In a tab I think as my right hand pane of the axis display is full up with tallies and displays for a tach, spindle direction and several other utilities. OTOH, if that right hand pane could be tabbed too, that would be useful. I think I won't be needing those buttons and tallies while ncam is running. Only after ncam has done its thing.

Your panel is a PYVCP and can not be in a tab, it needs to be converted to a gladevcp.

I just did, again. I'll consider that, and glade-gtk2, when it Just Works on an uptodate wheezy 32 bit install.
Or on an r-pi3 running Jessie, or a rock64 running stretch.

Yes, its faster, but there is always the "when it works" caveat.

So far, that quest for both the capability and power fail to next power fail stability has been a miserable failure, and bug submissions (which I've done, years ago now) are canceled with won't fix, not supported anymore so use gtk3 stuff, failing to admit that gtk3 is still suffering from the whole concept being thrown under the bus. It still, what, 6-7 years later, has only 10% of the capabilities glade-gtk2 had. pyvcp has its own problems with wasted screen real estate, but generally it just works, every time.

I'll try it, but I'll have backups too so I can back away the third time it doesn't just work.

Thanks & Cheers, Gene1934

1. Rename your ini file GO704fast.ini.bak
2. Copy included file to /home/gene/linuxcnc/configs/GO704fast/
3. Start LinuxCNC normally with this ini file

Best regards
Fern

Thanks FernV

I'll give this one a try tomorrow. The ncam -i install seems to have worked ok too,

Now I am looking for an fft histogram chart maker so I can define the best focus distance of this camera. Looks to be something in the 4cm range while scanning a small upc bar code. An fft histogram should nail that down pretty closely.

Cheers, Gene1934

Sorry Fern. just got back to hobby after crazy time at work.

Truetype-tracer is 4.1-2 version
ncam is 0.1.14b version

Below is output that ncam give during start - not a lot of warnings

Also, folks - facing strange issue.

I am trying to execute g-code file on other machine where ncam is not installed. I am loading it into LCNC and getting error - "Unable to open file <select>"
LCNC complains on this line -

o<select> CALL [31] [0] [0.000000] [0.000000 - #<wp_length> / 2] [0.000000 - #<wp_length>]

it is some sort of external subprogram or what exactly?

NativeCAM is designed as a package and all ngc files included in
[RS274NGC]SUBROUTINE_PATH = ncam/my-stuff:ncam/lib/mill:ncam/lib/utilities
are needed.

It is a library and your other machine must have this in it's ini file as well and must have access at those files.
ncam.ngc depends on them

Thanks Fern,
here is enhancement feature if you'd like: to generate completely portable g-code which can be executed on any machine

FYI, you can use ncam generated code on any machine running lcnc as long as [RS274NGC]SUBROUTINE_PATH is pointing to directories containing the needed (.ngc) files. Just copy them to your other machine.

Most of them will be updated in the next release and will have to be copied again.

Hi,
i like your Nativecam tool very much. But i see in some videos a tool probing routine like tool diameter probing. How can i activate this functions ?

Thanks
