G08 Accel/Decel question

[Fighter]

If I press the "EIA Assist" button to display the G-Code the controller (Delta 10) digests, I see G08 and G09 listed.



Does this indicate that they have been parametrically enabled?

I programmed a G08 at the beginning of a part program, and I can't really tell any difference in the axis movements or feed rate indication.

Did I place the G08 correctly?

T33 M6

G08
G0 X1.0115 Y-0.75
G0 Z.050
G21 F10.0 Z-0.005
G21 F30.0 Y-0.7045

Thanks!

Bump - anyone?

I did find a difference in performance when using G08.

I was doing some engraving, which is why I was curious about it in the first place, and noticed that without G08 the characters were not formed correctly at higher feed rates. Makes sense, as that is what G08 would help eliminate.

I ran the same program at the same programmed feed rate with G08 and the characters were perfectly formed, so it is working.

The big difference that I noticed immediately, is that with G08 enabled, the arc moves run at 1/2 the feed rate of the linear moves, whereas without G08 the feed rate is constant throughout both arc and linear moves.

The odd thing is that the actual feed rate displayed on the screen shows that the feed rate is constant, when it is obvious that it is about 1/2 speed through arcs.

Anyone care to take a guess as to why that is?

With slower feed rates there is no difference, but with slower feed rates I find you don't need G08 anyway!
