This one is a 745, 4Gb of ram & a new 2T sata drive since there is not a 
PATA interface on these mobo's.

Done, install in progress but synaptic is fussing about the keys yet.

I'll let that finish, get the keys and install them as below, then 
refresh & start getting rid of xfce, starting with lightdm.

Not a fan of aptitude, its not as intuitive as synaptic.  But it also 
doesn't need a wrapper to let it use what little gfx it uses.  As a #1 
user, you have to run synaptic-pkexec, which then asks for your pw and 
works on your x profile.  Sudo synaptic can't open a screen on your 
session of x.  Both seem to have the full power of apt-get at hand 
though.

Thanks Nik.  What sort of a machine are you driving?  The one in question 
is a G0704 Grizzly mill,  fleabay ball screw kit & fleabay motor/psu's 
kit. 5i25 interface.  Needs more voltage on the Z as it can only do 
about 42 IPM.  Nema 34 motor only on Z, triple stack nema 23's on x/y, 
can do 70 ipm.

Configured for an A rotary table, but the table and motor kit hasn't been 
obtained yet.

I have a smaller 4" table (no center bore either) with a motor on it for 
the toy mill that I could, with a bit of tom-foolery, rig if I need one 
desperately. But its such a backlash ridden POS that I've cut a groove 
in the mating face, drawn the bolt up fairly tight, and I hit that 
groove with about 90 psi for air lube when I want to move it at any 
speed at all.  Even thats not enough to really control the backlash if 
the cut is more than 2 thou per pass.  I made some beautiful sprockets 
for #25 chain, teeth about 4 thou too wide to enter the chain, thanks to 
that backlash.  Had to file then narrower. But it was for a bandsaw 
fence drive, not a Cathedral.  It works, for sharpening tools etc. :)

[Emc-users] Tool changer finally working on our mill project

[Rick Lair]

Here it is, after putting all the pieces together, and working the bugs 
out, I finally got the tool change working using Andy Pugh's carousel 
component to control the tool carousel, and a pretty healthy chunk of 
ladder logic to control everything else. All using Linuxcnc 2.7.

Thanks for the help guys,,,

It looks perfect for any machine with a gear on the spindle. (I had to
read a long way into the datasheet before I was sure it didn't need a
magnetic target).
For many applications you would also need a separate index.

Did that, had to nuke xfce and lightdm to keep them from overriding 
things, but now nothing lcnc related will run, familiar problem I've 
forgotten how to fix, "BACKGROUND color not defined".  And when I fix 
that FOREGROUND color will be a duplicate show stopper.

The rest of it seems raring to go.  But I can't stay in here more than 
another 10 minutes as I've slathered on coat of tung oil on a chest lid 
I have to go wipe dry.  Then I hit Lowes in Buchannon and get me a 
couple more rolls of toolbox drawer liner to pad and non-skid the top of 
my work table, and some sort of a teflon tape to cover the skid plates 
on my biscuit jointer, its scratching up the wood and it doesn't show 
until its wet with tung oil.  I'm using it as a router to plow grooves 
for the  book ends of the lids, which need a groove for location strips, 
locking the wide top panels to the heavier end boards to stop, or try 
to, the warping of the tops, which are 2 widths of 1x12" 41.25" long 
biscuit joined to make one board.  And this kiln dried stuff is warping 
like crazy.  It was sunk in a river in Honduras for about 100 years 
until fished out and and dried because there is no new Mahogany being 
harvested, tropical rain forest rules & regs we are told.

And I'd better go get to wipeing off the surplus, Minwax says wipe 
completely dry.

Re: [Emc-users] Tool changer finally working on our mill project

[John Dammeyer]

Hi,
Any reason why you won't push the tool holder outwards once it clears the
carousel so that when it arrives under the spindle it's already fully
extended?  Would save time on tool changes.
Very nice though.

Re: [Emc-users] Would this new item be of any use?

[John Dammeyer]

I too got that advertisement.  If your spindle has a suitably fine gear on
it I think it would work fine.  You'd still need to add a second sensor for
an index position in order to either thread or position the spindle for a
toolchanger.

Hi Gene!

LOL ... I think the rinity mailinglist has an archive :-)

Place this in your .bashrc if you run linuxcnc from commandline (all in one 
line):

alias linuxcnc="xrdb -all -query|sed -e 's#[A-Z_]*BACKGROUND# gray90#' -e 
's#[A-Z_]*FOREGROUND# Black#'  -e 's#[A-Z_]*HIGHLIGHT# White#' -e 
's#[A-Z_]*LOWLIGHT# Black#'|xrdb -merge; linuxcnc"

or place this fragment in .xinitrc (all in one line) or any script that gets 
executed when you log into your X session:

xrdb -all -query|sed -e 's#[A-Z_]*BACKGROUND# gray90#' -e 's#[A-Z_]*FOREGROUND# 
Black#'  -e 's#[A-Z_]*HIGHLIGHT# White#' -e 's#[A-Z_]*LOWLIGHT# Black#'|xrdb

When I was writing the ladder logic I followed the original sequence of events, 
but this does make sense, guess I've got some tweaking to do.

