Linearization Tolerance setting

[DavidJackson]

In x3, my linearization tolerance value box is greyed out, im having data starvation problems with my machine with a such fine number (simple trimming machine), any ideas?

 

Cheers for your time / any info -

When you chain lines and arcs you don't have access to the Linearaztion tolerance. You only get access to that when you have chained a spline.

Are you using a DNC/Drip feeding?

 

Some more information is going to be needed to help you out.

Im running the programs from the machines ram, mastercam/post output say a thousand ~0.02 g01 steps to cut say a cicle in a plane that cant be cut with g02/3

 

this machine 99.99% of the time is trimming boxes with huge tolerances that could happily be done with a third this amount of points, and it would reach the right feed rate (and take less time to transfer to the machine at 9600baud)

 

surely there is a simple way to change this somewhere, (ive stared at the help documents/books/google results for a while, but i think that im too close to the problem)

 

cheers for your time,

David Jackson.

 

(one more edit- g64 deaccel at block change is off)

(and another edit- ive played with the value in filter -> tolerance entering huge, small and everything in between with seemingly no change in code?)

Your Post file may be where these arcs are being broken up.

linarc may be the variable used for this.

Use create spline - "curve spline" command to convert your chain of lines & arcs into a spline. This will make the linerization tolerance field available. I just tried it on a circle that I converted to a spline, and the g-code comes out as G01 moves this way.
