There is a lot that has to be done correctly or at least the same way on
each computer.   There are some arbitrary choices that need to be made the
same way all across your network.

You don't provide us with any information at all about your problem so I
can't find it for you.

In general
1. files when they are created have a set of permissions by default.  Many
times the default is set so that only that user can read or write to the
file.  Sometimes the default is that others can read but not write.   You
can see or set the default with the "umask" command.

2 how do you manage users?  Are you copying there /etc/passwd file around
to al the machines or using a centralized database

3 How are you copying files.  Are these Windows shares, NFS or what?

4. some systems set up a group for each user and some don't.  Some people
call these private groups.  If you use this convention it should be on used
all the machines

There is just WAY to much to list, tell us what you are doing, the exact
error messages and the results of "ls -al" on both computers

Re: [Emc-users] Linuxcnc on arm

[Dave Cole]

>>doing it with x86 isn't very feasible.

Why not?   Unless you have serious space or cost constraint issues
going with a PC based solution is still your best bet.  What are the chances of 
you finding a replacement ARM board of the
proper type 10 years from now.Siemens routinely uses PC components in their 
CNC systems.
The #1 failure point for PCs used to be hard drives.
The #2 was power supplies (for me).

SSDs seem to have fixed the #1 problem.
A careful selection of power supplies seems to work for #2.

I've been retiring PCs for the last few years not because of failure but 
because they either draw too much power, or the hardware is becoming too old, 
lacks the desired performance and may no longer well supported by the software. 
 The PCs are usually still running fine when they are removed.

>>Reality is that when you want to sell
equipment, most will run far and fast from self retrofits.

I think that depends greatly on the quality of the retrofit.   Is there a 
wiring diagram?  Is there a backup of the computer drives?

Who wants to use and maintain (if it is possible) an original CNC control
made prior to 2000 ??

All such problems went away when I switched from NFS shares, to sshfs 
shares.  Maybe a little slower because of the encrypted link, but the 
total lack of problems more than makes up for it.   Dr. Nickoles Klepp 
haunts at least 2 of the lists I am on, including the debian-user list 
IIRC, and he can walk you thru setting that up, which is not as complex 
as setting of the NFS stuff, and when done, because the keys are already 
registered, you don't even need your pw to do an ssh -Y nameofmachine, 
the ssh key IS the login.

Much much more pleasant to work with than super pickety NFSv4.

Re: [Emc-users] Linuxcnc on arm

[ceenbot]

There isn't a need to exchange parts once they are in place.  Board 
manufacturers get by with flash gold plated connectors because they are lower 
cost and the flash plating is only good for so many swipes before the connector 
cannot meet its original spec of contact resistance, current capacity, etc.  
The spec for PCI connector plating Finish 4 is a mere 2 mating cycles.  If 
subject to any vibration like my pneumatic ATC exhibits on the machine it 
wiggles the contact surfaces just a little and chafes a bit more.  My pick and 
place accelerates its carriage to maybe 1-2m/s with Sanmotion drives and 
servos.  You can feel vibration & movement on the frame of the machine no 
matter how the 1600# machine is anchored down.

My Bridgeport probably started having connector issues after 20 years of use.  
Now maybe once a month I get a servo amp fault or other random issue related to 
the card cage.  I remove the cards and clean PCB fingers with alcohol then 
insert the cards a number of times to get into fresh metal.  This works again 
for a while.  I just need something I can count on without the machine 
faulting.  Then I would make more parts.

There's one of the kernels at about that version number that proclaims it

Re: [Emc-users] Linuxcnc on arm

[Nicklas Karlsson]

1. I have a chosen a DRV8824 for stepper while you use DRV8825 and I think only 
maximum current is different.
2. You talk about TS-4900 or BBB with Cortex-A* CPU there I had chosen an 
ordinary computer.
3. Instead of FPGA I have chosen cheap STM32 micro controllers.

I work with electronic development so it is important for me to familiar with 
these micro controllers while you just want to get machine running. I tested 
timer output switching at around 4MHz with DMA update of compare value a few 
hours ago. I also use same micro controller for servo motors, it is more or 
less built for this purpose.

