Lazycam lead in: How to change code??

[skipper]

Hi All,
I took a dxf file from cnczone and in autocad reduced the size to half. I exported as a new dxf into lazycam. I created the code but has a long lead in (see pic, I think that is the proper term). If I zero my rockcliffe router to the center of the y table, when I hit start, the axis move to the beginning of the lead in which greater than my table. How to I reduce it or get the tool to start in the center or very edge of the part? It always seems to have to start from far from the part and then have to make its way to the part. Is there code I can use to always have the tool start in the same place on the table??

You need to set your origin in LazyCAM. The g-code coordinates are where the part is. I don't use LazyCAM, but here's a link to the manual.

Or, just edit the g-code If it's only the single file you have a problem with.

It should be a X & Y move. Just edit only the Y-axis axis in the g-code line (from looking at your screenshot).

Switcher, I don't think it's a g-code move. It is, but you can't just edit it, because it's moving from the current tool position to the first line of g-code.

Hello, my lazycam import a dxf file from sw and post a g-code, my mach3 used this g-code to cut the part, which is big than the design size? what should I do?
thanks

Make sure the scale of the .dxf export is 1:1, and verify that the resulting .dxf is the correct size.
