Dxf2gcode question...?
Does anyone here know anything about dxf2gcode? There appears to be no help or instructions on the web - the wiki page just lists the headings of the parameters without specifying what they do.
In particular, I am having problems with the Z axis. The generated G code makes the Z axis go up and down like a yo-yo. There are several parameters in the set-up:
1 - Retraction Co-ordinate
2 - Safety Margin
3 - Work-piece origin Co-ordinate
4 - Slice Depth
5 - Final Mill depth
I guess that these refer to
1 - Height that the tool can move at
2 - ?
3 - height of top of work-piece
4 - depth for each slice
5 - maximum depth that tool should go.
But when I fill these in with sensible figures, the Z axis seems to rise and fall by varying amounts which seem to depend on a calculation using these figures. I am doing a simple 2-D cut, I simply want the tool to retract to -10 for movement and drop to -14 for cutting (absolute). What should I fill in to achieve this?

Haven't used it personally and as you say, doesn't seem to be a lot of information for this.
There is a user guide at: https://sourceforge.net/p/dxf2gcode/...e%20DXF2GCODE/
which also has a link to a user forum.
If your intent is to read DXF files and generate GCode, there are other options.
A lot of folks use Fusion 360, vCarve [Pro] and there are others:
Have a look at some of these:
SimplyCam: MR-Soft Nc Software Tools
GrblGru: The Author does not have a web site but the software package is very interesting: https://www.dropbox.com/s/278a8a5uu9...anual.pdf?dl=0
A few samples of Linux tools: LinuxCNC Documentation Wiki: Simple LinuxCNC G-Code Generators
Is there something specific you are trying to do?

I simply edit the g code in text file. Do a find and replace for the z position.

Re: Dxf2gcode question...?
I must admit to looking at Dxf2gcode some years ago and I thought it was great to be able to take the shape I wanted,offset it by a cutter radius and then tell the program to produce the Gcode for the shape that resulted.At the time I didn't have a home machine.These days I do and I use Freecad to model my parts and then use the Path workbench to generate the code.It works every time and if I change anything,it regenerates the toolpath almost instantly.
