Hi all!
I'd like to create a stand-alone DRO, with some function like the "real" ones.
But... I don't understand a thing or two...
Is possible to create a stand alone GUI (without launch Axis or touchy ot others ) that manage encoder
and do some calculation using Gladevcp?
I don't' want to integrate in axes, but I'd like to make it indipendent...
I hope I explain...
Greetings

Sure you can do that with just HAL and GladeVCP. I have some tutorials on my web site about creating different things like that.

Yes.
My approach (there are others) would be to write a HAL file to load the required HAL components (like encoder counters) and to launch the GUI.
You can then load RTAPI and the HAL file with
halrun -I -f yourhalfile.hal
This could be wrapped up in a file (made executable) containing
#! /bin/bash
halrun -I -f yourhalfile.hal
Your HAL file would, at a minimum need
loadrt threads name1=servo-thread period1=1000000 name2=base-thread period2=50000
loadrt encoder count=3
addf encoder.0.update-counters base-thread
addf encoder.1.update-counters base-thread
addf encoder.2.update-counters base-thread
addf encoder.0.capture-position servo-thread
addf encoder.1.capture-position servo-thread
addf encoder.2.capture-position servo-thread
loadusr (Typical GladeVCP startup stuffs)
net x-pos encoder.0.position gladevcp.display.0
net y-pos encoder.0.position gladevcp.display.1
net z-pos encoder.0.position gladevcp.display.2
start
The only unusual things about this HAL file are that it needs to load threads, and it needs to start the threads.
Typical DRO features like zeroing counts and entering the actual position could be handled in either HAL or GladeVCP Python (setting arbitrary position would be pretty painful in just HAL, but not impossible)

Hi again.
I was trying BigJohn tutorial (part3, install your own gui).
I'm running everythings on a virtual machine, with win7 as host.
I have two problem
1) When I launch the gui the HAL GREMLIN component hang-up the system, so I have to reboot. If I cancel gremlin from the glade file, the gui run right.
2) I have installed the gui (gui3.glade), made the modification, but when I try to launch it I obtain this...

I dont think you can run real time configs in a virtual environment
I would try a 'sim' environment/kernel for a virtual machine

That's right.
In fact I installed sim version and it runs.
After that I find that HAL GREMLIN crash the system, maybe due to opengl conflict, even if xlgears works.
So I have to use glade touchy instead, for example.
At home, with a real system, I was able to create my "personal" panel with 1 axes DRO.
Now I have to understand how to "create" the DTG function like in the Axis's DRO tab, where destination will be define by the DRO function that you are using.
Is possible to integrate a touch in the DRO system to zero the axis?

i'm trying
BigJohn tutorial
.
I have modified a little the GUI part, and adapt the file to mym files names.
but when I launch it I get this error
What could be the problem?

Did you copy the file to the installed location?

Yes.
At the end I follow step by step the tutorial, using the file I've downloaded from the site...
I used also sudo cp ...
Could be that the problem is I'm using sim linuxcnc with e sim configuration?

Yes that could be a problem... I've never ran the tutorials on a sim or a virtual machine.
