HI,

The manual says "In Format 2 the H word will only pick up the tool length offset. It is also used for Tool timers selection" and the gcode looks like this:

T1 M6
G90 S7500 M3
G54 X-2.305 Y-1.095
H1 Z1.06 D1
M8

T5 M6
G90 S3124 M3
G54 X4.27 Y.5599
H5 Z1.06 D5
M8

Aren't the tool offsets set with the UT command? Why do I need an H word then? What do the "Z1.06" and "D(tool number)" do?

Thanks!!
