Hi Tom,

Is there a way to record for analysis the commanded vs actual position of an axis while it is running a gcode program? A data point of each once every second or so would be plenty accurate enough. I am running some high-load programs and I fear there may be following issues.

Any suggestions for generating this type of data would be much appreciated.

Thank you in advance,
David.

Hi David,

Do you have encoders on the axes of interest?

See the \C Programs\CaptureXYMotionPosDest.c example.

Change the for k loop to skip the number of 180us time slices between samples.

Regards
TK

Hi Tom,

Yes there are encoders. Thanks for the file info.
