New guy
« on: October 09, 2015, 09:01:55 PM »
I have bought a small used cnc router. Just got Mach 3 demo loaded. I tried to load lazy cam and keep getting a win32 cabinet self-extracting screen, application error. I have AutoCAD and would like to import into mach 3 as DXF. at this point I'm wondering if I should try to get Lazy cam loaded or get a new cam program. Like I said I'm new to this, but not new to milling or AutoCAD. Just new to the conversion to gcode part. Any suggestion or words of wisdom would be appreciated.

Thanks,

Bill

I am not certain what is causing the problem with loading LazyCam that you are describing - it can be loaded as part of the Mach3 install and is usually quite painless. Perhaps un-install and re-install Mach3 including LazyCam and see if that cures the problem.

In the meantime and if it's any help, there are others using AutoCAD together with AutoLISP to create the necessary Gcode for Mach3.

Thanks for the info. I tried to uninstall lazy cam and reinstall. I will try the mach 3 too! I used lisp files about 20 years ago.
Thanks again,
Bill

If you want to create g-code from within AutoCAD, try  my VBA macro.

Much easier then messing around with Autolisp.

Thanks for the replies. I am using AutoCAD R14, It appears it may be too old to run the software you have suggested. I will start looking for a newer version of AutoCAD.

Honestly, do your drawing in autocad if that is the cad pckage you are most comfortable with (dassault draftsight is free (for personal use)) compatible software package),  then open your dxf in sheetcam and generate your gcode there, after setting up your machine and defining a few tools (really simple).

Have a look on YouTube and search you,for sheetcam, there are a huge number of easy to follow detailed well presented tutorials.

Alternative 3d software (if you need 2.5d too) would be onshape, which is again free... But I must admit not sure about the export file format (one thing to watch... Don't draw something and then realise you can't do anything with it (like I did with emachineshop....))

Yeah, you're probably better off getting a CAM program to import your AutoCAD drawings, like Sheetcam or Cut2D.

Or, try the free Autodesk Fusion 360, which does both CAD and CAM.