Re: [Emc-users] Tool changer finally working on our mill project

[Dave Cole]

If you rotate it with it extended it will have a lot more inertia, tend 
to throw the tool, and be harder on the rotator.

If it was rotated with the tool retracted originally, there is likely a 
good reason why they did that.

Re: [Emc-users] Would this new item be of any use?

[Bruce Layne]

The resolution is determined by the number of teeth on the gear that is 
being sensed by the two Hall effect sensors in that integrated Honeywell 
sensor.  For example, if you had a 100 tooth gear, you'd have 400 
quadrature state changes per revolution.  A spindle speed sensor doesn't 
really need much resolution.

As others have stated, there is no index pulse, so you'd need to add 
that for a spindle encoder if you wanted rigid tapping, but if you only 
wanted a spindle speed indicator, this should do the trick.

The sensor looks very durable, mechanically.  Two discrete Hall effect 
sensors that we'd bend around until they were in a quadrature generating 
alignment would be cheaper, but not nearly as durable. It also looks 
like Honeywell put enough electronics in there to provide some much 
better noise immunity than discrete Hall effect sensors would probably have.

Certainly a decent price, but zero mention of its resolution?  We need 
specs, and they aren't there.  The datasheet also will not dl for 
iceweasel.  Good price, but color me un-impressed until I see some real 
specs.

I have a first-generation dual Xeon server as my lathe controller. I
seem to recall that it was about 25k latency when I first got it, but
I don't know what it does now with the newer kernels.

I know it needed the SMI tweak. But with that it never flags the
real-time delay message, so I assume it's OK.

Re: [Emc-users] Tool changer finally working on our mill project

[Stephen Dubovsky]

You may need to have it retracted to clear another tool in an adjacent
pocket in the turret.  What if you put a large diameter tool, like a face
mill, beside another?

If you could build a constant volume/displacement hydraulic system, with 
no accumulator or other buffer that takes fluid out of the main circuit, 
you could have a linear relationship between whatever moves the oil and 
the cylinder that gets moved.

If you had a cylinder with the same volume and stroke, and same rod 
diameter, it should be possible to connect the end with the rod of each 
cylinder to the other end, without the rod to keep the two volumes the 
same. Push or pull on the external cylinder and the one on the machine 
should move the same amount.

Connecting rod end to rod end and the rodless ends together wouldn't 
work due to volume changes. The cylinder pair would be locked up.

How to drive it? Mount screws parallel to the driving cylinders and 
arrange them all vertically on a frame.

One use for such a setup would be retrofitting old hydraulic CNC and 
tracer mills to modern CNC systems for faster speed. Those old 
Bridgeport hydraulic tracers could rip along at up to 13" a minute. Wheee.

Looks like they would be a nightmare to keep running with all the valves 
and switches and pipes and hoses going to and from the tracer, the 
cylinders and the pump and reservoir.

I had to use this version.  Adding the below to my ~/.xinitrc did 
nothing, and on the third reboot to check, since a logout and back in 
wasn't working, network-mangler ate my lunch, zeroing out what I had 
setup 2 months ago.

So that got nuked, then rebuilt resolv.conf and interfaces from memory.  
I must be getting good at that, the first try worked.  But what was eth6 
before is now back to eth0.  I figured I'd have to generate new sshfs 
keys, but it all worked.

If there is a single piece of system software that will trigger my 
personal, no duplicates copy of a nearly 15 minute monolog of swearing 
in  several languages, network-manager is it.  I have never had it 
explained to me, why the hell it should tear down a perfectly working 
hostname based network.  Under a 10-04 LTS install, it wasn't 
removeable, so all you could do is a root session of chattr +i those 2 
files the instant they were written.  Somehow it didn't have the 
chutzpah to squawk when it found they were read only, the only thing I

Interesting.  An opto, reflective style, watching a mark go around would 
serve as an index I'd assume.  I did not pay enough attention if its 
size was even noted, but something like that, watching the bottom gear 
on the toys spindle might be just what the Dr. ordered.  The gear is at 
least a 50 toother, maybe a few more.

Re: [Emc-users] Tool changer finally working on our mill project

[John Dammeyer]

I guess that depends on how fast it rotates and how the tool is gripped.  It
also depends on whether the rotation is a DC motor with end stop switches or
a servo with position reporting.  No point in moving and decelerating to a
stop, telling the unit to extend and then accelerating back up to the
rotation speed.
If it is DC motor based a switch half way around would serve as the
extend/retract begin indication.  
On the way to the spindle the switch triggers the extend.  On the way from
the spindle the switch triggers the retract.
Only when ready to store the tool does it extend again as it does now.

I don't think it is actually either of us:

It just has my name (or Jeff's name) and Jack's email address.

Don't buy or accept a free server that doesn't have its drive trays. 
Every manufacturer uses different trays and usually changes the design 
with each new model line.

A freebie old server without trays can end up costing a couple hundred 
bucks.

