Re: [Emc-users] update from 2.8 pre ja9 to latest on ubuntu 10.04 ... pyton3 problem??

[Gregg Eshelman]

An industrial PC board may work. A quick google for newest motherboard with ISA 
slot turned up ones like a IEI IMBA-G412ISA-R20 G41 which takes an LGA775 Core 
2 (1 to 4 core) CPU and has one ISA, one ISA/PCI, four PCI and one PCIe x16 
slot.
Another option is the MB-P4BWA. One less PCI slot, replaced with another PCIe 
and looks like it also has a Mini PCI slot. 6x SATA ports and dual gigabit LAN 
among other features. Also an LGA775 CPU.

There are others, looks like the newest CPU you'll find on a board with ISA 
slots is LGA775 and to buy a new board will cost $130 and up, up, UP. Find the 
board you want then hunt for a deal on a used one.
A server board may be usable, though they tended to not have the fast slots 
like VLB, AGP or PCIe for video, while retaining other old standards longer 
than boards for the office and consumer markets.

I'm sorry to hear about that problem.  We tried to ensure that our 
Wheezy RTAI kernel worked on as many old computers as we could, but 
clearly there were some that we failed to support.

   I don't know if this is the type you are looking for, but I did a 
quick search, and found this 2x2 housing on Amazon: 
https://amzn.com/B00F8APVQA

   If this IS what you are looking for, you will also need these two items:
Pins - https://amzn.com/B00XDSPACE
Pin crimper - https://amzn.com/B01CE4FAMW

   There is also a male pin that works really well for testing, and 
breadboard use:
https://amzn.com/B0132HFOYO

   These were all quick searches, and not a recommendation of sellers.  
The smallest one of these is a 1x1, and the biggest one that I have used 
is a 2x24.  I use a lot of these type of pin housings in my personal 
designs, and they are quite useful for custom pin assignments.  Just 
google "dupont housing" to find more information than you ever wanted to 
know.

   One thing of note...  These work well, and I have run quite a few 
amps through them without problems (Stepper motors, powers supplies, 
etc...), but they are Chinese made, and neither the pins, nor housings 
are interchangeable with the genuine Dupont branded components (which 
have been discontinued for many years).

Best check that that is right before flashing an SPI firmware onto the
board with an EPP connection. That just sounds wrong

There are files for epp, serial and spi modes, so you can divide by 3.

Looking at the 7i90_spi_svst4_8.bit file (SPI mode, 4 SerVos 8
STeppers)  the actual default pinout will be found in the "source"
subfolder inside the ZIP file you will find there.
The 7i90 is a 72-pin card, so the file that defines the pinout is
PIN_SVST4_8_72.vhd

You will see from that that every pin is allocated, so by default
there are no pins free for GPIO. You make GPIO pins by enabling only
as many encoders and stepgens as you want.
Unused pins become GPIO.

You probably want some of the encoders for MPGs too, so you might want
to use their pins last.

You might also see that the PWMgens have three pin types each, and the
stepgens have 6 pins each (for table mode).

The simplest way to work out the pins is to load the driver with the
number of each function you want, and let it tell you what the pins
are.

Top Tip! Pin1 on the connectors has a square solder pad.

Seriously huge & confusing, must be 100 or more .bit files that are not 
discussed in the docs. I'll need a small bucket of bit io, 2 stepgens, 
an encoder and a pwmgen in the initial profile. Every bitfile discussed 
in the pdf has multiples of those.  Like 8 of everything?  Boggles what 
mind I have left.

So, suggested files to install with mesaflash-3?, once the r-pi-3 is up 
and running of course.  At this point I haven't a clue whats next  after 
the r-pi-3 has arrived.  All I know at this point is that I'll need 
independant lines for fwd and reverse on the spindle motor, an inverted 
pwm, 12v pwr & ground, two steppers, 2 dirs,  some grounds and some 5 
volts.  Everything else can be done with gpio stuffs.  I think this is 
gonna be a serious backache, but certainly no worse than trying to use 
these Mach bobs has been.

