using lazycam makes wrong or unfinished pieces
It does what it is told to do. Same goes for any other program. Read the manual.
Same goes for any other CAM program. No program can read the users mind on how they intend on doing something.
Let me clarify........my bride of many years may be able figure me out.  ;)

Got that right Hood,
Gave up after she told me that "it took her so many years to get me just like she wanted me and now she's not sure who I am" ???
Ya just got to love em........... :-* Men are from Mars and Females are from Venus :P
Easy to get confused at times ;) That's why a shot and a beer can put things back into perspective.
Burp  ;D

Never used it but from a quick look it appears that LazyCAM posts either inc IJ OR abs IJ depending on how you set it on the Post Gcode option screen. Either way it EXPLICITLY posts a G90.1 or a G91.1 in the code preamble. So unless I'm missing something Mach can NOT get the mode wrong regardless of what you might have set previously in Config/General Config. Mach simply switches mode according to what is POSTED. Although a mis-match of IJ mode WILL cause this error I don't see how this can be the case in this instance. The ONLY time the operator has to make sure Mach and CAM modes match is when the CAM DOESN'T explicitly post the mode. There are other reasons why you might get the error in your title and I suspect that's the case here.

Thank you Rich for youre very intelligent response,

I'll read it, but after some research, I think that finally, DXF's files made on Solidworks are quite not compatible with lazycam.


Stirling, thank you for you response. I had this problem only when I was using Import dxf's file's option on Mach3, now with lazycam, there is no radius problem, excepted a wrong or unfinished piece.


Can I post one of my dxf files then you try to open it on lazycam ?

Thank's

Ps : there is a DXF attached, after using lazycam, I get this quite wrong g-code :

Hi Armenias

Your DXF works fine in LazyCAM and it produces good code on my system. I'm thinking you're running an unlicenced demo version which is restricted to the number of lines it'll handle. Hence your gcode is not wrong - it's just not complete.

In fact I use a demo version, but I didn't know that demo version was restricting the number of lines. If it's true, I buy it tonight ..

Thank's a lot Ian

Every thing works perfectly ! Except a scale problem on mach3 (distance divided per 2), but i'll find the solution..


Thank you everybody !

hello all.  I know this is an old thread but i am getting this Radius error and changing the IJ setting from absolute to incremental in Mach 3 is not solving it.  I have been stuck with this for months and not able to test out my CNC machine.  Any help would be GREATLY appreciated.  Below is the code i tried, but i am getting it on multiple codes that i have tried.  This is just a simple hexagon i created to test the machine.
