Title: Rhino: 2D path to g-code
Post by: mbele on April 19, 2013, 03:53:13 PM

Hi

I've attached few scripts that I use to generate g-code from curves drawn in Rhino. Supported curves are lines, arcs and circles, so before executing scripts, paths should be converted to lines/arcs.

SegmentsIO - import/export paths (evaluation version does not alow but 25 saves)

2DPath2GCode - creates gode from planar lines,arcs and circles. One polycurve (joined lines/arcs) is treated as one continous feature. If you're getting weird paths from polycurves that overlap at subcurve start/end points, try turning off "simplify" option.

Holes2GCode - creates gcode for drilling holes from circles and/or points (other curves will be filtered out after selection)

Cheers
disclamer: use at your own risk :)

ps. if you find bugs, please post seg files here

I don't use Rhino, but I wanted to take a moment and thank you for taking the time to contribute to the community here  :)

Thanks,
Dave

Hi

some updates and few more scripts:

3DPath2GCode - creates gcode from non-planar lines and arcs planar in XY/YZ/XZ (non planar arcs and curves should be converted to lines)

HelicalDrill  - creates helical (circular ramp) gcode based on selected circle path diameter, adjustable stepdown per turn or ramp angle

ProfilePath - creates simple closed profile curve with arc lead-in and lead-out

FacePath - creates simple path for clearing rectangular surface

CircularPocketPathPilot - creates closed or open spiral path for clearing circular area, assumes there's pilot hole allready drilled (eg. with HelicalDrill)

CircularPocketPathIsland - creates open spiral path for clearing area between two concentric circles (no lead in move, you can use HelicalDrill to create start of pocket arround island)

Spirals in circular pocket paths are created using variable stepover trying to keep TEA below allowed maximum - which is calculated from stepover specified for linear path. For ProfilePath and CircularPockedPath*, be sure to turn off "Simplify" option if used with 2DPath2GCode

Cheers

Hi Mbele,

As Dave has already said, thank you for taking the time to post this information which I am sure will be most helpful to others.

Tweakie.

@mbele You still around?

Thanks for your scripts. I have used them with some success, bus was curious if there are some instructions for them?

You're welcome, I'm happy that you use them. I thought that options are self-explanatory, so I didn't write any instructions... I wrote some info for you (will do more later) and I've attached last versions of the scripts I use. There are still some bugs to work out (sort routines, HSM stuff) but they are usable if you're lucky or find a workarround - if you provide usable feedback, I'll fix them :)

In the meanwhile, if I can help you with something specific, please do ask.

Cheers
Mihael

@mbele Thank you for the effort to write this scripts. I was looking for a simple solution to generate g-code from basic lines in Rhino and I found this project. It is possible to customize the post-processor and if so how to do it?

I am using RhinoMAC and unfortunately RhinoMAC it's not running the .rvb files. Any chance to convert this scripts to python so that I will be able to use them? Please can you provide a short video explaining how do they work, or at least some screenshots? I think this project needs more publicity because a lot of peoples who have similar needs they just don't know about this project!

Hi Dacicusan, I'll be very bussy 'til the end of september, and then I'll do some more work on these scripts (bugs and docs). Python conversion should be straightforward, and if I manage to re-eval latest version of rhino for testing (after 90 days plugins stop working), I'll try to do it.
cheers

Thank you for the answer. At least until then please can you write a help file for how to customize the post-processor if this feature is possible?

Title: Re: Rhino: 2D path to g-code
Post by: mbele on July 16, 2017, 03:51:13 AM

There is no postprocessor. Gcode is generated during curve evaluation. If you want to customize something, open the rvb file in text editor and edit strings. If you need help with something specific, ask away.

Hi mbele. It's October already and thinking that maybe you will relaunch the development of this scripts. Waiting impatiently to test them. A translation to Python will be very helpful also. Unfortunately I don't know how to program by myself. Want to learn Python.
