"Gcode Exporter" and "Evaluate Image"

[alessandro-zomparelli]

Addressed problem description

Gcode generation for 3D printing (still in the Beta group, because it needs more tests on different machines. So far it works fine)
Added "Evaluate Image Node"
Fixed "Image Node" limit to 100

Preflight checklist

• Code changes complete.
• Code documentation complete.
• Documentation for users complete (or not required, if user never sees these changes).
• Manual testing done.
• Unit-tests implemented.
• Ready for merge.

not sure if this is ready to merge, need try.
I don't handle Gcode, maybe it is easy, but not today

[alessandro-zomparelli]

Sure, take your time.
I've moved the Gcode Node from Alpha to Beta, because I've completed it, but I think that it should be stay in Beta until more test will be done.
So far I have test it directly with only one printer and just compared with Cura with specific settings. The extrusion parameters seems correct, but I'm not sure 100%.

Thanks! I'll start tomorrow a 3 day workshop printing Clay with Sverchok, I think this will be a good stress test :)

Sure, I'll do!
Just one stupid question, should I merge it myself, or you guys have some other checks that you would like to do?

It's my first contribute to a larger repository and I'm not sure on how to proceede now :-P

[zeffii]

change the big green button (using the dropdown button [ v ] ) to "Squash and Merge", that way all the changes appear in one merged PR. then hit

Thank you very much @zeffii !

Hi guys,
this was my first workshop with Sverchok+Clay 3D printing, and it goes really well :-)
I've only spotted a small issue with Evaluate Image, but a minor thing, I'll try to replicate and I'll add it to the issues. Also I spotted a minor issue with Spiral generating Vertices as Lists instead of Tuples (I passed them to an empty Matrix Apply for converting them).

I had the chance to stress the gcode exporter with PLA (plastic filament) and it worked perfectly, so happy about that. Sverchok worked great as well. Here you can see some photos of the printed objects:

hands down the coolest sverchok-related artwork i've seen so far :) thank you immensely for sharing.

would love to see these glazed and fired. : )

Thank you very much @zeffii !
We have glazed some vases made with Sverchok before. You can find the pictures in my Instagram, it's a public profile, no registration is needed: https://www.instagram.com/alessandro_zomparelli/
