I once saw a mechanic in a so-cal tranny shop, using a monster 1/2" 
drive, trying to remove the u-joint yoke retainer nut from the rear of a 
middle 50's series Buick Dynaflow he had on the bench. A good 5 minutes 
of hammering on it without budging it.  He had also tried an 18" breaker 
bar.  Guy on the next bench picks up his butterfly 3/8, puts a good 
solid 1/2" adapter on it, walks over and grabs the socket off the 
monster, and says lemme show you how I do it. Making sure the socket was 
well seated, he rocks the butterfly to the left & fishes the nut out of 
the socket about 1 second later.  Time to send that 1/2" back for a 
rebuild.

That is cheap, but you still need to put a collet in each one.
A DIY TTS compatible tool holder blank, drilled & reamed, with the tool
held by a grubscrew would probably do for woodworking, e.g. :

https://www.youtube.com/watch?v=_2w8cYXt5_o

I'd make 'em on the lathe, rather than futz on a small wobbly mill, as
he does. But he says they're costing him $5 a piece, ready to go.

Dunno how good that kind of holder is for precision work. How much
eccentricity would the grubscrew introduce on a tight fit?

I'd also be tempted to use a slot drill or end mill for approaching the
final size, to leave a flat lip at the bottom of the hole, for the tool
to butt up against.

I do Andy, but the only 2.7.1 install in these here parts is the axis.sim 
on this machine.  The other 3 machine movers are all a 2.80-pre, and it 
appears to be working as I just went thru the g0704, adjusting the 
backlash comp until I got as exactly as close to a 5 thou jog in 
alternate directions as I could get, then played with scale's until 1" 
was 1" on a well aligned dial.

I don't have measuring tools to get any closer than that. the .ini file 
backlash entries are all above 2 thou even with these cheap Chinese ball 
screws.

Re: [Emc-users] Fwd: backlash compensation

[Jeff Epler]

For the following testing, I used the 2.7 branch at ref
v2.7.1-26-g21ae480 (26 commits past the most recent release, 2.7.1)

I tested backlash compensation by modifying configs/sim/axis/axis.ini to
add backlash to the X axis:

[AXIS_0]
...
-BACKLASH = 0.000
+BACKLASH = 0.100

I started with that configuration, homed all axes, and went into MDI
mode.

I approached X0 first from the positive direction, and then used halcmd
to look at the relationship between the joint command and the motor
command:
[MDI in axis]
g0 x1
g0 x0

[in a terminal window]
$ halcmd show pin axis.0.motor-pos-cmd axis.0.joint-pos-cmd
Component Pins:
Owner   Type  Dir Value  Name
23  float OUT 0  axis.0.joint-pos-cmd
23  float OUT   0.93955  axis.0.motor-pos-cmd ==> Xpos

And then I approached from the negative direction:
[MDI in axis]
g0 x-1
g0 x0

[in a terminal window]
jepler@babs:~$ halcmd show pin axis.0.motor-pos-cmd axis.0.joint-pos-cmd
Component Pins:
Owner   Type  Dir Value  Name
23  float OUT 0  axis.0.joint-pos-cmd
23  float OUT   1.03955  axis.0.motor-pos-cmd ==> Xpos

In this case, I see that the motor positions differ by .1 inch depending
on the direction of approach.  So the result of my testing is that
backlash compensation seems to operate as expected in at least one
situation.

I got similar results when using incremental and continuous jogs -- the
difference between joint-pos-cmd and motor-pos-cmd was either 1.03955 or
0.93955 depending on the direction of the last motion.

