Hi Wayne,

Thanks for taking the time to post back.

Hi Jim, Here are some thoughts: The Look ahead/Buffer time is only 0.05 seconds. This should normally be at least 1 second. The Max Following error setting of 5000 counts corresponds to ~0.02 inches. This is relatively large so if the axes aren't following the trajectory precisely there wouldn't be ...

Hi Jim,

Hmmm, maybe a lag in the axis positions?

Are the Steppers Closed loop in KFLOP or the Drives?

Please post your Configuration file GCodeConfigCNC.txt, the Initialization C Program, and the GCode and we can look into it.

Hi Wayne, We found a bug determining the Kogna Firmware Version where the Firmware file (\DSP_KOGNA\DSPKOGNA.out) was opened but not closed. This happens whenever a file for Kogna is Compiled or Downloaded to Kogna. This does not occur for KFLOP systems. It seems after an application leaves 512 file...

Hi Wayne,

Thanks for the excellent and complete example.

Yes I'm able to reliably reproduce. It always occurs after 254 M100s which is very suspicious.

Please give us some time to figure it out.

Thanks

Hi Wayne,

Thanks for posting back. If you decide that the code needs to be changed we can help with that.

Good luck.

Hi Wayne, It's not exactly clear how your machine works or why if you have a bed following mode you would want to make corrections to not follow the bed. One option might be to have your bed following mode still use the Z axes by re-assigning the Coordinate Motion System. Do you need corrections in ...

Thank you for your patience and for taking the time to post back.

It’s not clear to me what you are saying. Are you saying the original control just output the same drive command to both motors hoping that the Slave would move the same as the Master without any feedback? You could do that with a C Program. But it seems that wouldn’t work well if there was differen...

No sorry we don’t release that.

If you send us the board we can attempt to reprogram. If that’s the problem then we can return it for shipping cost.
