I have used the machine both ways and it runs better with it on. If

6"X12" elipse at 600 inches per minute the machine will still ramp up
and down for each of the entities that make up the elipse. I would
like the machine to ramp up at the first entity and down at the last
entity. If I use G64 and set the angular limit to 85 then it will cut
smooth. The machine setup 1909.8593171 steps per inch and I use the
campbell board with G201 geckos as drives. Any help would be much
appreciated.

Leave it off unless you have severe rounding. It is unused in

99.9% of

systems.

Hello Art:

What about the other value that is listed just below the angular
limit? I am not sure of its function. It says cv feedrate in front of
it and the value is set to +1.00? If I do most cutting at 250 inches
per minute should I set this value at 250 inches per minute.

Thanks,
John

Hi John:

Hmm, as I recall its function it shoudl make it worse. The effect

is

telling the system to not CV any line which
exceeds that setting. So if its set to 85, it will do exact sop is

the angle

betwen lines is greater than 85 degrees.
(But when its off, all lines shoudl be CV'ed.. Ill take a look at

the code,

but in the end, if its better on, then leave it on
, it wont hurt any any rate..

Hello Art:

Could the lookahead be set to low I have it at 60. I am running a
750mhz cpu and 25khz in mach3. And should I use enhanced pulsing.

Thanks,
John

Hi John:

Thats CV feedrate. It tells the ocntroller to not begin blending

in the

next move, until the feedrate falls below that value.
In your case, a ballpark woudl be around 40..

Art:

Well I have almost got it. I was reading a thread (smooth cutting
issue) And followed the advice you gave them and now it cuts smooth
except if I increase or decrease the feed rate using the on screen
buttons. For instance if I cut an elipse at the programed rate of 300
inches per minute it will cut great. If I run the feed rate up or
down on the fly it will instantly cut like it is in exact stop mode.
If I edit the program to a feed of 100 inches per minute and reload
the gcode. It will then run smooth at the programed rate,but If I run
the feed rate up or down on the fly it will instantly cut like it is
in exact stop mode. I am not sure what else I have setup wrong. I
hope you can help.

Thanks
John

Hi John:

Yes, almost everyojne shoudl be using enhanced pulsing, I know of

only two

for whom it creates trouble, it smooths things out for everyone

else. 60 as

a look ahead is fine. Higher wont help.
