Hi Colin,

Seems to work ok for me.   There is a define to specify which KFLOP persist variables are used to pass information.  Such as:

#define TMP 10 // which spare persist to use to transfer data

Did you include that?  Otherwise I would expect you would get an error.  Post your entire program.  What KMotion Version are you running?

Regards

TK

Hi Colin, I can't see how the file would compile without an error if TMP was not defined.  Did you check if it compiled correctly in the KMotion.exec C Programs Screen? Only one TMP definition is required.  The same TMP persist region is temporarily used for all the various transfers between KFLOP and KMotionCNC. HTH Regards TK From: "Colin Fera colin.fera@...

It will take some time to sort out.  As a workaround you might re-map your axis in standard order.
