Use small turn buckles to tighten the cables over the block on that one

rectangular 3/8" walled extrusion that is 145" long.

Under normal jogging commands the two servos control the ends of this gantry 
reasonably well, but while the axis is homing the thing shakes and wobbles 
terribly bad.  Also If I put a dial indicator in the center of the bridge and 
hit the bridge forward or backward it will flex and wobble enough to displace 
the dial indicator +/-0.03 and it takes nearly a dozen wobbles to dampen it.  
But on the ends the servo's only have a few thousandths of give.

I'm less concerned about the actual stiffness and more worried about dampening 
the wobble.

Is it possible to translate those files into G-Code?  I did the original

Re: [Emc-users] Semi OT: Variable speed DC drive for Fanuc brushed DC spindle drive

 Leonardo
Thank you for your reply.
If you get the Machdrives please let us know if they are easy to tune.The Tuna 
software looks easy to use and appears to be full featured but you can never 
tell till you use it.If you do order, order soon. International shipping takes 
several weeks.I asked if they wanted me to be a stocking US dealer. They said 
no.

I went with the 160 volt drives as that gives me some voltage head room to 
prevent shutdown on a voltage surge.

We just purchased a Mori Seiki SL3 lathe that's going to be
retrofitted with LCNC because it has no control.

The machine has a brushed DC spindle motor and from what they told me the
DC drive was not working (I would like to check this but I couldn't find
any info or manuals for this drive, the model number of the drive is
A20B-0008-0372/02). I would like to keep this motor because I like the idea
of having high torque at low speeds because I plan to use a milling and
hobbing attachment with this lathe.

I'm trying to find DC speed controllers of 15 kW or so, just to take a look
at what it's available but it seems difficult to find something that big.
Do you guys recommend any particular brand or source to find such a speed
controller?

Thanks as always.

Re: [Emc-users] linuxcnc openlung ventilators

[Dale Ertley via Emc-users]

  What is the chance that a BIPAP (twopressure system) machine could be used as 
a “first line” for a ventilator?  
A CPAP (single pressure system) may also work.
It might even work with an O2concentrator.

Pressures could be raised andlowered if necessary.
I don’t think it could be used with patientintubation.  
There are millions of them outthere.

Thoughts that come to mind:

Outback products are top drawer

This seems to be a 24 Volt battetry system, my cheapish solar charger 
has set battery parameters: flooded LA, Gel LA,  but also a user 
selection that can be set for whatever such as LiFePO4 or any other 
chemistry if the user knows what they want. I would assume the Outback 
has a similar feature but I haven't found it yet. I am collecting 
LiFePO4 Headway 38120 cells when good deals come along. AlarmHookUp 
seems to be a good source of batteries, but not totally risk free.

Re: [Emc-users] Going off-grid [Was: Thinking about going off-line eventually.

[Dale Ertley via Emc-users]

 This might be a nice way to go off grid. I have 2 HDT Balance of System (BOS) 
units with 5 solar panels. Engineer told me I could tie 2 together to get 220 v 
ac out. Outback GTFX2524, FLEXmax 60, and alot more in them. I will let them go 
for my cost. Got at gov auction. No batteries.

Direct thermal refrigeration may make sense.  Sun heats a 
water loop, drives off the ammonia, and then it is 
reabsorbed to cool the cold side.  You could do the same 
with lithium bromide, although that is a salt that could end 
up clogging things.

When confined to a building, it can cause MASSIVE 
explosions.  The fire marshalls just LOVE ammonia systems!

Re: [Emc-users] Lubrication

[Dale Ertley]

Hello
The actual service life of wind turbine gearboxes is often well below the 
desired 20 years. One of the prevalent failure modes in gearbox bearing 
raceways is white structure flaking (WSF) by the formation of butterflies and 
white etching cracks with associated microstructural change called white 
etching areas.

The term "servo motor" does not necessarily imply a positioning drive.

This is Siemens explanation since they make so many drives and motors 
for different uses:

https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/10045149?tree=CatalogTree

Notice that the 1PH8 motors are Simotics M main motors and they say they 
are for precise and smooth running of rotary axes.

The Simotics S is the true positioning servo motors that are put on CNC 
machines for position drives.