Do you have to exchange your SATA and PCIe devices very often? I only do

Re: [Emc-users] Linuxcnc on arm

[ceenbot]

I second the point about not using a PC.  Most of the CNC reliability issues I 
see are with backplane card edge connectors for DC servo drives and connectors 
subject to vibration/chafing of gold plating and oxidation of tin plating.  A 
consumer grade PC motherboard is not meant for machine vibration.  USB 
keyboard, PCI slot and SATA connectors seem to be a weak point as their 
insertion lifetimes are on the order of 50 or so.  I would prefer a 1 or 2 PCB 
solution with tightly coupled interconnects (possibly soldered) board to board 
just to eliminate potential sources of connector failure.  

My still functional 29 year old Bridgeport Interact 412 uses a Heidenhain 151 
CNC controller.  It's 12MHz TMS9995 microprocessor is surrounded with TTL 
counters for encoder position and associated logic that generates 0-10V spindle 
and brush DC servo command data.  Any single core 1GHz A9 would run circles 
around what I have now. The cost of a PC versus a purpose-built embedded CNC 
controller is not an issue for me as long as the controller does not creep into 
the thousands of $$.  Machine reliability and up time come first but safety is 
right up there as well.  You can imagine what servo runaway is like when an 
encoder cable is broken.  In my case mouse chewed.  

I've been following the BBB discussions and think the BBB would work for the 
networking & GUI and any RT servo timing should be handled by a FPGA.  The 
BBB's 200MHz PRUs are OK for a simple 3D machine but my 6 head pick and place 
has X & Y axes, (12) Nema 11 stepper motors and 112 pneumatic feeders.  A 
little beyond a BBB's I/O count.

We developed a FPGA based stepper algorithm using the popular DRV8825 Reprap 
microstepping driver.  The 8825 phase current is dynamically varied based on 
RPM and these tables are stored in the FPGA.  Changing phase current vs. RPM 
allows us to tune around motor and carriage resonance points.  We took a Nema 
17 stepper and had it spinning at 3000RPM with 40-bit speed resolution.  At 
full speed the 32x microstepping clock was 320kHz.  Probably something a PRU 
could do in assembly language but is more flexible with VHDL.  

I'm considering the BBB and a Spartan-6 cape for ~$100 and the Zynq-based 
Snickerdoodle for $62-$157.  The TS-4900 also looks appealing.

We now have our second wheezy based machine running in our shop, with 2 
Ubuntu machines still kicking around as well. I have all of the machines 
connected to our network, that way all of the programming in the office 
can be dropped directly in the respective nc_files folder on whatever 
machine they may be running. On the Ubuntu machines, I have never 
noticed any kind of permission problems when copying files back and 
forth between PC's, whether it be between 2 Ubuntu PC or even 1 windows 
PC and 1 Ubuntu PC. But now I notice that we can still freely copy files 
from the Ubuntu/windows PC to the Wheezy machines, but once we open and 
edit a file on the wheezy machine, we cannot  *from the windows/Ubuntu 
PC* copy the file in question back into the windows/Ubuntu PC, I am 
getting "Error while copying yada yada yada, Permission Denied". On the 
Unbuntu machines, we can remotely, from in the office, get into the 
Ubuntu machine, and copy files out of those machines, and have no troubles.

Any thoughts as to what I may need to do, to allow us to copy back and 
forth with out permission problems?

Re: [Emc-users] Servos and Drives

[Dave Cole]

I've used Automation Direct servos and Teco servos for Brushless 
applications.   I think the Automation Direct and Tecos are very 
comparable.I use the Automation Direct breakout boards on the Teco 
drives to make wiring easier.The terminal wiring numbers don't match 
up but once that is sorted, it works great.  I've lost count of the 
number of Teco's I have setup.   I'm doing 6 right now but they are not 
for CNC applications.   These will be controlled via PLCs.
I used some DC brush analog drives from Anaheim Automation (I think) and 
they worked fine on a DC servo retrofit with LinuxCNC.
Teco sells via Machmotion and a few other US distributors.  FWIW, I was 
working on a Flow Waterjet yesterday and the customer (a guy I have 
known for almost 20 years) recently sold off a Machmotion retrofitted 
Plasma cutter.   This guy is really smart and an ex-controls engineer 
and he said the controls absolutely sucked and he couldn't get the 
machine to run reliably.I've got LinuxCNC running another Flow water 
jet so he wanted to know about the previous retrofit with LinuxCNC.

Re: [Emc-users] Puzzling Realtime Delay

[John Thornton]

He is getting a realtime delay error, I didn't know if the pae line had 
anything to do with it or not. It' puzzling because the latency tests 
don't show anything out of the ordinary.

