I'm a new owner of a wire EDM. Very old control. paper tape and a BTR purchased later. The machine only has G91 mode. All moves relative. Also, G02 and G03 only do one quadrant per command. It takes four commands to do a circle. Format is the same as Fanuc in G91 mode. One quirk, if X Y I or J are zero; the they must be omitted or read exactly X00 Y00 I00 J00 Otherwise, the Gcode looks very much like a mill (just no Z moves). I have example programs I'd like to plot with NCPlot. More importantly, I'm thinking of using Autocad to make a drawing and importing to NCPlot. Then generate the Gcode. Can NCPlot do this? How?

First, before you can generate g-code, you need to have a DXF file. Do you have the DXF file? ![]() . |

| (1) Open NcPlot (latest version) (2) File (3) Import DXF File (select your file) (4) When the DXF file loads a box will pop-up, Select Convert. (5) Convert All You now have g-code. (6) File (7) Save File AS (8) Save as type = Text File (*.txt) You now have a DXF file converted to g-code, saved as .txt file, that should run on most controls, & can be plotted in NcPlot. . |

| Hi Karl, I can't think of a simple way to do this off the top of my head, but I'll look at it some more. The problem, of course, is that the DXF to G-Code converter doesn't allow you to create multi-quadrant arc commands. It will simply output it as one command. It also will output the motion commands as absolute, as you said. These things will take a little time to get working, but I'll start looking at it. Thanks, Scott |

| Is it not possible to break the circle in Autocad at the quadrant lines before the export of the file?