(The specific values 1.03955 and 0.93955 depend on the details of how
the machine was homed and would differ from run to run at least on a
real machine)

And now idle speculation as to why backlash compensation might be seen
not to operate at all for some users: I believe backlash compensation is
not activated until all axes are homed. So if you are using a
configuration that permits MDI & AUTO mode without homing, you might see
this happen (but this is just a memory of how linuxcnc used to work at
some time in the past and may not be accurate information for 2.7)

Re: [Emc-users] Fwd: backlash compensation

Thanks Jeff.  I was using a dial indicator and moving back and forth before and 
after setting "BACKLASH = 0.0005" and found no difference.  I think I was homed 
but will verify next time I am at the machine and will also try your method to 
see what the hal pins believe.  Is the "+" and "-" optional?

Re: [Emc-users] Fwd: backlash compensation

[Tom Easterday]

I entered a value in my ini file assuming that when I moved back and forth the 
movements would be compensated by the value in the ini file.  But at least for 
jogging and issuing G1 movements in MDI, nothing changes - that is the backlash 
is still present.   I haven't ever used it before so I was guessing that this 
is how it was supposed to work so I don't know if my expectations are wrong or 
it is broken (at least in 2.7.1)?

Re: [Emc-users] Carousel Component

[rick]

Hey guys,  

I will have to double check on Monday, but I am going to have to say that it is 
not installed, but just a folder in my home directory. 

As for the component in general, I went ahead with some test and tune, looks 
awesome for sure. Only question I have though, in regards to the homing 
sequence, if the Carousel is not homed, and I set "enable" true, it should stop 
rotating when it sees the sense.0 pin "home position" go true, then report back 
out on the carousel.0.current-position as being pocket 1 correct? And this 
should be done with out telling it go to pocket 1 on the 
carousel.0.pocket-number input during the homing routine?  

Reason I ask, the only way I could get it to stop on the home position switch " 
pocket 1" during homing, was to use an assignment block in my ladder logic that 
I set to "1", at the same time I start the carousel homing sequence. Then it 
works as intended I believe.

There is scope for confusion here. linuxcnc-dev is a package that can
be downloaded from the package manager, either through the synaptic
gui or with
sudo apt-get install linuxcnc-dev

However, if you download the LinuxCNC source code, that generally ends
up on a folder also called linuxcnc-dev. But you can have either one
without the other.

On the 12 speed drill/mill I used to have, I used a "pickle fork" 
(automotive ball joint separator) to pop its MT2 toolholders out.

Having a drill press based head, it only had weedy sub-1/4" metric 
drawbar which was useless for driving the tapers out.

Making a fork with a wider slot for MT3 wouldn't be difficult. I bought 
mine at Harbor Freight for cheap $.

Re: [Emc-users] tool changers

[Peter Blodow]

Gentlemen,
my old little Steinel vertical mill, older than the Black Forest, has a 
MT3 (MK3 in German). Above this, the bore is drilled hollow 14 mm all 
the way through to the top of the machine. The collet holder (1 - 20mm) 
that came with it has M12 inside threads at the end and can be fastened 
by a 12 mm pulling bar, if necessary. I made all my other tool holders 
the same way.

An almost new large milling head that was given to me because it was 
said to rattle and to be instable. I decided that a MT3 holder was way 
too thin and too long for such a big head. So I figured out the outside 
taper angle at the lower end of the quill, some 60 mm thick, and turned 
a plate shaped holder fitting over the outside of the quill. It will be 
pulled up by a long bar just the same. You should see the old maid 
making chips with a big 8 blade cutting head in alu at high speed! 
Furthermore, this construction is rather short and gives me more height 
between the tool and the table. Consider unconventional methods, too.

Peter

Every Morse taper milling machine I have seen has a draw bar or a keeper

My HBM has a #5 MT and will loose the tool holder if I do not put in the 
keeper.

I have visions of it being so.

  Something that would drop a wrench/socket on the drawbar, and a 1/4 
second blast at full power of the motor.  Let it turn half a turn before 
the socket hits a stop hard enough to break it loose. then a 100 rpm 
command till it fell out, insert the next tool, command 100 revs in the 
other direction to draw it back in, and let it hit the stop going the 
other way. Even at 100 rpm, I can't hold it so I'd think that would be 
tight enough.

