Change acceleration on the fly?

Category: General LinuxCNC Questions

Hello,
I have created HAL configuration as explained by mjohnston, with a single pushbutton. The functionality is that when I push and hold the button, the acceleration of all axes must be set to 10% of their actual values. However, my application is different. I'm not using M-Codes.

I found that this change of acceleration works for me, but it has a very deviated output. The button press effect occurs after a large lag in time, and the amount of time varies for different programs.

More digging with debugging tools revealed that the trajectory planner has buffered lines. When I press the button, the acceleration change works after the previous buffered lines are executed. Also, the button release event has this lag, as well.

So, my question is: Is there any way to make this acceleration change happen immediately upon button press or release? Or, is there any way to change the buffer size in the trajectory planner?

I am available if you need any more information on this.

motion.misc-error-NN does not work

Category: HAL

  Hello Aciera,

thanks for your reply.
I see the difference. In my machine the motion.misc-error-00 i see only as signal, not as pin like in your picture.
It is not in my pin-list and i see in the documentation that it is not standard-list (linuxcnc.org/docs/stable/html/config/core-components.html).

In which way can i get this pin? (Sorry, it's my first machine with LinuxCNC).

Thanks
Michael

Can We use tool.tbl data as position of tool, or its only use for setting tool offset. And yess then how?
ATC possible direcly using tool.tbl ?

Aside from the schematics, I have a question. When you retrofit the machine, do you remember what locking mechanism was present to lock the spindle to each tool after the tool is changed? Any sort of clutch or clamp mechanism (hydraulic/electric/mechanic, pneumatic)?
