Hi,

I'm trying to generate a G-Code file from a piece in Solidworks, using Solidcam.

When I simulate the toolpath with Camworks, everything is perfect. But with the generated G-code, that's an other story ... It add some big circles in the toolpath. And I don't know why ...

I'm using Mach3 on my CNC. I used "fanuc" postprocessor.

On the first picture, this is ma part. And the second picture is what it's look like in Mach3.

Does anyone have an idea ???

Thanks ...

Its either a post processor config or a mach3 config problem. Post your part file and gcode and I will take a look.

As you asked !!!


Thanks !!

Ok,
I have downloaded your files and will take a look as soon as I can. I might not post back for a day or two.

Actually,
There is nothing wrong with your gcode, it plots fine in the few fanuc ploters that I tried. It seems your Mach3 doesnot like fanuc format? Maybe it doesnt like the I & J words?

In Mach3 set IJ mode to incremental (General config, IJ mode) or add G91.1 at the start of the code to do this in the program.
You can configure the CAM program to use absolute arc centers instead of incremental.

Thank you for your time !!!

I've just made a test... And It's working well !!:banana::banana:

Thank you very much !!!

I was wondering if you might share your lathe post, I'm having similar issues and would like to get something closer than what I have come up with using the UPG and a Siemens post as a starting point.

Thanks!
