Variable speed

[xPhilippeRoux]

Hi,

I would like to export a module that does not contain any pre-defined speed but a variable that I choose instead.

In RAPID language I have : MoveL [[111.11637,198.629959,496.876908],[0,0,1,0],[0,0,0,0],[9E9,9E9,9E9,9E9,9E9,9E9]], [250,572.957795,5000,1000], [False,1,0,1,0,1,0], NullTool \WObj:=Root; And I want : MoveL [[111.11637,198.629959,496.876908],[0,0,1,0],[0,0,0,0],[9E9,9E9,9E9,9E9,9E9,9E9]], mySpeed, [False,1,0,1,0,1,0], NullTool \WObj:=Root;

See screenshots attached :

Thanks.

You should choose PreDeclaration instead of Inline and use a defined speed.

We actually use the defined speed in Inline declaration, but it is not written as a variable.

Thanks.

In that case am I able to choose which variables to predeclare ?

I don't need to assign a name to all the targets, and I don't want to declare a speeddata that is already declared in my robot task (I just want to use it in the move instructions).

[tristangobin]

So, the actual behavior is either you predeclare everything or you have inline declaration. You can't choose which variable should be predeclare. I will mark this as Enhancement.

It means that you are using a Task with speeds that are already set, but not by HAL. This raise a question, if you are using speeds that are not declare by HAL, how can we simulate toolpath with correct speed?

It would be nice to have a case study to understand exactly what is needed here and the reason behind this request.

[tristangobin]

So, I think that it involves several things that are beyond the use of a variable in inline declaration. We should be able to mark a setting like a speed as System variable, something that is imported from a remote controller. However, we would need to match the Aliases and replace. We do not have the capacity in the public version to import data from a controller. And also, this is only feasible on controller that allows such feature, which is not the case for all.

I will leave this open and we will have a discussion internally on how we can propose something.

Let me know your thoughts. This discussion can be pursued in a more private thread if this project involves intellectual properties.

Thanks for this explanation @tristangobin.

My speeds are actually calculated inside my Grasshopper file, but not via a HAL component.

I would be happy to discuss this point along with discussion #94 about multiple toolpathes export. This is the main global subject. Shall we plan this meeting with you and @sebandraos ?
