Hi Graham,
I am just testing out my probe.
I am not using any offsets and G90.
If I am at say x4 y4 and program a g31 x6 f15 the table moves in the negative direction, I am assuming it should move in the positive direction from 4 to 6. Same thing occurs in the Y.
The Z responds the way I think it should.
I am testing out a new firmware and was just making sure that there was not a know bug in the recent releases of Mach3.
Since Ray L. has got the knee working for tool length compensation and I have seen some nice ways to automatically find the center of a hole and so forth, I thought it was high time I got my probe working.
