 Hi
 I would like to install virtualbox on EMC ubuntu, but it keeps telling me 
 that I need a kernel module / header file.
 In /var/log/vbox-install.log it says
 Makefile:127:*** Error: unable to find sources of your current linux 
 kernel.  Specify KERN_DIR=directory and run Make
 again. Stop.
 Thanks again

Re: [Emc-users] Virtual Box

2008-05-06 Thread Alex Joni
try sudo apt-get install linux-source-2.6.15-magma
that should install the linux source, maybe vbox works then.
If you only need the headers then apt-get install linux-headers-2.6.15-magma 
(it's most likely the full source is not needed, so I would try this first).

Alex

2008-05-06 Thread Anders Wallin
 Is there any benefit to be found with the real time kernel by disabling apm 
 or other features with the kernel parameters?
 For example acpi=off  apm=off etc?

adding these two to the line that starts with 'kernel ...' in GRUB 
doesn't cure the problem.

I will try a PATA hdd today and maybe then I'll switch to another computer.

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.

[Emc-users] helical code

2008-05-06 Thread Dave Engvall
Hi,
I'm milling a tapered hole using helical interp.
The program works fine but can't keep up.
With a HSS ball mill I've been millling at 4 ips.
With carbide I could raise that to 10 ips.

At either speed it maintains speed 'til about 1/2 way thru the  
program then starts to pause and go, pause and go., etc.
I tried G64 P0.001 and that didn't help.
Am I missing something?

The following is a snip of the code about 1/2 way thru the program.

I'm not sure exactly what formal classes there will be.  I hope 
we can have something more organized than last year.  Ray Henry 
will be there, so that is likely to be a guarantee!  But, even 
without formal classes, we will have a true EMC critical mass 
there as usual.  Just buttonhole one of the developers and ask a 
question.

I'm planning on doing two classes that are oriented a bit toward 
my products.  But, maybe I need to do a general class as well, 
mostly focusing on the retrofit process and selection of components.

If you don't have EMC running yet, bring your computer and we 
will get it installed and at least partially configured for your 
own setup.

   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

Ray Henry is planning classes - I believe he is going to have several 
computers networked together and hooked to a small mill so students 
can actually run the machine.  I'll let him fill in the details.

[Emc-users] Master-Slave stepper set up

2008-05-06 Thread Mark Wendt (Contractor)
I've in the process of building a two axis machine - using the X and 
Z axis, and I have a three axis stepper/driver combo already set up 
and basically ready to go.  I was wondering if there is some way to 
configure EMC so that I could slave the Y axis to the X axis. and use 
two steppers, one on each side of the gantry.

Thanks,
Mark

Re: [Emc-users] EMC Fest 2008

2008-05-06 Thread Dave Engvall
You get to take your chances. Several of the attendees stayed at the  
Econo Inn. I stayed there two years ago.

They had just changed the beds and the new ones were too firm for me.
I will stay at the Holiday Inn Express which is more expensive and  
farther away; but then my wife will be there
also. The Econo Inn is about as close as any motel I'm aware of.  
Price two years ago was $50/nite.

HTH.

 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

Hi Dave

I'm going to guess that you meant 4ipm.  With that small a helix even
with your Mazak you'd be hard pressed to get 240 ipm.  

I ran your code snippet here and it whizzed through.  But then it isn't

2008-05-06 Thread Ray Henry

Hi Dale

I'll be bringing a few computers that I want/plan to network together
into some sort of 8.04-EMC2 lab.  

My first class at will start at 8:00 am will be a Linux/EMC2 intro.
Monday -- Starting EMC2 in the Ubuntu Linux environment.
Tuesday-- EMC2 operator interfaces
Wednesday  -- Hand coded part programs part 1
Thursday   -- Hand coded part programs 2
Friday -- Part programming assistants

Beyond this I'll plan to be in/around the lab for a couple hours each
day when users can sign up for machines and test ideas and seek help.  

I'm hoping that several others will also offer classes in the lab during
the week.

Ray

Re: [Emc-users] 155 ms real-time delay every 10 minutes?

2008-05-06 Thread Kent A. Reed
Anders:

I hesitate to throw what may be just another red herring into the 
discussion, but there are a number of 600-second defaults floating 
around Linux, and it is possible you're getting tripped up by one of 
them rather than by some clock problem.

For example, by default, the stock Ubuntu 7.10 on my home PC clears the 
ip4 routing table every 600 seconds (defined in  
/proc/sys/net/ip4/secret_interval). I would assume the time it takes to 
do this is dependent on the size of the routing table (this created a 
problem with a Redhat system we built at work to monitor experiments).

I also used to trip over the various ways screen blanking intervals are 
defined in X11, though that seems an unlikely cause of your problem.

It's too bad no one has created a list of all the default times defined 
in Linux distributions (or it they have, it's too bad I'm too stupid to 
be able to find such lists!).

Just my two cents worth. Good hunting!

Kent

Re: [Emc-users] helical code

 Hi,
 I'm milling a tapered hole using helical interp.
 The program works fine but can't keep up.
 With a HSS ball mill I've been millling at 4 ips.
 With carbide I could raise that to 10 ips.
 
