Gcode missing Tool callout and spindle speed

Post by WillyNilly »

I have recently installed the full versions of both vcarve and 3d cut, for a shopsabre 48x96.

Using either one generates g-code that is missing the tool callout, spindle speed, and a few other lines I don't know.
We have other users of vcarve who do not have this problem, I am using the same tool library and post-processor as they are.
This may be a setting that I have neglected or a problem with my installation.

Here is an example of the 3dcut generated g-code;
G90
G0 Z0.2000
G0 X0.0000 Y0.0000
F236.2
G0 X32.4859 Y15.9108 Z0.2000
G1 Z-0.5000 F78.7
G1 Y14.3770 F236.2
G1 X32.4813 Y14.3662
G1 X32.4650 Y14.3332
G1 X32.4433 Y14.2884
Here is an example from vcarve at the machine;
G90
G0 Z0.8000
G0 X0.0000 Y0.0000
M5
T3
S6000
M3
g4 x 4
G0 Z0.8000
G0 X0.0000 Y0.0000
F160.0
G0 X30.8214 Y39.9555 Z0.2000
G1 Z-0.2333 F30.0
G2 X31.0379 Y40.0805 I0.2165 J-0.1250 F160.0
G1 X31.5714
G2 X31.8214 Y39.8305 I0.0000 J-0.2500

Vcarve at my pc is missing the same section of code in my .tap files.

I also run a Busellato Jet Star, 3dcut and vcarve work just fine for generating that code.

Has anyone experienced this before? I can manually add the missing block but I expect to be generating 100's of toolpaths in the next few weeks and I don't want to edit all of them.

Are you sure you're using the same Post Processor as the other users? The name might be the same but it doesn't mean the contents of the Post Processor are.

As far as I can see none of the standard ShopSabre Post Processors supplied contain code to set the spindle speed.

That may be it, the post-processor at the machine could be edited, do you know the file extension Vcarve keeps the postprocessors in? I can't seem to find the folder. I can find it in 3d cut.

For Cut3D you'll need to look in the PostP folder which is in Program Files/Cut3D. The names of the Post Processors aren't quite the same as those you seen on the drop down list so you might have to edit it a few ShopSabre one and look at the POST_NAME section to narrow it down.

VCarve Post Processors can be found in the PostP folder that you get by clicking on Open Application Data Folder on the File Menu.

I see it now, they are different, it must have been tailored to our machine. I'm new to the vectric software, It seems highly editable, I like that. Thanks for your help.

On the VCarve Help menu there is a document that explains the sections of the Post Processors which will come in handy if you do want to modify them.

Oh, I will be modifying them, carefully of course.
