VTB USER GUIDE

Char 0 Command not written in the buffer (buffer full)

1 Command written in the buffer

Notes

Moveto is usually used to interpolate more than 2 axes. The speed vector is distributed on all axes to be interpolated.

When mode=2 it is calculated the presence of a multidimensional edge according to the values in sgl3d. When mode=2

the test of edge is made only on the axis of the working plane and according to the value in sglp. If the comand isn't

written in the BUFFER, we have to wait and repeat otherwise it will be lost.
