Hi Eric,

I will set up a part using zero probe and then on the appropriate axis hit the zero button.

What do you mean by this?

Does it involve a C Program?

If so is the C Program configured for Exec/wait/Sync ?

Does the C Program adjust by 0.0055 for the probe size?

Regards

Hi JoeKumanchik,

You should be able to configure an MCode to load the Screen. Then have the C Program Invoke the MCode by sending the PC_COMM_MCODE command to KMotionCNC.

DoPCInt(PC_COMM_MCODE,100); // Invoke M100 Action

Hi Snyggis,

"Destination" is the currently commanded coordinate for the Axis.

"Position" is the actual measured position of the axis. It is only valid if there is a feedback device such as an encoder.

Hi EondeK,

There isn't a command to explicitly save the offsets. But there is a "Save Always" option on the Edit Fixture Dialog that will automatically save the offsets to disk no matter how they are changed. Does this work for you?

Hi EondeK, I'm sorry for missing this post and misleading you. You are correct the PC_COMM_SET_X command always changes the G92 offset. The Fixture Offsets are saved in the GCode Vars and can be modified there. There is a SetFixtureZ.c example of how to do this. I've also pasted it below. #include "...

Hi EondeK, DoPCFloat(PC_COMM_SET_X,0.0); Should perform the same operation as the "Set" button on the main KMotionCNC Screen. The "Set" button on the KMotionCNC Screen can be configured to either change the current fixture offset or the global G92 offsets. Which do you have KMotionCNC configured to ...

Hi SL,

It’s not normally required but you are correct it can be used to reset your electronics or you can GND the pin to force a reset.

Hi Troy,

No we haven’t added distance to go. It would be somewhat difficult because of the look ahead, buffering, and combining and filtering of blocks.

Either forum is fine. There might be more help and exposure at cnczone.

Hi Jon, chan[Z].Position=( ... setting to 1" with math... ); Which I think is the "offending" call that is actually re-setting Machine Z to 1". Is that indeed what that does? Yes And then, as your first link / thread suggests: DoPCFloat( ...also set to 1" using math... ); Which it sounds like only r...

Hi Jon,

Yes that is changing the Machine Coordinate Position.

You might read this Thread on how to use the "Set DRO" function.

I don't fully understand your process but you can configure KMotionCNC to modify Fixture or G92 offsets. See Here.
