Hal-Histogram

I think any thread that it is associated with has to be a floating point thread,
To load a base thread with a floating point use loadrt motmod ... base_thread_fp=1 (With the ... being what ever else what already on that line in your hal file.)

Hi Todd,
sorry to ask again, but I only have the servo-thread and motmoto is allready loaded.

I am using the axis simulation that is automatically selected when starting linuxcnc.
Can you give me some guidance on how to get a 25ns instead of the 1000ns base thread that I can analyze with the histogram?

Thanks

The line would be something like this. but it could look more like this using ini variables.

Thanks Todd,

Your help is realy appreaciated. However, I am getting an error because motmod is allready loaded. I am still using the axis Simulation.

If there is an easy fix, I would be glad.
However, I'm still learning inuxCNC and that goes beyond my knowledge at the moment. I will go on digging into LinuxCNC and come back.

Until then I will assume that the latency I am getting for the 1000ns thread is similar fo the 25ns thread and go on building my CNC.

Thanks
DomCa

You can't just add the line to a hal file. There is already one there somewhere (probably towards the top of your primary hal file.) After you find your existing line add the bits pertaining to the base thread to it. (has to go before the servo_thread part.)

Make sure that only one HAL file loads motmod, and that it is the first HAL file loaded, and that it only does it once.
