Save your project and post it here with ncam.ngc and the file you want to open

I will add in for the next release

No. It is a limit I set. I may change it if needed.

You can override ALL values where you have the option to "Change for g-code" in the context menu when right click.
When changed, you have the option to revert to original type

Ok guys, I had this problem for the first time this morning.

I am trying to mill a counter-bore for a 6mm screw with a ¼" end mill.
If I select a ¼" screw it is ok as well as a 7mm screw. Or if I select a smaller end mill.

I will find a way to prevent this.
However, I will be away for the next 10 days and I am not sure I can do it before I go.

Regards
Fern

P.S. Rene, can you tell me what you are doing when this happens ?

I try to change the cutting depth in NativeCAM but apparently this is not possible
the default value is 0,508
and if i change it for example to 0,270
It changes automatically to 2,54

How can I fix this?

See attached pictures

This was not directly related to NativeCAM, and has been fixed:
github.com/LinuxCNC/linuxcnc/issues/308

re: "unable to open file<>"
I encountered same with linuxcnc 2.7.10 when adding a rectangle in ncam
I did not have errors adding circle
The linuxcnc team issued linuxcnc 2.7.11 on 28july2017,
I installed this version and retried adding a rect to a project...
the error is gone ( as far as i have tested )
--
more testing shows a well defined error in 2.7.11

IF the rectangle is added out of sequence
meaning, while 'workpiece' is highlighted,or as soon as a new project is opened

THEN the error occurs "named parameter #<_tool_usage> not defined"

mark this up to operator error
thanks

Hi,

Follow the right sequence

• Workpiece and Tool Change (order does not matter)
• Shapes

If you inserted a shape before Tool Change, just move that shape with the Down button or hold down Ctrl key while pressing down arrow

Hi Fern,

I just recently upgraded NativeCAM, and noticed this limit. When I wrote the thread-milling module, one of the first things I used it for was thread-milling Hastelloy c276, which I would most definitely not want to cut at more than 0.5mm a pass. I'm just curious why you set this minimum value in the configuration?