That's my fault.  After all the work i did on the Linux 3.4/RTAI kernel,
i actually forgot to enable PAE.

It shouldn't hurt anything, except you can only use the first 3.5 gigs
or so of RAM.

An analog velocity servo, pretty much by definition, does 
NOT use the encoder, but a tachometer, for velocity 
feedback.  (Fanuc used analog velocity servo amps, but 
derived the tach signal from the encoder, not a physical 
tach.)  There are some "digital" velocity servo amps that 
use an encoder for velocity feedback, yet take analog 
commands from the control.

You are talking about an analog velocity servo amplifier?

Servo Dynamics
AMC
Copley Controls

Are three that I know about, and are still in business.  
There are plenty more that are of historical significance.
Fanuc, Fanuc/Gettys, GE HiAk, Westamp, Contraves NC400, 
Kollmorgen and many others.

Re: [Emc-users] Linuxcnc on arm

[Nicklas Karlsson]

ARM-Cortex-M* CPUs have a nested vectored interrupt NVIC controller with 
selectable interrupt priorities. The NVIC is suitable for real time scheduling 
according to rate monotonic, FreeRtos may be added on top if needed, in 
particular there is nothing uknown disturbing. There are plenty of micro 
controllers using this and interrupts may be from peripherals like timers or 
communication buses. The micro controllers usually have suitable perihperals 
for control of motor switches and in some cases switches for switch mode power 
converters.

Maybe you do not have to dream for long: There are support communication 
although currently broken via NML. These micro controllers are cheap and common.

There are also ARM-Cortex-A* CPUs usually with better performance but I do not 
know if they have the NVIC. I do not think the ARM-Cortex-A* come in devices 
with peripherals suitable for control of power electronics. I think the 
ARM-Cortex-A* is more suitable for tasks similar to an ordinary desktop 
computer.

In short:
  Embedded for real time tasks without graphics => ARM-Cortex-M*
  Graphics => ARM-Cortex-A* or the usual X86.

Re: [Emc-users] Servos and Drives

[Nicklas Karlsson]

No I looked for suitable drives and decided to make my own drive. It is a 
simple modular design with a little bit to many cables coming to fruitin now. 
Then done it should be easily customizable and able to drive all the common 
motors with resolver/tacho/encoder for measurement.

Yes, and it is scalable,

That drive is loaded with so much when it comes to the control and 
programming aspect, it is pretty amazing everything you get for how much 
they charge.

Re: [Emc-users] Servos and Drives

[Rick Lair]

The I/O cable was a little messy though, I used a ZL-CBL50-1P, that had 
the connector for the drive end, and flying leads on the other to direct 
wire to my 7i70/7i71/7i49, next time I will go with the ZL-SVC-CBL50 and 
a ZL-RTB50. That was a whole bunch of excess little 28AWG wire floating 
around in my wire trays, I only needed like 8 or 10 wires out of the 
cable, so that left almost 40 little wires loose, tried my best to clean 
it up, without just cutting them off.

Hi Rick,

Does the drive pass the encoder pulse through to the control card?

Hi Rick,

I was just looking at Automation Direct, good to hear from someone that 
has used them.

Thanks

Re: [Emc-users] Linuxcnc on arm

[Todd Zuercher]

That is simply because the majority of people want to be able to call up the 
manufacturer and get an answer or have them fix it when they have a problem.  
That doesn't happen with retrofits.

Anyway, that is just dreaming.  Reality is that when you want to sell
equipment, most will run far and fast from self retrofits.

Hey JT,

I used a 3KW system from Automation Direct on our rotary table, and it 
was a pretty seamless install/setup with linuxcnc, and for the price it 
was really reasonable.

Does anyone have links to servo/drive suppliers in the US that have the 
plain vanilla velocity drives that we like to use with LinuxCNC?

Thanks

Re: [Emc-users] Linuxcnc on arm

[Erik Friesen]

I don't want bang for my buck.  What I want is a control board I can drop
into my haas, and doing it with x86 isn't very feasible.  Dropping a
embeddedarm ts4900 on a custom baseboard would be real slick, and it seems
that it could surely compete with the 1990's era motorola running at 40mhz.

Anyway, that is just dreaming.  Reality is that when you want to sell
equipment, most will run far and fast from self retrofits.
