Would like to adress it once more….

I already have some experience with SVGs etc., but multicolor SVGs still open as all in one color.
Is there an example available?

Dear hiphouser,

you can do a lot of things with Makelangelo.
Check this website:

https://mitxela.com/plotterfun/

Export it as SVG and your Makelangelo (clone) will be able to plot it.

Method “Stipples” w/ “TSP Art” checked will bring you very close to what you want. For multi-color convert the RGB file to CMYK and convert to “TSP art” for every layer.

Regards,
Bernd

This answers my own questions:

Just download the release:
https://github.com/MarginallyClever/Makelangelo-firmware/releases/tag/9.2.0

The release version is still Arduino compatible, although it does not cover the CNC shield V3. But it was easy to modify the RAMPS-config accordingly.

Hi Phi Le,

forgot to mention, that there is also a Processing script in Dan’s github where you can see the effect of a misaligned Makelangelo.

Hi Phi Le,

I am not the most qualified person to answer, but the belt length is to my understanding the distance from pulley to the home position of the Makelangelo. My home position is about 307 mm below the zero point, when using a 775 mm wide and 1000 mm height Makelangelo.

There is also a recent instructable which uses the same hardware as you. It might
https://www.instructables.com/BLACKBOARD-V-PLOTTER/

It might help you further. – I already had plenty of hours of fun with my Makelangelo and I wish someone could help me with my issue. After a firmware change my Makelangelo (with a CNC V3) understands and responds to all M- and D-commands, but freezes when using a G1/ G0-command…. I am desperated.

Regards,
Bernd

Dear Dan,

I tried it with a relatively simple SVG file with only two colors. It draws everything in the same color and there is no “pause” etc.

Please find below an excerpt from the SVG I am using.

Do you know where I can find a “working” mulitcolor SVG-file. I could give it a try and may find the issue…

Thanks again!

Dear Don,

forgot to thank you for your fast response and immediate help.
In the end I took the main information from the scratch program and converted it to an SVG outside scratch which I then used to draw it with the Makelangelo.

Btw: Scratch2 is obsolete now because it is based on Flash. Do not know if there are many people who work with Scratch and the Makelangelo. I tried it just for fun and to get my daughter involved…

Perfect. Scratch program is working. – But “Makelangelo”-software still does not understand. Any ideas?

[mrbernd]

Thank you very much! Bernd

[mrbernd]

Dan,

thanks for your answer. I only need the “when I receive” in order to generate a list of primes. Will try to find a different solution…

Regards,
Bernd

[mrbernd]

Dan,

thank you for your questions.
It is a Scratch2-file. The source file and two screenshots are here (WeTransfer-Link).

The main program requires a list of primes which can be generated with the two subroutines.
The subroutines are not mandatory as long as a list of primes is available. Within scratch these lists can be imported/ exported. The code is ready-to-rum and produces the output which I would like to have with the Makelangelo.

Regards,
Bernd

Hello!

Just played a bit with Scratch support. That is a big thing. Simple test files are working. – But my first real project is not. It is not overly complicated but uses a list…

Can share the code, the scratch result etc. Would appreciate if someone has an idea…

Bernd
