Hello, there's a piece of programme developed  in the following program Visuall Mill.

The program will be launched by Mach3.
In this program every line will be in progress in series from (X14.6644 Z-0.0033 A152.683 F350.) to (X15.9640 Z-0.0582 A102.346) … the question is if it's possibleto shorten the number of lines if the original coordinates and the end coordinates are known. For example with the help of interpolation if it's possible in Mach3. If it's not what options should be changed in Visual Mill?

If it's a straight line the code could be more concise, but is it?
You don't say

Run this code and see if the results are the same.

I gave you only a piece of code. The programme itself has a large data size. If I follow your instructions, it will take me too long to edit it and correcting mistakes after that.. Is it possible to customize mach3 that the controller itself run the program with line skipping? And if it's possible what attributes should be run to lounch the generation of post processing in visual mill?

it is not a straight line but a spiral, length 16 mm ..

Nothing you can do in Mach3 to skip code.
You need to ask Mecsoft if there's any way to get fewer lines of code from Visual Mill.

Thank you good man)