  I can imagine doing all that in a classic ladder script, but shifting 
the head to low gear will need a major redesign of that gear shift 
mechanism.  Something that can push-pull a lever while the  motor is 
commanded to 5 or 10 rpm's.  Slow & possibly spring loaded so the gears 
can mesh when the teeth are aligned without damaging them.  If the 
artificially stiff crap is removed, (something I haven't investigated 
yet but suspect is all in that huge knob it almost takes both hands to 
turn) a windshield wiper motor ought to be able to handle that, with 
suitable mods to its parking switches. AFAIK, all its doing is sliding a 
gear up and down a splined shaft.  From the noise, I'd have to say the 
gears are straight spur gears, with little or no end thrust to contain.

Jon's (Pico Systems) pwm servo controller can make that motor do anything 
I want it to do, including a fwd to reverse (or back fwd) in about 1 
second flat while running at 2500 revs.  Use some of that power to run 
the spindle with the drawbar bolt locked.  I don't think it needs more 
than 1/2 turn after breaking it loose unless the R8 is sticky.  So far, 
that has been a very minor problem. My fingers on the top of the bolt 
once its loose have always been sufficient to eject it from that 
condition.

> A c-shaped plate that could pivot across to catch the larger diameter
> might suffice.

I have a vision of a plate full of C slots, say perhaps 4 or 5, whatever 
it would take, to be swung as an assembly, to receive the falling tool, 
raise the head to clear the tops of the TTS studs, then turn the plate 
to bring the next tool under the spindle, set the spindle down onto it, 
and run the spindle the other direction to pull it in and lock it.  
Raise the head far enough to clear, swing the tool carrying wheel back 
out of the way, and go back to work with the next tool.  Can you say an 
ATC for a G0704?

That would take some tool table editing on a per job basis, to tell LCNC 
which pocket tool "14" is in, but that doesn't appear to be a major 
hassle.

What would be considered, strictly on any one given jobs basis, to be the 
minimum number of available slots?  4? 6? This particular job only needs 
3, and one of them is also a different file to load.

  Chuckle. :)  Yeah, its probably still in the genome.  Lots of "trash" 
DNA in there yet.  We call a miss-fire, or a potential enhancement, a 
birth defect now-a-days.

  I have seen babies with 6 fingers and toes, all perfectly formed and 
100% working, but they take them off!

  I have wondered to myself if thats the next step in the evolution of  
this tool designing and using critter that is us. ;-)  Enhancing our 
ability to use the tools we can build?  Sadly, thats not "PC" to allow 
that.  I won't say flat out that we are playing God, but 
that 'corrective surgery' sure fits what I've observed.  How dare we 
evolve?

Yes, for axial loading such as drilling. There is no doubt that they
work perfectly for this in millions of lathe tailstocks and drill
presses.

But I think asking one to work for milling (unless you always make
sure you do a nice hard plunge cut at the beginning) sounds like one
of those things that will be perfectly OK most of the time, but then
won't be.

[Emc-users] Carousel Component

[rick]

Good Morning Guys,

Have a question for Andy Pugh,

Finally got to the point of integrating the carousel component into my
machine, and was wondering, how do I connect a signal name to the
parameter pins in the component, so I can use the home related pins in
my ladder logic?

I have the rest of it programmed, I just need to see the home state of
the component, and I was going to use the compare function in
classicladder.

Thanks

Rick

You can't. I am afraid I didn't consider that anyone would want to.

You will need to edit the carousel.comp defnition file to make the
home state into a pin rather than a parameter.

ie change
param r  signed   state = 0 "Current component state";

to
pin out signed   state = 0 "Current component state";

Then sudo halcompile --install carousel.comp  to install the new version.

(Why do we have both pins and parameters? Pins use up shared memory,
parameters use the much less limited ordinary memory).