Years ago (early 90's)  when I was working for Siemens, I visited a 
company in or near Cleveland, OH that was making high end spindle drives 
and motors.
I forget the company's name.  But the company contacted Siemens since 
they wanted to use Siemens drives with their motors.  I think I was one 
of the first guys to visit the company from
Siemens.    At the time, the existing Siemens drives could not control 
their motors.  Their motors were a hybrid motor that could be act as an 
induction motor at high speeds yet could do very accurate positioning at 
low speeds with decent torque.  It was a near perfect motor for a 
machine tool spindle.  About a year later Siemens bought the company 
and acquired their patents and  dissolved the company.    I met the 
company owner and I think he was happy to sell out to Siemens.  I'm 
sure that he did very well in the sale.

Re: [Emc-users] Got my first signal out...

Ray,
We may want to put a short note in the docs to explain that the screen/monitor 
resolution may need to be changed to see the complete view of some of the 
pages. I have seen this problem 2 times with new users. Personally it set me 
back a few hours until I figured it out. The new users want to use the Step 
Wizard but can not see the bottom of the page (the control button). The Step 
Wizard seem to be the problem module. I have not come up with a good page(s) to 
place the note but I think it needs to go in there in larger bold text. Maybe 
show them the drop down menus of how to change the resolution. Lets reduce the 
frustration of the newbies. Martin is doing well with the stepper system. I can 
not wait to watch him do his full size servo Hurco mill. You my see him at EMC 
2010. You will see me there.
Thank you for your help

Having said that, a standard parallel port is fine for 3 axes + limit

CNC-WORKSHOP
NEWS
I’ve been asked by several folks about the 2009 CNC-Workshop. Unfortunately, 
there will be
no workshop this year.
I have had a serious medical problem starting early December and running 
through mid
January. Hit my head on a low beam about Dec 1 and felt pretty bad for a couple 
of weeks.
My right hand quit working and my doctor sent me to the local hospital for a CT 
scan. Ended
up with a helicopter ride to the critical care neurological unit in Peoria. 
Seems I had internal
bleeding inside my head putting pressure on the brain.
They drilled a hole for a drain tube but it didn’t fix the problem. A week 
later they cut a 50
cent sized hole and hosed things down inside. At least I think so, but I was 
asleep at the time.
They reassembled things with titanium screws (they tell me).
I have decided that it is time to close down Cardinal Engineering and retire. I 
am building a
large garage behind my house that will have room for a “hobby” machine shop. The
equipment will be sold and if any of you guys want to buy some of it, I’ll make 
you a really good
deal.
I believe the EMC contingent will have their meeting in Kansas. Contact Ray 
Henry for details.
An auction will be held for the remaining equipment not already sold, probably 
in early June
or July.
I’ve really enjoyed having the CNC-Workshop each year and would like to 
continue but my
doctors (and my wife) feel that it would be better at this time to eliminate 
the stress of holding
it in 2009.
If you have any interest in the equipment, CNC components, hardware, or 
attending the
auction, etc., get in touch with me by e-mail or phone.

Re: [Emc-users] Off topic-Electrical design help

[Dale Ertley]

Can't we run an AC servo in a + or - torque mode, based on a + or - control 
voltage applied to the servo drive? Clockwise rotation (torque force) for + and 
CCW for a - control voltage. The servo tries to maintain a commanded torque 
output. Forcing the motor shaft to rotate. I would think DC servo drives will 
do the same.

Is there a reason such as cost or space that an off-the-shelf drive for the
motor cannot be used?

Some of the new drives have the capabilities that you are looking for built in.
I was just hearing the other day about a Siemens drive that is even line power
regenerative-when the motor is being used for braking the energy is not
dissipated in a resistor bank, but is put back into the power line. So the
braking energy is actually powering the lights in the building (for example-you
could thing of it as running the air conditioning too).

The energy efficiency is not quite the point here, just that a drive may be
available for that motor that already has the drive/braking capability you need.

Unless you are wanting to work it out for the fun of doing it, which is
something I completely understand!

 it was true, the MHMD motor is only for the asian A4C series

 now isnt that intuitive? ;)

 anyway,
 you more than likely have the basis to use Yaskawa and SureServo ( 
 automation direct 'koyo ) also
   
The Panasonic encodes the 3 commutation signals with a UART, sending 
8-bit serial bytes at 1 Mbit/second.
So, that was quite easy to decipher and design a simple gizmo to convert 
back to the standard UVW commutation signals.
These motors have traditional ABZ position encoders.