 At either speed it maintains speed 'til about 1/2 way thru the  
 program then starts to pause and go, pause and go., etc.
 I tried G64 P0.001 and that didn't help.
Hmm, the G64 P0.0005 made a HUGE difference in the performance 
on a flat XY-plane circle specified in tiny G01 moves.  It sped 
up by 15 : 1.  My test machine is kind of torn apart right now, 
but if you'd send me the whole program I could try it here.

Of course, for tapered holes, a tapered end mill is another 
solution.

The slowing down at about halfway through is a real puzzle.
It seems odd that the user-mode half of EMC couldn't keep up 
with the real-time part.  The program is only about 500 blocks 
long?  I'm wondering  So, you start at the top, with a 
larger diameter, and then get smaller as you go down?  I'm 
wondering if the curvature is just on the bitter edge of 
triggering some limit for merging the line segments, and as the 
diameter shrinks, the trajectory planner switches modes from 
smooth merging of the segments to not merging them without 
deceleration.  I'd guess that P0.001 parameter might have an 
effect on this, you might have to make the P larger or make your 
line segments shorter.

Re: [Emc-users] Master-Slave stepper set up

 I've in the process of building a two axis machine - using the X and 
 Z axis, and I have a three axis stepper/driver combo already set up 
 and basically ready to go.  I was wondering if there is some way to 
 configure EMC so that I could slave the Y axis to the X axis. and use 
 two steppers, one on each side of the gantry.
There are much better ways to do this.  Depending on the motion 
hardware you have, this slaving can be done in the HAL layer, 
and once it is set up right, you never need to know there are 
two motors moving in unison again.

The tricky bit is to figure out how to get the two sides of the 
gantry synchronized so the machine is square and not 
distorted.  The large gantry mills have bearings in the gantry 
towers so that when the gantry sides are out of sync a little it 
doesn't stress or break the machine's structure.  Homing the 
axis brings both sides to preset alignment with individual 
sensors.  I'm sure there are ways to do this easily in HAL with 
a couple AND gates that shuts off steps to the motor that 
reaches home first, then waits until the second motor gets there 
before completing the home sequence.

This gantry scheme is called a tandem axis.

All the above is true.  But, you can also bring your camper/RV

 Anders:
 
 I hesitate to throw what may be just another red herring into the 
 discussion, but there are a number of 600-second defaults floating 
 around Linux, and it is possible you're getting tripped up by one of 
 them rather than by some clock problem.
 
 For example, by default, the stock Ubuntu 7.10 on my home PC clears the 
 ip4 routing table every 600 seconds (defined in  
 /proc/sys/net/ip4/secret_interval). I would assume the time it takes to 
 do this is dependent on the size of the routing table (this created a 
 problem with a Redhat system we built at work to monitor experiments).
 
Anything happening in IP routing should be totally unable to 
affect the RT system.  Maybe it does something else at the same 
time that triggers something in the ethernet driver, like a big 
DMA burst.
 I also used to trip over the various ways screen blanking intervals are 
 defined in X11, though that seems an unlikely cause of your problem.
Some of the computers with on-board video handle certain things 
in BIOS ROM routines, and these can cause upsets to the RT 
environment on some machines.  Sometimes you can turn these 
things off, or set them to be done by Linux-level software 
rather than hidden features, by turning down the X-windows 
acceleration support in the configuration menu.  I can easily 
see how a screensaver could trigger some bit-blt activity that 
might have side effects.  I think this one is well worth pursuing.

 Hi all,
 
 The documentation for the debounce component shows the syntax as:
 loadrt debounce [cfg=size[,size...]]
...

In the next release, the debounce component will be changed so that it
matches the documentation (using spaces to separate options).  If you've
used spaces to separate options, you will have to modify your .hal files
when this release is made.

Re: [Emc-users] EMC Fest 2008

2008-05-06 Thread amtb

Hi
I want to ask about Wednesday  -- Hand coded part programs part 1
Is this programming with G code?
I think that use G code to program part possible to find in every
community college. Help in G code programming is every way.
What is impossible to find it is EMC2 inside. Learn how to make special G
code for example 555- G555 with special move is much more important. To
learn about G code programming do not need to go to EMC2 fest.
Unfortunately the are one place to find about inside architect of EMC2 and
it is EMC2 fest.
I think that need to establish on line school about EMC2 structure  and
use ENC2 FEST as a culmination point. I am sure that tuition fee should be
applied to on line school!

Thanks
Aram



 Hi Dale

 I'll be bringing a few computers that I want/plan to network together
 into some sort of 8.04-EMC2 lab.

 My first class at will start at 8:00 am will be a Linux/EMC2 intro.
   Monday -- Starting EMC2 in the Ubuntu Linux environment.
   Tuesday-- EMC2 operator interfaces
   Wednesday  -- Hand coded part programs part 1
   Thursday   -- Hand coded part programs 2
   Friday -- Part programming assistants

 Beyond this I'll plan to be in/around the lab for a couple hours each
 day when users can sign up for machines and test ideas and seek help.

 I'm hoping that several others will also offer classes in the lab during
 the week.

 Ray
