NativeCAM is Features renamed

Yes you're right, I understand, but I tried to change the preamble and postamble adding the %, but I got a gcode syntax error. I need to replace M2 for %, and add % to the same begining of the gcode

Usually "%" is not needed, unless you have a very specific reason to add it, which I do not know

Fern I solved my tool change issue by deleting "M600" from the pre-amble and setting the lenght compensation to "none". Could you please tell me which file I have to modify to delete M2 from the Gcode? Sorry for bothering you again mate.
Thank you!

This is what I was going to recommend

Unfortunately, it is hard coded. I do not think adding "%" to post-amble in the preferences would solve the problem ? That field is blank by default.
I will add an option in the preferences that would either end the file with M2 or "%"
If using "%", you would have to be sure the pre-amble is right.

If you can not wait for the update and simply want to remove M2, then
$ sudo gedit /usr/share/linuxcnc/aux_gladevcp/ncam.py
goto line 3540 and remove M2
save the file
If you mess, reinstalling the package would restore it

I usually work with multiple offsets also within one Gcode (maybe better install the master 2.8 that supports G52, dont know) and have M2 in the end of the file is very annoying for me. Adding % in the post-amble preferences does not solve the problem because anyway M2 remains at the end of the file and result a syntax error.
If you add the possibility to choose between M2 and % (and in the begining of the file) will be great for my purposes avoiding to edit the final Gcode every time I save it. At this time I think better for me to edit ncam.py
Thank you very much for your help. Your kindness and selflessness has no limits. Thank you so much.
Keep up your great work!

def create_defaults(self):
self.default = _('%\n')
self.default += _('(*** GCode generated by NativeCAM for LinuxCNC ***)\n\n')
self.default += _('(*.ngc files are best viewed with Syntax Highlighting)\n')

self.default += '30840-new-syntax-highlighting-for-gedit)\n'
self.default += '(or github.com/FernV/Gcode-highlight-for-Kate)\n\n'

return self.pref.default + gcode_def + \
_("(end sub definitions)\n\n") + gcode + self.pref.ngc_post_amble + '\n%\n'

I modified the 3540 line by replacing M2 for % and added the string % to the beginning of the g code file. Now I have the file wrapping by % and all runs ok. Good job Fern!
Thank you again!

Hi Floris,

On next update, you will have to edit Preferences and check this box

Hi Fern, I'm trying to engrave some text and maybe I miss some dependences or, should I make some setting before run the text engraving function? The same issue I have with the text engraving example. Could you take a look please?



Floris

HI Floris,

I can not find the meaning of this 255 code.
Check that truetype-tracer package is installed and also the font you want to use.
truetype-tracer should usually be installed with LinuxCNC

I checked the example and it seems it was not updated with the latest changes,
you could have an error because it can not do a G1 with a feed of 0. This is just for the example.

Fern

P.S. A simple reminder that if you always want "Tool length compensation " to be "No",
you can set and save all "Tool Change" values as custom default using

Thanks Fern for your tip, I have saved my defaults values and then hid coolant compensation and tool length functions.
The installation of true-type tracer solved my problem with the engraving fonts, but in the example of the project the error of G1 without Feedrate persists.

It would be nice to add a 45 and 90 degree hatch option to the engraving function.
Are you planning to implement tool wear compensation, maybe G41.1 D#; G42.1 D# for simplicity? I could not live without dynamic compensation.
Imho a calculator is more useful than a simple virtual keyboard.
In the rectangle function, you should increase the corner options as in the image bellow please, cnc router's users will be very grateful.



Sorry for the long list of wishes, is that I'm very enthusiastic about your work.
My eternal gratitude.
Floris

Note: I don't see any updates for debian stretch.