Thanks everybody. Head me off before I get to the pass if you can. :)

Yes, it drove me crazy... ;)

Direct link is here:
http://www.mesanet.com/software/parallel/7i90.zip

The bit files are in:
7i90/configs/hostmot2/

You need one of the 7i90_spi*.bit  files.
Then you have to flash the card on your printer port with

sudo ./mesaflash --verbose --epp --device 7i90 --addr 0xd010 --addr_hi 0xd000 \
--write configs/hostmot2/7i90_spi_svst4_8.bit

Change the addr and the filename!
grep the addr from  lspci -v.

The firmware is there:

Click the "Specification" tab (OK, I grant that that is an odd name to

Download that file, and look in "configs" / "Hosmot2"

[Emc-users] Firmware files for 7i90HD? Where?

[Gene Heskett]

John (Thanks John) was Speedy Gonzales, the 7i90HD was in my mailbox 
today, so now I need to study the pdf I downloaded in depth, but where 
do I get the firmware files listed in this document? Google did not spit 
out any links.

They do not have links on either US website.  The pdf yup, firmware? Not 
for a 7i90HD.

According to Amazon, the raspberry pi-3 should be here tomorrow along 
with some u-SD cards. But all I can do is spin motors, the belts have 
not arrived. That may be a good thing. ;-)

And, where can I find the teeny little header connectors that let you 
pickup say a square pattern of 4 connections on the 50 pin connectors to 
drive the stepper drivers with?  Those in the Martinjak pix look to be 
at least as handy as sliced bread!

Thanks.

Duzi was my first research, but no ethernet there too.
But in Austria it's ok! Thank you martinjak!

Now i have a question...
How can i run a tb6560 using a 7i92? Is it direct link or should i put a 
7i76 between them?
I'm sorry, i'm not much familiar with mesa products..
And sorry too for my strange mail answers, but i'm messing with my smartphone..

Thanks, Davide.

Re: [Emc-users] Traj MAX_VELOCITY

[Chris Albertson]

EMC was designed for the general purpose case where a machine might have
more than three axis and all of then not perpendicular.   (Think of a paint
spray robot on an automotive assembly line.)  Or even on a mill velocity
might have effect on the surface finish.

With machines that have a large number of axis some movements can combine
and you have a VERY high speed and acceleration

You may have to, some of the early P4's had a halt bug. It halted, and 
would not recover and a reset or power cycle was needed to get back to 
running. Nice speedy machine, but useless for us.  I moved the drive to 
a Dell 748. Very simple to just plug the cables into the newer machine 
and it ran perfectly on powerup.  And is still running.  Rock solid 
stability now.

The dmesg output will tell if that is the problem as it will report the 
doofy chip as a family 15. Family 16 and up has been fixed.  Family 15 
stuff is also not microcode patchable, 16 and up are. dmesg is your 
friend if thats the case.

We generally do not announce changes in dependencies/OS support in the 
development branch(es), outside of the developer channels.

Once we make a release branch and start stabilizing the code for user 
consumption, we try really hard to communicate this information.  For 
example, the information about supported platforms for 2.7 is here:

http://linuxcnc.org/docs/2.7/html/getting-started/updating-linuxcnc.html

http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_alternate_install_methods

I'm sorry to hear about that problem.  We tried to ensure that our 
Wheezy RTAI kernel worked on as many old computers as we could, but 
clearly there were some that we failed to support.

Ubuntu 10.04 Lucid was end-of-lifed by the Ubuntu folks in May of 2013. 
No new software has been added to that distro for many years.

The LinuxCNC project has started using newer versions of libraries and 
tools that are not available in Lucid.  Unless you (or someone else) 
adds back support for the old Ubuntu 10.04 versions, in a way that 
minimizes impact and doesn't prevent the project from supporting newer 
versions, i think your only option is to stay on LinuxCNC 2.7 on that 
machine.

Re: [Emc-users] Traj MAX_VELOCITY

[dannym]

Should be a limit on the vector sum on linear axes only, and you're right, it 
may or may not be desirable.  The mechanical limits already give the per-axis 
limits.

