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..

Thanks,

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..

Thanks,

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

on.

If

it is turned off the machine will ramp up and down for each

entity

that is cut(even in the G64 mode).So if I cut the contour of an
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.

Thanks,
John

John:

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

in

99.9% of

systems.

In mach3 what does angular limit cv mean. There are 2 values

here

and I

am not sure how to define them?

Thanks,
