Note that sim builds of LinuxCNC work fine on 64-bit systems.

It's only realtime builds that currently require the unified-build 
branch and the Xenomai or RT-Preempt kernel to run on 64-bit.

I would say none, other than the fact that I had a computer with 64
bit on it that I wanted to use.  There are obvious disadvantages,
although these are growing less important as time goes on.  But you
wouldn't want to go 64 bit right now on a machine that is important to
you IMHO

Well, I tried to install ubuntu 12.04 LTS in a VM, but it locks up X all
the time.

However, I've been thinking about exporting to an openSCAD script
through rs274 (or sai through linking tolibrs274.so).

OpenSCAD is quite mature and already has all the primitives you want and
you only need to generate a script that sums the tool-paths and
subtracts it from a block.
It may take a wile to render for larger G-code scripts, though, but I
guess that will be a problem for most if not all imlementations when
things get big.

I don't mind controlling the value with g-code, but this is "jog while

stream.  Not easy to do at the moment, but I have hopes that Michael's
messaging updates will make something like this a LOT easier.

A trim probably makes more sense than a mux, but both could work in
different contexts.  My immediate application is tweaking print
temperature, where a trim seems appropriate.  For other applications
(like the cooling fan) a full override probably makes more sense.  Or
maybe even both with a GUI control panel...

I'll play with the options and see what works, but would rather have
been able to just:

  halcmd --Do_what_I_want_to_the_motion_outputs NewTemp

...or similar.  :)

Ah well...

As Seb says, those pins are outputs from motion, and can be
controlled ONLY by g-code.

I think you can do better than the mux approach though.  For
example, use a summer, and add a manually adjustable (PyVCP
or gladeVCP) "temperature trim" value to the main value coming
from the g-code.

Or maybe you want the trim value to be a multiply instead of an
add.  Depends on the nature of the variable you are controlling.

But the general gist is that you are combining the value from the
g-code with the manual value, rather than over-riding the one with
the other.

Re: [Emc-users] Manually Setting Motion Analog & Digital Output Values

[Javier Ros]

I'm not an expert, but maybe it is because your analog output is associated
with a given axis/joint,

If you remove the axis, so that it is not controlled  by the motion
controller, may be it is possible to set the value as you intend.

In this case the given motion.analog-out-00 is not "hal-wired" to anything
and you cahange the value of whatever input pin was attached to
previously to motion.analog-out-00

Not sure if this will fulfill your needs.

Good luck,

Javier

The motion(9) manpages says that those are output pins from motion, set 
by M67/M68, that you should net in HAL to your analog output device.

I think the only way to change the value on those motion.analog-out-* 
pins is to run M67/M68.

I think you could do this:

* net the motion.analog-output pins in to a mux

* have another input to the mux be unconnected

* connect the output of the mux to your analog output device in HAL

* set the control on the mux to normally follow the value from motion

* if you want to monkey with the value manually, flip the mux control to 
follow the "free" input, and setp the free input pins to your temporary 
experimental value


You could put all this in a nice PyVCP panel with radio buttons for 
selecting "programmed" or "manual" temperatures, and sliders for manual 
temperature settings.

[Emc-users] Manually Setting Motion Analog & Digital Output Values

[Charles Steinkuehler]

I want to switch to using motion analog/digital outputs and M6x commands
for control of temperatures, fans, etc. on my 3D printer, but I can't
figure out how to change these values manually.

When I use  an M1xx code and a HAL signal, I can just use halcmd to set
the desired value regardless of whether or not a program is running, but
I can't figure out how to do that with the motion outputs.  When I try
setting the values via HAL, I get an error:

$ halcmd setp motion.analog-out-00 32
:0: pin 'motion.analog-out-00' is not writable

So how can I update these values manually if a program is running?

It is important to be able to tweak some of these (particularly the
temperature settings) based on how the print is progressing.  Using the
M1xx codes breaks blending, which causes "blobs" on the resulting print,
or I wouldn't be trying to use the analog/digital motion outputs.

Yes, the only way to run LinuxCNC in realtime on 64-bit is with the 
Xenomai or RT-Preempt kernels and the unified-build branch.

If you're willing to go with 32-bit, then RTAI (for Linux  3.4.55, on 
Ubuntu 12.04) becomes an option, and both the 2.5 and the master branch 
will work.

