Hi!

I have unexpected reset to 0.0 on all 6 coordinates when use
CCoordMotion::StraightFeed.

I do:

G0 X500 Y500 C0

Then - PC program with

sprintf(chCmdMove, "%s%f", "Move5=", fAngle*(180.0/PI)*p->CountsPerInchC);
CM->DoKMotionCmd(chCmdMove, true);

Now all great.

But when I do

int nDrillResponse =
CM->StraightFeed
(
0.5,
fTargetXMillimeters/25.4, fTargetYMillimeters/25.4, fDestZMillimeters/25.4,
fDestAMillimeters/25.4, fDestBMillimeters/25.4, fDestCDegrees,
0, 0
);

all the coordinates falls to 0.0,
and only then - moves to the task values.

Help, please...

Now I see -
int CCoordMotion::GetDestination(int axis, double *d)
returns me wrong values.

Is it function gets the current position on axis?

Hi Yan,

The Coordinated Motion Library Current Positions need to be synchronized to your current starting position.   Sorry our example should have included this.  Try adding:

    int result = CM->ReadCurAbsPosition(&CM->current_x,&CM->current_y,&CM->current_z,
                                                          &CM->current_a,&CM->current_b,&CM->current_c,true);
 
Add this before the call to the first StraightFeed().

Regards
TK

Hi Yan,

This returns the current commanded destination, not the measured encoder position.  It should return the same value that is currently on the KMotion Axis Screen Destination for the Axis.
