Hi Scott,

Could you be more specific what you are doing?  What exactly are you doing in the C Program?   What parameters in the .set file are you referring to?  What are your GCode Offsets?  Are you setting Machine Coordinates to Zero?

I am setting to use all 6 axis on a CNC wood router. I am using a homing program to touch off tools. In the "C" program when I "Zero(axis)" it takes the file stored in the ".set" file and makes it the current position on KmotionCNC.

My problem is that this only functions for X,Y,and Z. I dont see values in the set file for A, B, or C. Is there another way to do this? Can the set file be altered to have zero positions for the other axis as well?

Thanks,

Scott

Hi Scott,

I think I understand.  You are using the G92 Axis Offset to set the origin for your vice.

If you open the edit fixture offsets you should see your xyz offset on the bottom for G92 offsets.  Do you see this?

Why not put the xyzabc offsets there and remove forcing them in the .set file?

Tom,

I use the following code to zero an axis:

    Jog(2,100);             // jog slowly positive

    while (!ReadBit(10)) ;  // loop until IO bit goes high

    Jog(2,0); // stop

    while (!CheckDone(2)) ; // loop until motion completes 

    DisableAxis(2); // disable the axis

    Zero(2); // Zero the position

    EnableAxis(2); // re-enable the ServoTick

    Move(2,-1000.0); // move some amount inside the limits

    while (!CheckDone(2)) ; // loop until motion completes 

Lets say that channel 2 is the "X" axis. I have measured the distance between the home switch and the zero on my vice to be 4.458 inches. I put that value in the .set file as shown:

axis_offset_x 4.458 any real number

Now when I home the axis it sets the work coordinates so that x is set to zero. The set file only has an option to do this for 3 axis:

axis_offset_x 0.0 any real number

axis_offset_y 0.0 any real number

axis_offset_z 0.0 any real number

I would like to be able to home my machine, and be able to input an offset for X, Y, Z, A, B, and C. Does this make sense?
