[Emc-developers] FlipFlop

2017-11-16 Thread andy pugh 
Someone on the forum has noticed that the output pin of the Flipflop
component is of IO type

This seems slightly odd. (It is a compnent that has had very little attention)

It looks like (I'm no expert on the code behind comp) that 
it might actually be functional to set or clear the FF by 
writing a value to out.  So, almost no way to tell if anyone 
is actually USING it that way!

Yes, I tried it and it works as expected (setp-ing the output true or false 
sticks )


Whether is was intended to work this way, perhaps only the author knows.

At the risk of showing my age, I think you could do this on some early (RTL) 
hardware flip flops...

Yes, any FF that pre-dates the master-slave FF will be able 
to be set or cleared by jamming the output.

Is it in fact capable of presetting the flipflop?

Maybe thats one of several problems in my g0704's camera controls as I 
used it as a memory cell to tally whether it was in cutting position or 
in camera spot finder position.  And its not working 100% of the time. 
Just one of several problems I need to sort the rattlesnakes out of 
before its 100% usable. The halui stuff supplied to move the machine  
with the latest camview (see campy.zip) just doesn't work, (the camview 
stuff before didn't either) and I thought it was me. So I wrote my own 
position toggle, with a tally pin in pyvcp to tell which position its 
in. But thats as far as I got when it all went to hell from a short and 
I wound up replacing both the computer and the 5i25. And I've not gotten 
back to the camera since. 

So I go back out and remove the comments from in front of all the camera 
stuffs, and once again linux has thrown gtk under the bus: Here is a 
screen capture of that batch of errors (this ran ok 2 months back)

gladevcp: auxiliary dir: /usr/share/linuxcnc/aux_gladevcp/NativeCAM

AttributeError: 'NoneType' object has no attribute 'set_title'

Do I file this against wheezy, which will never be fixed. or is there a 
syntax change I can make to this line in the .ini file:
EMBED_TAB_NAME  = Camera
EMBED_TAB_COMMAND   = gladevcp -x {XID} camview.glade

That will make it 
The camera window, when selected by its tab, is blank white.

Here is that problem, in that camview.glade:

  

How can I edit that to make it use any version equal to or newer than 
that 2.24?

First, there is not a libgtk+ of any kind in the repos's or installed.

But there is quite a list of stuff with GTK2+ in the descriptions. But 
which will preserve its function well enough to work.

FWIW, the camera is working right now with qv4l2 as the viewer. But AIR 
if I expand the window, it dies until everything is restarted if it has 
to expand the resultant image vertically to keep up with a viewer window 
resize.

Sigh...

Thanks all.

Chuckle, yes you are showing your age, me too as I can also remember 
that. However, I rewrote that code and it doesn't use the flipflop 
anymore. #3998 used as memory now.

Unfortunately, I must have forgotten to enable the halui stuff, none of 
it works now. Yeah, I forgot the "HALUI = halui" in the ini file. Now 
its all triggering but not sure its working 100% yet. I need the camera 
working to calibrate the rest of it.

See my other post about missing gtk+2 stuffs.

[Emc-developers] how to change arm robot config

2017-11-16 Thread Thắng Lê 
Hi,

Is there anyway that i can change robot config? Example in pumakins, there
is a flag call "iflag" that discribe the config of elbow, shoulder and
wrist. I want to change the elbow config of robot from up to behind. i
already tried make a new hal pin for kinematic then set this pin to change
iflag from M code but it does not work.

[Emc-developers] lets try this again. In about 24 hours this post has not echoed from the users list

2017-11-16 Thread Gene Heskett 
Greetings all;

Trying to get the camera on the g0704 to work, I composed a msg showing 
the error and asked for help solving it.  Sent it last night but its not 
come back from the list, so we'll try the developers list this time. 

The error is that the new CamPY.zip installs a file linked in the .ini 
file like this:

EMBED_TAB_COMMAND   = gladevcp -x {XID} camview.glade

That file "camview.glade" in turn has a line thats apparently bogus for a 
wheezy install:


  

And that file is not available for wheezy. So IP get a blank white screen 
where the camera should when that tab is selected, and these squawks 
when linuxcnc is launched.

Is that files function now in a different file?