On the proprietary Yaskawa motors made for their own drives, the encoder 
only has 3 channels, and encodes position AND commutation all in those.  
A and B are normal, but the C channel flips the phase relationship 
between it and the other two to give commutation and index pulse 
encoding.  I got the general idea, but I can't say I understand how it 
works.

  Hi All,

I was getting concerned about hotel reservations for the fest,
so I started checking. The economy does not seem to have
depressed the rates. 

Having at the Econo Inn and the Americas Best in past years,
I decided to go slightly upscale. These two do offer the best
rates and while they are nothing to brag about, they were
acceptable. That is except for one thing, I needed workable
internet access and neither passed the test when I stayed
there.

In checking around I was astonished to find that the Best
Western was sold out during the time period, Choice says
they only have one rather expensive room available, and
the Holiday Inn wants almost $100 a night.

My best result was with the Fairfield Inn (309-344-1911).
They negotiated a rate of $69.99 per night for a room
with two beds, two guests for a full weeks stay and provided 
a confirmed reservation number. When asked, they said they 
could offer the same rate to anyone coming to the CNC Workshop 
for the full week.

Re: [Emc-users] EMC Fest 2008

[Dale Ertley]

Mr. Stevenson or Mr. Engvall,
   
  Can you suggest a motel near to the action. 
   
  Has anyone put together a list of people who might like to room and/or drive  
togather and split the cost? 
   
  Thank you
  Dale

 Hello,

 Will there be any good training for newbies at the EMC Fest 2008?

 I am new to EMC. I am also in the process of putting a 4+ axis 
 (xyzw+) full size mill on EMC2.

 Thank you
 Dale

 Dale,
 I attended last year. It was my first year. I attended one class.
 It was very helpful but the most help I found was getting to know the
 developers. I tried to just be an observer. I tried to not interfere
 with their projects. I watched and listened to get a feel for how they
 each thought and worked. All involved are down to earth, quality men.
 It is a pleasure to deal with them. They are very helpful and patient.
 I will attend this year with the same attitude. It is very much
 worth the time, effort and expense.
 thanks
 Stuart

Re: [Emc-users] Decompiling PLC file

[Dale Ertley]

John,
  I will make the list in the next 2 or 3 weeks. By then I will finish reading 
HAL/Classic Ladder and then start the PLC program. If I have problems can I get 
some help from you? 
  Thank you for the assistance

  Dale, In most cases it is better just to write new ladder than to try and

I 
can assist if needed. 

Basicly you need three things:
1 List of inputs
2 List of outputs
3 List of what you want to happen when an input gets triggered.
Start with a pseudo list of what happens kinda like this:
When start is pressed (input 1) 
if is safety circuit is closed(input 2)
if stop is not pressed(input 3)
start motor (output 1)

 The data from these files would be a good starting place for
 developing a Classic Ladder file now that I am upgrading my machine

Re: [Emc-users] restart in the middle of a program

[Dale Ertley]

Hello All,
  Can we look at adding something to the scenario? How about a re-home due to 
lost axis motor steps on an open loop system? How can we restart in the middle 
after an ESTOP? I can't see any need for a reboot of the computer system unless 
we loose electric power.
  Thank you
  Dale

 There's been a bunch of recent email on the list about restart in the

 to do) this?
 
I believe I entered a bug report about 6 months ago when I first 
ran into it.
 Does anyone want to put together a spec for it? In the presence of 
 o-words and looping, the problem is much more complicated than just 
 selecting a line of code
 
Well, if the first couple blocks have an M03 in them, and no M05 
is found later, then the spindle should be on when you get to 
the restart block.
 Questions: continue implies that we stopped. How did we stop? estop? 
 pause? other? After the stop, estop, pause, what can we do? Is MDI 
 active? Jogging? Homing?
 
I think Axis, at least, (maybe it's lower down in EMC) takes 
care of all of the above. If you are currently jogging, homing, 
or in MDI, you can't restart. On machines which lose position 
when E-stopped, the operator needs to re-home. Should be no 
need if just a pause or Esc key. This shouldn't matter to the
way you restart.
 Can we backup a few steps?
 
