can you verify, if it shows the same in the sim config?

Looking for some advice on a build.  This is what I have.  Would this work?
2 - Allen Bradley N-3412-2 motors.
2 - Allen Bradley MPL-A310-MK22AA
3 - Allen Bradley Ultra 3000 drivers
I also have several Allen Bradley Logix 5561, logic 5550, and other hardware

Do I need Allen Bradley software to run the motors?

I have. A lot of experience with CNC routers and computers. I am a novice when it comes to programming but I am willing to learn. 

I am looking to build a 4x4 CNC with a spindle.

RE: custom_postgui.hal:67: Pin 'halui.program.is-idle' was already linked to signal 'prog-running'

try replacing:with:

What you tell me is what I do but when I get to the encoders, only encoder A appears. And when I go to the THC configuration page, the option to choose encoder does not appear.

See here, has not published the kinematic though:


Closed loop for the motors is not a problem.
Backlash compensation is possible in linuxcnc but don't expect it to make the problem go away completely as the PID loop will have it's problems coping.

I'm currently having trouble connecting to ethercat after compiling linuxcnc from source. If you have made further progress on this or ethercat related issues, I hope you can share.
thanks.

Thank you, it can run smoothly now.     I guess it failed because there were Chinese characters in my installation path.Now I want to try how to directly start LinuxCNC and Stepconf Wizard on the desktop, without having to set up the environment in the terminal every time,  as shown in the picture. 
 Your dog is very cute!!!  

The 7I96S_7I77 configuration moves the 7I96S encoder to encoder 6 (and aliased encoder 7)
This was done to be compatible with 7I77 configurations that expect the 7I77 encoders
to be encoder numbers 0..5

Note that you need to set num_encoders=8 (or leave the num_encoders
out entirely) to access encoder 6

 

THANKS I increased the Z travel distance to 7" and that seems to have cured the problems. I did not get the errors and I an repeat the surface detection over again with out a error too.

Not the same drives, pretty sure, this one is step/dir only, the above is analog only.

The manual is not for those drives as stated above, it is for something similar but new-ish.
The picture of his actual machine shows wiring and labeling for analog +-10V control, and so does the first PDF with the machine wiring schematics.

Grotius, thank you for you interest in this subject. 20ms is not bad for a component such as halui, the problem is mainly to do with timing, since it runs in user space its execution time is unpredictable. Now when you connect halui to hal components (realtime components) configuring becomes difficult. When I configure hal logic I rely on experience and intuition, if I encounter an execution problem I correct it by setting he proper execution order of the components. But with halui the execution time is unpredictable. Configuring mix of hal and halui is a pita.
If you have chance have a look at simple logic such as  run/step pause resume logic and you will see that its not easy to configure such simple logic. If the same configuration was done with halui running in realtime that configuration would be much simpler to create and behavior will be predictable and repeatable. 

In nutshell halui running in user space its execution time is unpredictable. 

Since I am not C++ & RTOS programmer. I am hopping that someone from the community with those skills would try convert (probably no the proper word) halui from user space to realtime space. It's probably a lengthy process. I will be more than happy to help with the testing.

Thanks again Ben

In a "switchkins" XYZABC" serial link machine...

If all the joints are defined angular, do I set Max_Velocity or Max_Angular_Velocity under [JOINT#] ?  Or is it sufficient to only set under [TRAJ] ? Same for [TRAJ] do I set Max_Velocity, Max_Angular_Velocity or both?

I'm thinking I need to set the values at the [JOINT#] level to handle the various gear ratios.

What would you recomend?

I have never used clasicladder, but i always use Axis, PlasmaC and QtPlasmaC.
Gathering some stuff to build a mill, so might start using QtDragon or QtPyVCP, no idea when though.

Been 8 days since i got delivery of 410W solar panels, they are still inside the house...

What GUI do you intend to use?
Axis should work, mostly, and there are some made specifically for small screens, like:

You have 1 encoder on Mesa 7i96S and 6 more on Mesa 7i77, so you can use any of those for THCAD.
The issue of it not working might be changed encoder number in hal in the firmware, so use the "show hal configuration" from the "machine" menu to check what number is assigned to Mesa 7i96S encoder, should be 0 or 6.