It's lazy IT departments who can't be bothered to work a screwdriver for 
a couple of minutes that are to blame. No reason to keep the trays 
because they'll have no system they'll fit once the old servers are gone.

[Emc-users] Need a better wm/Gui for my machines

[Gene Heskett]

Good morning everybody;

I am running TDE on this box, and am quite happy with it.

The wm, I think its xfce, on the real machines, suffers from a utility 
for this, and a utility for that, that winds up having poor control of 
screen usage, tieing up two vertical spaces for all its buttons, none of 
which seem to register their presence with the wm so that LCNC is 
prevented from underlaying them, which when it occurs, screws things up 
because you must alt+ click on the lcnc window and drag its top bar out 
from under the wm's toys in order to gain access to the lcnc menu 
pulldowns hidden under the wm's bs.

I have a congenital distate for gnome with its difficult, never does what 
you ask, configuration interface.

So on your machines with limited horsepower like the atoms, what wm/gui 
family are you folks using?

While "taking it easy" after some spinal block shots in my lower back 
yesterday, I am considering installing TDE R14.0.02 on the Dell 
Dimension 745 that runs the new mill, but I have doubts the atom boards 
can handle that on the toy mill before I install a 5i25 on it, which is 
still waiting to be installed as all that is definitely on a shelf, 
above my comfortable reach, at least till I find out what my back can be 
trusted to do for the next few days/weeks.

And at $140 bucks for one of those Dell Dimension 745's w/o a drive in 
it, its very tempting to buy 2 more, that dealer has plenty of them.  
Dead stable machines. Without a UPS on it, its been up 29 days now.

Thats (the toy mills conversion for more speed and power) a three-pronged 
rebuild as I will remove the 28 volt supply from the controller/driver 
box and substitute a 42 volt bank of switchers for it. 5 ea, 3.3 amp  
modules set at 42 volts, with .47 ohm current sharing R's between them 
and the common 42 volt line.  That also means I'll have to round up a 5 
volt supply to run the BOB and other logic with.  Basically thats first, 
make it run again, then reconfigure for the 5i25.

A spindle encoder would be nice, but thats awaiting a bigger motor, the 
400 watter I took out of the lathe, and a whole new drive. With a 
lowered mount by removing the gearhead box & starting from the sled 
casting, a sliding mount for two step timing pulley drive, likely 
fabricated on site.  What v belt or o-ring belt drives I've seen look 
like slip-o-matics to me.  And slippage means stalls and broken tooling.  
Not good.

Too many plans, not enough me left.  Darnit.  But I can fiddle with 
software from a chair.  And the existing gui isn't exactly what I want. 
Particularly on the GO704.  Thats an underlay nuisance I'd like to get 
rid of. Presently I have moved both "bars" to the bottom of the screen, 
but that wastes screen space too.

Also, I am using an old (new in 2007 as the hidef was coming online 
slowly) samsung 22" hidef tv (ccfl backlight) with a bad tuner as its 
monitor, and dpms isn't working.  Is that endemic to that category of 
monitors?  Only fixable by throwing money at it?  FWIW, I have not tried 
to use "xset dpms time time time" to set the times, its possible only 
the screen blanker time is set by default.  Since I can't do that from 
here over the network, I'll have to both be at that machine AND remember 
it. At my years, thats a trick. :(

I can't for obvious reasons, open the 0.0 display from here.

Cheers, Gene Heskett

Hi Gene!

As you might suspect, I'm running TDE on my mill, too :-)

Re: [Emc-users] Intel Xeon, Real time performance

25k? Should it be 25µ?

I tried POS terminals, they have touch screen but delay is not good.

The "old" one was a Dell Optiplex 755 (I think) from 2008 with 1G RAM and a 4GB 
CF-Card. The "new" one is a D945GCLF2 with 1G RAM and again a 4GB CF Card.

I added Slavecs repository to /etc/apt/sources:

deb http://mirror.xcer.cz/trinity-sb wheezy deps-r14 main-r14

then install Slavecs keys and TDE:

# apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-key 
A04BE668
# aptitude install tde-trinity

And then get rid of the stuff you don't like (xfce ...) :-)

I apparently need the apt-key get incantation for your site Nik.  Thanks.

Re: [Emc-users] Tool changer finally working on our mill project

[rick]

Proportionally controlled hydraulic motor, with hard stops and limit switches 
at each stopping point of its travels. It takes about 2.5 seconds to make the 
180 degree rotation. That is about as fast as I can get it to go, without 
having the tool shaking/rocking too badly when it stops to be exchanged or put 
away.

I guess that depends on how fast it rotates and how the tool is gripped.  It
also depends on whether the rotation is a DC motor with end stop switches or
a servo with position reporting.  No point in moving and decelerating to a
stop, telling the unit to extend and then accelerating back up to the
rotation speed.
If it is DC motor based a switch half way around would serve as the
extend/retract begin indication.  
On the way to the spindle the switch triggers the extend.  On the way from
the spindle the switch triggers the retract.
Only when ready to store the tool does it extend again as it does now.
