PostConfigurator and mom_kin_spindle_axis redefinition

Experimenter

Hi all,

 

I'm creating a post for a machine that uses head angle, Depending on the head, I need to redefine the variable mom_kin_spindle_axis.

I'm doing it before the tool change, and after I reload the kinematics, but rotations and coordinates are wrong. The rotations and coordinates are the same, no matter if I changethis variable or not.

 

How could I reset or rewrite that variable in order to get the right rotations and coordinates?, Do I need any extra step to redefine them.

 

Regards

You might want to check the tcl file for the post to see if something else changes mom_kin_spindle_axis back to the original on you. 

Easy test:

- where you reset it, use "MOM_output_text" to output the current value for the array

- in initial/first move use "MOM_output_text" again fore the current value

- look at the output - is it what you set, or the "original"?

 

If it gets reset, tracking down what does it will be "interesting". 

See what value it has in "Start of path" event - could be you could reset it to your desired value there, after the internal code changes it on you.

 

Note there is also mom_sys_spindle_axis - you may need to set this as well...

Looking in one of my posts, there may be a "mom_spindle_axis" as well

Hello Javi

Ther are some possibilities in PC
-- create an Chain with the right angle head
-- Insert an UDE with the head spindle axis an the offset
you should insert this UDE after Tool Change Event

The issue that I'm facing is that the head device has not a fixed tool orientation, so using mom_isv_ I know that a device is in use and what is the tool axis when a head device is mounted. Then I need to set the mom_kin_spindle_axis array.

 

I've been trying to mimic the same behavior as an UDE and trying to define the variables after the tool change, but with no success, So I must be doing something wrong, but can't find what
