Said by someone who isn't doing that, because her copd will finish 
her within the year.

Thanks Andy, msg marked, but first I have to get this person to ID the 
transmission. I didn't ask if he got the owners manual, which should 
list that stuff. I can do that when the piece arrives.

[Todd Zuercher]

I would have thought that one should be relatively easy to find at a local 
junkyard.  Depending on the model I would be surprised if it even had a cable 
and not just a pulse generator connected directly to the gear.  Most GM cars 
switched from cables a few years before that.

Ya mean there isn't a dead '88 Caddy in a junk yard near by. I assume 
the gear is in the rear of the transmission.
That is the first place I would look.

I'm a little closer to that, its mounted on and spinning with the motor 
a/o 30 minutes ago. But not hooked up yet, I want to power it and look 
at its output on the scope, it turns out that it has differential 
outputs and I need to check the swing of one line because thats all the 
inputs a 5i25 encoder has, expecting to see cmos rail to rail on 5 
volts. Or ttl at least.

And all that up and down on a short ladder has about finished my legs, so 
the testing and hookup will be tomorrow.

Thanks Dave.

Gene,
I assume that you have the gear which the one in question is to mesh 
with. Knowing the number of teeth desired (11), you should be able to 
find out or calculate the gear's properties, get a brass (or plastic) 
blank and produce the item on a mill (if you have a dividing head). Will 
be faster than guessing about old factory cooperations, looking around 
in catalogues or digging in junk yards. This way, I made the complete 
set of missing gears for my small precision mill on this very mill 
itself. I used slabs cut from hydraulic piston rods, manganese steel.

Yeah, but the junk yards long ago turned in the "gas guzzlers" and 
crushed them. Locally the chances of finding something pre 90 are pretty 
slim unless you buy it from grandpa Elijia's widow.

4wd Pickups are another class, lots of old pickups about, in various 
states of terminal iron oxide.

Knowing the caddy model would help but it looks as if Cadillac used Chevy
or Old's transmissions during those years. The transmission insert with
gear and generator should be easy to find.

Ya mean there isn't a dead '88 Caddy in a junk yard near by. I assume 
the gear is in the rear of the transmission.

That is the first place I would look.

Caddy has been queried about it, but the last of those service parts
was sold out in 2008 according to their reply.  So its make a new
one, or else junk the caddy.

If I elect to do brass, that will probably need a specially ground

might obtain a drawing for such a tool?  Or should I jut try to
duplicate something that fits the remaining teeth on this one when
it arrives?

Thanks guys.

I think thats the gear on the output shaft, and we probably need the gear 
that mates with it to drive the cable.

Thanks Andy.

[Emc-users] oddball job

[Gene Heskett]

Greetings all;

A friend of the next door neighbors kid brother collared me at the 
grocery store today.  Seems he has acquired an 88 caddy that has spent 
the last 30 years parked in a garage, collecting zero miles.

But it has just broken some teeth off the speedometer gear in the 
transmission, and without that data the transmission is acting berserk 
and has rendered a showroom caddy un-driveable.

And he wants me to see if I can restore this broken, probably plastic or 
phenolic gear.

I have a hunch that as soon as I get this encoder working, then I had 
better get to work on my 4" rotary table as I'll need it to cut fresh 
teeth in the replacement plastic, or maybe even brass.

Caddy has been queried about it, but the last of those service parts was 
sold out in 2008 according to their reply.  So its make a new one, or 
else junk the caddy.

If I elect to do brass, that will probably need a specially ground 
tapered mill or a single tooth flycutter. Does anyone know where one  
might obtain a drawing for such a tool?  Or should I jut try to 
duplicate something that fits the remaining teeth on this one when it 
arrives?

Thanks guys.

Cheers, Gene Heskett
