I found this diving in the documentation:
"for trivial kinematics, X is always joint 0, A is always joint 3, and U is always joint 6"
What do you think about Rod, this could be the mistake?

Yes, I think equal, in fact one of the threads I have followed was yours, with a plasma Torch, I compared the Ini and Hal and I think I have it equal, saving the obvious differences.

That does not sound right in a joint axis world. I think its a typo.
I was running on joint 4 of a 7i76e (Version 2.8)
I found my A xis Config dated back to 2017. hal and Ini files are attached. There needs to be a change to the newer multispindle format for this to load.

My apologies dgarrett, you're absolutely right, I'm sorry.
Rod, thank you very much for attaching the files, I will compare them to see what I have different, thanks.
Hello Phill, thanks a lot for this info, I dont ser nothing similar ok my display .

The jamming of the linear axes in continuous jogging seems to be solved by reducing the speed, I will have to assume limitations of working with motors without pulleys.
Regarding the A axis (at the moment it is only a stepper for tests) I have observed several things:
1-If I work with linear speeds in the Preview window it is the tool that rotates.
2-If I work with angular speeds the tool remains static but in the coordinates if it acts as it should (rotations from 0 to 360 degrees and so on) from what I understand it would be correct.
Is an advance!! although in neither case do I get movement in the engine. On the other hand, I do not know if it will have something to do, but for giving the maximum possible data, when making a new configuration, arriving at the A axis, when I give test / tune axis an error window appears, attached copied text of the error.

Finally I was able to install the DQ860MA drivers but the blocking problems persist. Both continuously jogging and using MDI commands or running a program suddenly the motors are randomly blocked, with its catastrophic consequences .
From my ignorance and by elimination I think there can be two things:
1-some type of PC failure
2-section of insufficient cable (I am using 4-wire USB cable)
Since the rest of the components I understand that they are of a respectable quality, MESA cards and the mentioned drivers.
I would appreciate any help, I'm starting to despair.

Even high-power USB cable tends to have smaller wires for data (24AWG for power, 28AWG for data) and 28AWG is only really usable to 0.5A.

I have wired from the drivers to the stepper with section 1.5 and the problem persists.