That works, but that isn't the image I have wandering around in the back 
of my mind.  There's a small gap between the top of the nut, and the 
larger OD of the TTS adapter, that I have a vision of engaging with the 
rotary plate holding several tools by that means. With a counterbore in 
the top face of the plate to keep them from jiggling out as the whole 
assembly pivots in and out of position.

Unforch, I haven't mastered a cad proggy well enough to draw it.

Sketchup, someday...

Yeah, that is the default for China.  And keep in mind, nothing is 
guaranteed.  Maybe I got lucky.  Many of these China sellers
(including this one, for smaller items) use a very inexpensive
"e-packet" shipping process that goes thru China Post and then
the US Postal Service.  That does take a while.  It might be that
the 10-pack of toolholders is too big for e-packet.

A google later yep, e-packet is limited to 4.4 lbs.
http://www.ecommercebytes.com/cab/abn/y11/m08/i31/s02
That is how so many china sellers can offer free shipping on 
small items

Do you actually need (or want) ten?

If you get two or three people who want two or three holders each
this might be an opportunity for someone to buy the 10-pack and
split it up.

If you only need two or three for this project I could probably ship
you a couple of mine.  I don't need all 10 right now.  But I will want
them eventually, so it would be a loan, not a sale.

Re: [Emc-users] Carousel Component

[rick]

Thank You Mark,

I found the file with locate, then saw your email,

I changed the lines in the comp file, but am running into a problem on
the compile, I am trying 

"greenmill@greenmill:~/linuxcnc-dev$ sudo halcompile --install
carousel.comp
[sudo] password for greenmill: 
sudo: halcompile: command not found
greenmill@greenmill:~/linuxcnc-dev$"

And you can see the result, any thoughts?

The fleabay adv doesn't say a thing about that fast a delivery, just 
vague promises of sometime in the 2nd or 3rd week of November.  I'll get 
the collets from LMS on super Tuesday if history is any indicator.  Next 
week for these would sure be the icing on the cake. And worth the $60 
bucks. ;-)

You can create comps and use halcompile on any LinuxCNC system. You
might need the LinuxCNC-dev package from the package manager, but you
don't need git / sourcecode etc.

Re: [Emc-users] Optimum packing problem

[John Kasunich]

Glib answer:  It doesn't matter.  If you have N storage spots for a given size
collet, it is inevitable that you will eventually have N+1 collets of that size.

Serious answer:  I have a scalable design for collet boxes, and I make a
box for each size.  The ER20 collets live near the machine that uses them,
the 5C collets live near their machine, and so on.  I wouldn't mix sizes in
one box unless I was very short on storage space.

Probably means it's not on your path.  You can confirm:

Should show if in your path or not.

If not, use the find command again.

Then, either use the full path, or cd to the directory it's in and
preface the command with a dot slash:

The "profit in the shipping" thing is just a game.  Add up the total cost,
divide by the number of tool-holders, and they are $16 each.  That's either
a good price or it isn't.

In the case of this particular seller, you get your $60 worth.  I bought the
exact same article from the same seller.  He shipped them DHL and 
they arrived from across the ocean in 3 days.  Complete with a phone
call the day before they arrived to tell me that a signature was required 
and how I could manage that if I wasn't going to be home.  Impressive
service, much better than the usual from UPS or FedEx.

I wonder what the optimum packing is for a mixture of ER32, ER20, ER16

A square array of ER32 with interstitial ER16, then a separate array

Actually pins and parameters both use shared memory for their metadata
(which is much bigger than the actual pin data, 50-60 bytes vs 4-8 bytes).

We have both because I made a bad decision a long time ago.  I used a
hardware analogy when designing HAL.  Pins are like the inputs and 
outputs of a servo amp.  Parameters are like the adjustment pots on that
amp (gain, etc).  I made a false distinction when I decided that some things
would need to be interconnected and other things wouldn't.  People always
find new ways to do things, and they want to interconnect stuff that I thought
they wouldn't interconnect.  In hindsight, everything should have been a pin.

