G-Code, CAD, and CAM discussions / Autocad to g-code measurement problem
« on: November 20, 2012, 01:48:02 AM »
Hi, I am using autocad 2009, Lazycam version 3.00.2 and MACH 3 R3.043
I can export file from autocad to lazycam.
And then can post code to mach 3.
Problem is when doing these I can't define exactly what will be the drawing size.
Suppose I want a 6 inch x 10 inch nameplate to cut.
In autocad I can define the paper size and hence the drawing size. When opening a new file in lazy cam It shows dialogue for project size, which have no units. Scale drawing in lazycam is actually unit conversion as I understand inch-->mm and mm-->inch.
Also can change the scale (x,y,z scale unit change) in mach 3. And how to change table size in mach 3?
My cnc machine is cnc 3040 commonly sold on ebay. When command G1 X10 F200 it goes exactly 10mm from mach 3.
