LazyTurn / DXF Drawings

« on: May 16, 2011, 05:02:40 AM »

Hi there,

I do have "converted" my Syil X4Super into a CNC lathe by adding 80mm chuck with an SK40 cone and putting the toolholder on the table.
Mach3Turn runs (I have not yet understood everything but the first parts are ready). The path-generation is done with LazyTurn wich works mostly fine.

My question: Which programm do you use for the generation of the DXF files? I do all my construstion work with the 3D CAD "Alibre" and I found it impossible to generate these special kind of DXF drawings for LazyTurn.

Do you have any suggestions for an inexpensive programm were I can draw the profiles I need?

Any suggestions would be appreciated!

Yours

Gerd

G-Code, CAD, and CAM discussions / Tool change with length-compensation

« on: September 15, 2010, 05:44:39 AM »

Hi all,

I´d like to do a tool-change during my programm, but it doesn´t work. Any help would be great. I use the current version of Mach3

Workpiece height is set to +151mm; Tool-length for #4 is set to -229mm; Tool-length for #9 is set to -192mm

From my point of knowledge the following programm should place tool #9 on the surface of the workpiece, ask for tool #4 and place than tool #4 on the surface of the piece.

It doesn´t work, I have tried to switch tool-offsets on and off, etc.
Can anybody give me help please?