I can see that, it was just intended as a quick and dirty way to catch
the holder for manual changes until you grow more limbs.

A loop of string with a hook might be quick and easy. It just needs to
stop the holder dropping all the way out.

Ten of the TTS adapters?  Thats a bit like Orville and his popcorn, the 
bowl is forever one handfull less than what you wanted  when its been 
emptied. :)

That will give me 4 each of 1/8", 1/4" and 3/8".  No clue what I'll ever 
do with 4 each .375" collets though, router bits jump from 1/4" to 1/2".  
If I ever need the 1/2", I've an R-8 for that.

Just for S & G, I took that big fugly half a pound of satin finished 
metal gear shift knob off, squirreled the detent parts into a spare 
collet box & put the knob back on.  Putting it in low range, very easily 
done now, and with the drawbar bolt held by its wrench, and an estimated 
15 degree run till the wrench hit the motor housing and stopped, a 20 
rpm fwd command was more than enough to drop the TTS tool into my hand.  
Setting the spindle into reverse & holding the TTS adapter in, it 
trapped my hand between the wrench and the motor houseing, and is 
probably tighter now than I have ever put the wrench to it by hand.  I 
wasn't injured, but did have to hit the stop button to get my hand, and 
the wrench free again.

The question of "does the spindle motor have the huevos to do it?, seems 
to be  answered in the affirmative, rather loudly.

So next is to make an about 5 port wheel & figure out a ratcheting 
mechanism to turn it, probably involving a 2nd windshield wiper motor.

Home will be easy, rig the home switch to bridge the wipers motors 
parking switch with a small enough R to keep it going until the home 
switch opens.  Call that Pocket 0.  Then to find the pocket needed, bang 
that resistor across the home switch with another relay, and count the 
current pulses as its park switch goes by, stopping it when the correct 
number of counts has arrived.

  Followed by a fairly long wheelbased vertical axle to swing it into, 
and back out of position.  Possibly also run by a wiper motor.

And the code to bang the motor, and shift the gears.  Sounds doable to 
me. ;-)

But, I could well have to pester you kind folks about interfacing 
questions too, since this is dirt I've not played in before...

Thanks for the offer John, but sure as heck, I'd forget where I got them 
by the time you'd want them back.  At my age, short term memory is, to 
be kind, poor. So I'd druther not go down that path if I can help it.  
In the meantime, I'll survive.  But I am NOT turning on a microphone in 
the shop either. :)  Some of what has been said out there is best not 
recorded.

I have a lathe, a mill and a mill/lathe, Mig and TIG welders, a

I _am_ short of storage space.

Do you have the linuxcnc-dev package installed?

halcompile used to be called comp, but I think that your version is
new enough for it to be halcompile.

I am slightly surprised that you have the carousel.comp file,
actually. And that you appear to have a linuxcnc-dev directory.

It works a lot better for straight-flute cutters, like 
horizontal mill arbors and such.  Yes, the spiral flute

Re: [Emc-users] Carousel Component

[Mark Wendt]

You have to use locate or find to find out where "halcompile" is.  Or
you may have to install the dev package if it's not on your machine.

There is scope for confusion here. linuxcnc-dev is a package that can
be downloaded from the package manager, either through the synaptic
gui or with
sudo apt-get install linuxcnc-dev

However, if you download the LinuxCNC source code, that generally ends
up on a folder also called linuxcnc-dev. But you can have either one
without the other.

Does it need to be automatic? The drawbar isn't.

A c-shaped plate that could pivot across to catch the larger diameter
might suffice. Something like
https://picasaweb.google.com/108164504656404380542/October302015#6211393457778332834

Though something like that could be persuaded to operate
aitomatically, maybe through a Bowden cable operated by a cam on the
side of the column, so that it pops in at the top of travel.

It seems to me that we probably still have the DNA for a prehensile
tail, it has probably been turned off rather than deleted. That would
be useful.