 
 
 A scenario: On a Bridgeport. A tool breaks during a complex part. Of 
 course that isn't noticed immediately. Finally, we notice and hit (some 
 sort of) stop. We would like to jog the head up, replace the tool, move 
 to some safe spot, touch the tool down. Then raise the head to a safe 
 height, back up the program a step at a time until before the break. The 
 bring the tool back to its current position. Finally restart execution 
 from that point.
I believe that EMC2 does ALL of these steps perfectly. The only 
thing you have to consider is that it is going to do one single 
interpolated (straight-line) move in 3-space from current 
machine position to the position it would have been in just 
before the restart line. This could possibly bring the tool 
into contact with clamps, vise jaws or part features that would 
not be hit when executing the program in its entirety. It 
should be up to the machinist to see that there will not be any 
problem caused by this. So, while EMC2's behavior here is not 
foolproof, it is optimal for the experienced machinist, and 
seems totally adequate to me, except for the spindle.

So, the program is scanned for all other modal effects like 
cutter radius and length compensation, work offsets, why not 
spindle on/off state?

On the typical retrofitted manual machine, the spindle is 
started on the first line and stopped by the M02 at the end of 
the program. Yes, it gets more complicated where the machine 
has a tool changer, but still all that really matters is the 
spindle direction and speed at the line where you restart.

Jon

Re: [Emc-users] Lathe

[Dale Ertley]

On Cerro Alloys.
  Here is a website 
http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=384 
  McMaster Carr also has other Cerro Alloys.
   
  http://www.midwayusa.com/MediaSvr.dll/TechNoteStream?saleitemid=462291
   
  Material:
  
Proprietary Alloy (exact mixture unavailable)

Basic Instructions:
  
Plug the bore immediately ahead of the throat of the chamber using a small 
cleaning patch.
  
Pour the alloy directly into the chamber until full and allow it to cool, it 
will turn a shiny silver color. As soon as it has cooled enough that it is no 
longer a liquid (and doesn't present a burn hazard), remove it from the 
chamber. Take care not to overfill the chamber as the alloy will then run into 
the locking lug area, making removal extremely difficult.
  
During the first 30 minutes of cooling cerrosafe shrinks. At the end of one 
hour it should be exactly chamber size.

Notes
  
Melts between 158 and 190 degrees Fahrenheit
  
Should be melted in a clean iron ladle without direct flame on the product.
  
The chamber being cast should be cleaned thoroughly and a thin coat of oil or 
graphite applied.
  
Reusable

Gene, I do usually have to measure the hole as it is most often the
screw which is missing - or broken in the hole. I can usually get a
pretty close measurement by screwing a wooden cocktail stick or skewer
into the hole and measuring it as soon as it is unscrewed or by using
Plastimorph (Jett Sett) - neither is exact as the wood usually expands a
fraction when it comes free of the hole while the Plastimorph contracts
slightly as it cools but I have always got 'good enough' measurements so
far..

I'd expect the Plastimorph has a pretty well characterized shrinkage that 
could be well compensated for on a % per inch basis though. That however is 
a bulk shrinkage so don't forget to adjust the tpi as well as the diameter. 
The wood would be the more WAG in the 'SWAG' of the two methods by quite a 
bit but probably pretty accurate for tpi right out of the hole as its crush 
is all radial, not axial.

One of the better definitions of good I ever heard came from an ex 
brother-in-law, who was fond of saying that 'its good enough for the girls I 
go with.' :-)

I usually measure them with a travelling microscope over several 
threads.

Oohhhkayy. I had in mind some sort of a dial indicator with a v-tip ground on 
its probe, using the dial to see when you were sitting in the bottom of the 
groove, and an optical scale of some sort to read the intergroove spacing. 
The microscope is obviously an even better tool.

Oh, and you can add at least a hundred years onto the age of 
the screws - not 75 years but 150 - 250 years and some of the screws
probably haven't been moved in all that time until their heads have
corroded off... fortunately, most are blued steel screws in brass plates
and so they will 'disappear' in an Alum solution after a few days.

Presumably with no damage to the brass? And whats a few days if its 200+ 
years old now. :)

I'm not a chemistry major except in the photographic darkroom, where I have 
for many years concocted my own color print paper developer cuz the 
commercial stuff is so hot it fades by the minute and you can't mix up a pint 
because no two prints developed 20 minutes apart will be developed alike. 
With my method, I can make 8 identically exposed 8x10's give me 8 identical 
prints with that pint of mix and a few hours of rolling a uni-drum. But now 
that things are going digital its easier, but I cannot say the quality is the 
same as the optical is/was. Digital has a ways to go yet.

Sounds like an even better solution (pun intended) than using edm to remove 
the remains, edm is not fussy what it takes with it if the electrode aim is 
poor. I would certainly feel like I had violated some sort of a priceless 
artifact of a lost art if I actually damaged the big stuff.
