DRO clear

[ltran2000]

Hi Tom
Please help, If I use the set button to put some number to DRO like #3
and after I press INIT(reset) number 3 still there even i use the code:
Zero(0,0); ch0->Position=0; EnableAxisDest(0,0); the #3 still there unless I use ZERO button to clear the DRO. I need to assign a TOUCH-PLATE script to a button but#3 still there in the DRO. what code used to clear DRO. Ltran

Hi LTran,

I'm not sure I fully understand. But Yes the "Set" button on basically introduces an G92 offset.

If you assign a C program to your "Touch Plate" button. After the C program does the probe operation it could then issue a KFLOP -> PC command to Set the DRO to zero or some other value. See the example:

DoPCFloat(PC_COMM_SET_X,0.0);
DoPCFloat(PC_COMM_SET_Y,0.0);
DoPCFloat(PC_COMM_SET_Z,1.25);

in the

KFLOPtoPCCmdExamples.c

Thanks Tom, I have another question, after I start my machine and
homing so xyz=0, and move to the material need to cut and I assigned
these code to a button to zero XY :

DisableAxis(0); // disable the axis
while (!CheckDone(0)) ; // wait till we are stopped
DisableAxis(1); // disable the axis
while (!CheckDone(1)) ; // wait till we are stopped
EnableAxisDest(0,0);
EnableAxisDest(1,0);


and while it cut and some error happen, I want it move back to material xy zero using these code:
Move(0,0); Move(1,0);
but it keep going back to cordinate zero(homing zero) not
material xy=0 , hope you understand, Thanks

Hi Ltran,

If I understand you correctly I would think that would work.

This code should zero the Machine Coordinates (although the "while" waits are not really needed) :

DisableAxis(0); // disable the axis
while (!CheckDone(0)) ; // wait till we are stopped
DisableAxis(1); // disable the axis
while (!CheckDone(1)) ; // wait till we are stopped
EnableAxisDest(0,0);
EnableAxisDest(1,0);

You could verify this by displaying Machine Coord in KMotionCNC or looking at the Axis Screen in KMotion.exe

Then

Move(0,0);
Move(1,0);

Should move to Machine Coord 0,0


But I thought in your earlier post it seemed you were using the Set Button to set an GCode G92 offset to set/zero the DROs. In this case Machine 0,0 would remain at the original Home location.

These codes do move back to coordinate zero, I am confusing with something else, thanks Tom
