I am struggling to post a file from SolidCAM. When a G2 or G3 command are repeated, it doesnt include a G2, or G3 on the following line. KMotionCNC doesnt like this.

I am wondering why it can take a G00 or G01 in this way, but not a G02 or G03. Is there anything I can do in KMotion, or do I have to fix the post processor.

Hi Scott,

The Interpreter needs an "X" or "Y" word or the G3 to be specified. Was that intending to be a full circle? Do you have an option to specify half circles?

Hi Tom,

I am not sure if it was intending full or half, when I manually type G03 or G02 in on the lines it seems to work without the an X or Y word. It is getting tedious manually editing the code.

Hi Scott,

Normally to do a motion at least one axis needs to be commanded to move. Otherwise something such as a blank line could be treated as a repeated move.

But I suppose a full circle is a special exception as i j k at least must be specified.

Here is a patched GCodeInterpreter.dll for V4.35f that should permit it. Copy to the C:\KMotion4.35f\Kmotion\release folder.

Please let us know if it works and if it causes any other issues.

Hello
I am having the same as Scott
I word with nog2 or g3
I gave tried the GCodeInterpreter.dll but Kmotioncnc wont start up with it.
Any help would be appreciated.
Regards Tony

Hi Tony,

Are you running Version 4.35f ?
