[Emc-users] connecting up spindle to mesa 7i76 card

[andrew beck]

Hey guys..

this has probably been rehashed a few times but did some google searches
and couldn't find it so am asking here

I just want to connect my mesa 7i76 spindle outputs to my vfd.

I will use 0-10 volts control speed reference and a forward pulse and
reverse pulse.

I am not sure what actual pins I should be using though and am slightly
confused.

any help would be appreciated

regards

Andrew

Re: [Emc-users] shipping touch screen to new zealand from america

[Bari]

Do you have the weight and dimensions of the monitors?

I have had to get used auto parts from a boneyard that doesn't ship to 
me. One option is to have a messenger service pick up the merchandise 
and take it to a Kinkos/Fedex for packing shipping.

Re: [Emc-users] shipping touch screen to new zealand from america

[Chris Albertson]

How big are they?  A large flat rate box to NZ is about $65.   But if the
box is actually "massive" $350 might be a good price for express delivery.
Are they 60" screens or 10" screens?

Re: [Emc-users] Open source CNC architecture

[Robert Murphy]

Hi Raff,

With Linuxcnc you have the ability to get the sources from git and build
a "Run In Place" setup, doesn't affect your main install and lets you
try out a new version.

I have been thinking of a way to have one Livecd with RTAI & RT_PREEMPT
kernels and matching Linuxcnc editions. A plugin overlay similar to
Salix or Puppy Linux is what I've been thinking of,

but would require creating boot scripts and I feel new user trying it
out may get confused. This is despite how much information is
given.Users tend to gloss over READMEs and instructions.

Luckily running Linuxcnc is not as complicated as a cloud service and
The Management from Above doesn't get involved. If you read the forums
you'd get an idea of some of the things.

Anyways Mate whilst we may not agree on some things there'll will be
some areas where we may.

One more comment on application distribution. It's based on my
experience from few years ago where "cloud service" was designed on
Centos distribution. Programs, libraries, and configuration files were
packed as RPMs and installed as such. I proposed much simpler and more
flexible packaging, tar files as in Slackware. The advantage would be
in architecture where more than one version of service could be
installed in parallel without interfering with another one.

Active service would be a link 'from the top directory'. Switching
from one version to another one would be simple:
- service  stop,
- relink top directory,
- service  start.

What we were doing was order pizza, stop services, install RPMs on top
of old ones, start services. That process took about 3 hours on all
servers in the evenings when the network traffic was low across the
USA.

In some instances QA requested we roll back. Argghhh! Obviously, same
install process that lasted another 3 hours or so ... My proposed
architecture would be done in less than 15 minutes in my estimation.

Think about LinuxCNC and it's packages. Using Slackware method you
could try to use different version of LCNC to see if it's good for
your CNC setup. If the new version fails (breaks your tool?) you could
run "cnc-admin script" to roll back, i.e. relink the app to previous
version and start it.

/opt/linuxcnc-v2.6/bin  <- binaries or scripts
/opt/linuxcnc-v2.6/etc  <- config files
/opt/linuxcnc-v2.6/lib  <- libraries
/opt/linuxcnc-v2.6/man  <- manual pages

Latest release would be:
/opt/linuxcnc -> link to /opt/linuxcnc-v2.8.
Your path to LinuxCNC binaries or scripts would always be
/opt/linuxcnc/bin etc.



Dunno why you are calling that the "Slackware Method" and I've been
running a 24/7 Slackware server for years. Never in all my years I have
seen that method used in Slackware or mentioned in the docs. Actually I

Really?
http://docs.slackware.com/slackware:package_management
" Slackware packages can be found with any of the following extensions:

    tbz - Slackware package archive compressed using bzip2
    tlz - Slackware package archive compressed using lzip
    tgz - Slackware package archive compressed using gzip
    txz - Slackware package archive compressed using xz

... Slackware does not automatically track dependencies and install

What's simpler than that???


can't recall any official Slackware packages installing into /opt and
linking as you say. Have you used Slackware ?


Slackware is the first one I used in 1994. Before Ygdrasil, Redhat,
Mandrake, and Debian.

Don't take everything so literally. I was just giving an example for
files locations and a method to switch versions without major changes.
See above.

Ubuntu uses /srv a lot. Put LinuxCNC wherever you want, /cnc,
/usr/local/cnc for what I care. What I wanted to point out is the
simplicity in managing multiple versions of the same application or
service on the same system if tar was used rather than other packaging
system. Dependencies will always be an issue as it was pointed out in
other threads a lot recently.



Puppy Linux and Salix use a "Plug in" file system for apps. But usually
a squashfs file system that can be loaded on boot.

If you read the Linuxcnc docs you'd be aware of a Run In Place install.
Which is the recommended method before a full upgrade.

I'm beginning to think you don't know too much about Linuxcnc and are
trying a push it something that suits your needs or business model.


Keep thinking. I can't read. I'm glad to see you know _everything_ and 
how things should be. I observe trends in the industry and point them 
out to PC parallel port zealots that suggest using motherboard with 
multicore GHz CPUs, and EPP PCI adapter to push 8 bits at a time. So far 
I haven't pushed any business model.




Why not do your own crowd funding, fork Linuxcnc and pay for someone to
break it up and rearrange it to suit your needs.


That's because I don't have your permission to fork from PPC or as much 
money as you do.


Why did I decide to resurrect this thread? My first response did not go 
through a few weeks ago, and because RaspberryPi came up again recently.

Re: [Emc-users] Non-circular boring. Linuxcnc style.

[Sam Sokolik]

I made a hal component that uses either eoffset functionality or using an
offset component in hal.  It takes the spindle position and dynamically
move the axis to create a polygon..  (and remember - a polygon of a large
number of sides is a circle..)

The comp is only lightly tested.

[Emc-users] shipping touch screen to new zealand from america

[andrew beck]

Hey guys. I have a 2 touch screens for my linuxcnc controlled retrofits
coming from america that is a massive bulky parcel and I am getting charged
really excessive shipping.  the monitors cost 65 usd each but shipping will
be over 350 usd currently to new zealand.  basicely the monitors are in a
massive box that is big enough for both monitors at once.  I just want to
combine them together but my shipping company is useless and can't do it.
So I thought I would post here and see if anyone is close.  don't know if
it is worth the effort but I can always hope.  if you live there and can
help I am sure we can work something out.

regards

Andrew
