Subject: CCoordMotion Singleton ?
In an attempt to provide flexibility, I implemented two separate CoordMotion instances int the KM_Controller.cs class.


The thought was to use the interpreter for.... interpreting and have the ability to use a separate CoordMotion class for aux motion(tool changes, etc...)

However I get an exception when trying to use the two consecutively.


Is CoordMotion a Singleton on the board so I can only have one per Kflop?

Hello,

Hmmm.... I suspect something else may be going on. I can manipulate the KM_Controller.CoordMotion instance - say like calling Abort() then ClearAbort().

I can then Interpret a file with no issues (KM_Controller.Interpreter has it's own instance of CoordMotion).

It is not until I try to call a direct motion call on the KM_Controller.CoordMotion instance (StraightTraverse)that I run into the Object not set an instance of an object...blah blah blah.

Is it possible the TP is being shared and causing an issue?

Thank you,
Brad Murry

Hi Brad,
 
I'm not sure.  But yes the TrajectoryPlanner variables and buffers are global so that would be a problem.  I'm thinking two instances is a bad idea.  There is a lot of internal state for example how much is downloaded to the KFLOP coordinated motion buffer or whether KFLOP has been told to execute, or the current axis positions, etc... that would get messed up.  But then on the other hand I believe I have ran multiple KMotionCNC applications simultaneously and as long as one or the other is always "idle" it seems to work ok.  But I can't justify putting a lot of effort into this as I don't know of anyone really needing it yet.
 
Regards
TK

FYI

Not sure what was happening before, but after a new boot this afternoon I was able to do some CoordMotion calls followed by to file interpretations and the another round of direct CoorMotion calls.

Not sure why I received those errors before, but likely a result of many days of up time on my heavily used dev machine.


Looks like we are in the clear for mixed interpreter/coordmotion usage.