If you make it "infinite", then you get a notably faster speed on diagonal 
rapids than ones that only go down one axis.  But that's hardly a problem.

Limiting traj acceleration is more meaningful.  The per-axis give mechanical 
limits, but your whole machine may walk across the floor if you combine accel 
from 2 axes on a diagonal.

I think what you're proposing should work fine, if your machine can 
handle it.

[TRAJ]MAX_VELOCITY limits the velocity of the controlled point.  In a 
diagonal move where both X and Y are moving, the controlled point moves 
faster than either X or Y.  Some machines can't handle maxing out both X 
and Y at the same time, and they use [TRAJ]MAX_VELOCITY to limit this 
"diagonal speed" to something the machine can handle.  If your machine 
doesn't have this limitation, then you should be able to set it very 
high and rely on the individual axis velocity limits.

I completely missed that announcement, or was there never an announcement of 
cessation of support for Lucid outside of that on the developers list?

I find this a little troubling, as I have at least one machine that I have not 
been able to get the live image for Wheezy to run on.  It is an older P4 
machine and my attempts to try Wheezy on it have failed miserably, it boots but 
then crashes hard when I try to open a latency test.  Unfortunately upgrading 
the motherboard on this will be very problematic, as it is using an old ISA bus 
card to interface with the cnc machine.

[dragon]

I would say likely not since Ubuntu 10.04 has a much older build tool
stack and the kernel, GCC, python, support libraries, etc. are all much
older.

Re: [Emc-users] update from 2.8 pre ja9 to latest on ubuntu 10.04 ... pyton3 problem??

[Jeff Epler]

The master branch does not support Ubuntu 10.04.

This was proposed over a year ago and no developers offered to maintain the
build on 10.04.

[Emc-users] update from 2.8 pre ja9 to latest on ubuntu 10.04 ... pyton3 problem??

[giorgio foga]

I have already ask in LCNC forum but have not a convincing answer ... in fact, 
who told me he had a chance to test ...


My machine have a lot of customisation and I'm afraid it does not work.


If update from 2.8 pre ja9 I have problem with python3 (in ubuntu 10.04 only 
python 2.7 is possible)

I can have some other issue if update into my ubuntu 10.04 SO??


Regards

giorgio

[Emc-users] queuebuster in 2.7.x ubuntu 10.04

[giorgio foga]

I have remapped  queuebuster on G70 command 


If run LCNC on terminal obtain:


is_callable(remap.queuebuster) = TRUE


at the start of my ngc ... then al other time to call G70 obtain these other 
messages:


is_callable(oworld.queuebuster) = FALSE


because I try to use G70 inside a oworld but at stop motion  /* these is 
normal?? or is because queuebuster not work??*/


These because I try to change some quote from mycomponent with   
#<_hal[mycomp.xvalue]> mechanism inside gcode . the quote changing inside 
osub  all work but I'm not able to control temporary line of changing ... 
sometime   #<_hal[mycomp.xvalue]> is renew sometime is the sema as last but it 
must be new and different every time...


any suggest?


regards

Giorgio

Or even better the USB stick one has always used to avoid even having a
network connection active?

Having replaced a number of XP computers with Raspberry Pi's rather than
the stupidly expensive M$ route of new hardware that could run current
windows OS I can say I've not had any problems with the SD cards over
several years now. I did put Banana Pi's in early on, with SATA SSD
sticks, but the extra cost was probably not necessary.

Moving forward it would perhaps be nice to see a credit card computer
with an mSATA slot on board? But I don't think there is any particular
need for that.

[Danny Miller]

You wouldn't likely save the g-code on the SD card at all.

You'd have a wifi connection and load the g-code from your local network.

Those SD cards are used for storing photos and video quickly. 
Photographers and videographers use TONS of memory over and over., and 
quite frankly I never heard of someone wearing one out.

This isn't a drop in the bucket compared to those high-stress uses. It 
will go obsolete long before the SD card wears out.

They do employ load-leveling where it won't keep resaving over the same 
block of memory.  The file structure is unaware of it but if you keep 
rewriting a cache file, it moves it up and down across the whole SD card 
slowly, so it never wears out.