Perhaps I could mention a possible marriage
as all the possible options of machines are very varied
most cannot be simulated unless you use the same stuff that the
machine uses itself
so the machine can be simulated already by the vismach in some cases
just needs knowledge of the tool table and use of a cutting simulator
library libcutsim

Rather than rs274ngc in the code, have a look at sai

I would not quite put it like that. There are some brilliant people out
there. Not all will perform equally on all subjects. As they say, YMMV.

The problem is to get the right minds interested into the "right"
projects ;-)

Ok, I'll take a look. That is not to say that my brain can fit the
N-dimensional world with all associated tricks. But I can try and ask,
at least, stupid questions.

That would be a good idea. The rs274 binary could be used as a front-end
for many other things too. But I guess that would be a matter for the
emc-develop list and a patch in that direction.

Qt is "easy" in comparison to all other toolkits, so, yes, a good option.
The question would be if it is possible to integrate it into an existing
viewer, or take an existing code-frame of reference.

Details of implementation; but still a consideration.

I'll take your word for it and try to ask "semi-intelligent" questions
when I get there ;-)

[Emc-users] Unified build branch and 64 bit kernels

[Eric Keller]

I have a machine that locks up periodically using Ubuntu version 10.
They fixed something since then, and it works fine under 12.04.  I
have been running one of Michael's xenomai kernels on it, but I just
had to reinstall the system due to some careless apt-get activity on
my part (who knew that uninstalling python would destroy your
system?).  What is the current best method of getting a 64 bit capable
branch?  Is it the unified built branch?

Re: [Emc-users] Is there an open source program similar to Vericut?

[Anders Wallin]

Hi all,

I have a feeling many of these CAD/CAM things require more knowledge than
fits in the average open-source developers brain.

the code for my efforts is at:
https://github.com/aewallin/libcutsim

*your* help/patches is required with:
- use of the linuxcnc g-code interpreter (through c++ or python). I don't
think it makes sense to write a new g-code interpreter. Would it make sense
to package the interpreter library into a separate .deb package, if there
are other 'clients' than just linuxcnc?
- GUI and 3D view based on polygon-arrays and vertex-arrays (I've used VTK,
but something lower-level and faster might be better). I would suggest Qt
for the GUI but opinions will differ..
- multi-threading so that the GUI remains responsive and the 3D view of the
model updates while the simulation-engine runs
- actual updates/improvements to the cutting-simulation engine:
-- support for different shapes of cutters
-- support for other G-codes than G1
-- data-structure and algorithm changes for e.g. Dual Contouring or one of
the other improved isosurface extraction algorithms

The README file lists a few references which explain most of the background.
I will try to help and explain how the code works to anyone asking even
semi-intelligent questions.

regards,
Anders Wallin

This is a bit of a sad story... I too have been looking for a simulator
and just tested the above suggestions. (BTW, I am on Fedora 19)

OpenSCAM: depends on dxflib, not available in fedora repos
  --> build fail

gdepth: Last update Nov. 2008. Depends on Python numarray, apparently,
Py 2.7 does not cut it
  --> build fail

Cutsim: Last update ~2years ago. Uses external ngc interpreter and
tooltable. After some minor g++ code fixing compiled. Running on an
example --> Segfault


Of the above, only OpenSCAM seems to be in active development.

Re: [Emc-users] XHC HB04 pendant buttons and debouncing

Thank you all!

I tried to go 2nd way by using ready HAL components. To my surprise 
toggle2nist does not toggle actually(!). Is it a bug?

Then I used and connected toggle component with debounce parameter to 
toggle2nist. And it works fine now.

I made corrections to the driver for the numbers to appear exactly the 
same like in the usual UI - I added round functions.

The operator will test, use the pendant, I will fix bugs, problems 
found.. I will share the files later.


By the way, there is one problem with the pendant:
sometimes, when it is left untouched for at least several seconds, it 
stops updating its display. For example, when the program is running or 
machine is jogged by a keyboard. And when you touch smth on the pendant, 
the display updates. Maybe somebody feels why this can happen?


Tomaz, as this was the machine with trivial kinematics, there where no 
joint mode. But.. yes, it was not so easy to set the modes up. I used 
logic xor component, wired its output to one of its own inputs and 
halui.mode.is-... to xor input. This way the signal asking for some mode 
is high till it gets desired mode.

I think there is an argument for doing that _and_ running a cut simulator.
You feed the CAM system with a smooth shape, that spits out G-code, then
you can run a simulator and see what shape you will really get, with the
lumps and bumps and missed bits and gouges to bits that shouldn't have been
touched.
You might then, for example, decide on a smaller stepover, or to run the
finishing cuts in a different direction, for example.
