    I want to make your life easier. Which of the following would help more?

    a) a full list of supported gcode, the syntax, and what it is for

    b) a tutorial about writing your own conversion style in java

    c) a tutorial about writing your own generator in java

    d) something else (please be specific)

    I would like to know how can i compile the project in IntelliJ IDEA?

    Thank you in advance,

    I really like the GCode list. Thank you.
    As a progression at school, the Cartesian grid is the place to start. Eventually (like in Middle School), I hope my students would understand GCode, much like html. Don’t know if there are any like-minded educators. For example, having students draw a picture from GCode on paper would be a good offline experience.

    March 13, 2018 at 13:11 #19395

    Makelangelo software can load a gcode file, which will immediately be displayed in WYSIWYG preview.

    It may help to tick the box in preferences > graphics > show pen up moves

    So it would seem that with Scratch support now included, A-C are completed. Neato.

    New here too.

    Hope for a good start here.

    as a makelangelo fan:

    wireless connection
    tool/pen changer
    endstop usage / easier homing and easier machine size control
    easier usage without LCD ( skipping “click to continue” step ) maybe someone shares the gcode for skipping that step
    different approach to Z axis / being able to use brush and getting different linewidhts with servo angles

    would be perfect

    flying makelangelo
    wacom2makelangelo or wacom2gcode2makelangelo / realtime drawing
    DIY tutorial for dummies like me

    still. I love my makelangelo

    1. I’m looking at options for a wemos/esp* brain that would be wireless.
    2. what do you mean? automatic pen changing? foo… that’s a big ask for a polargraph.
    3. Possible on the M3 with a few changes.
    4. I could add a toggle in the software to not add the message, beep, and wait for click.
    5. not sure what you mean here.

    what kind of diy tutorial? Do any of these help? https://mcr.dozuki.com/c/User_Guides

    1. great news
    2. maybe starting with double pen holder (like double extruder) is a better idea. I’ve found this “Servo actuator for pull and push” on thingiverse / https://www.thingiverse.com/thing:2305061 /
    probably “secondary pen down” angle will be needed on software.
    3. what kind of few changes? / I have an extra couple of endstops
    5. let me put it this way: different pen down angles for different lenght of lines. for example: if the line is long (let’s say 20 cm) pen will be closer to paper, if the line is short (5cm) pen/brush will be far ( I currently do some experiments with brushes, so any dynamic pressure can be sexy)

    For #5 you’re really looking at making your own image converter. In your place I’d get familiar with how the existing converters work and then write a new one (or tweak an existing one). Way better than waiting for me, much shorter development time.

    1. It would be nice to have an option to disable M226 in g-code generation.
    2. It would be nice to have an option to adjust paper position (vertically and horizontally) directly. Instead of cheating by changing the polargraphs height.
    3. When generating gcode in Makelangelo software the size settings for the polargraph do not show up (as a comment) in the g-code. For convenience it would nice to have a comment in g-code stating some stats like polargraph/pen settings.
    4. Following number 3. is it possible to have the g-code generated relative to polargraph settings within the g-code? What I mean: At the beginning of the g-code, the width of the machine and the size of the paper is printed. The arduino calculates the movments based on these settings? This way it would be possible to change the outcome by just changing the settings at the beginning of the g-code. I think this is not trivial. Is this even reasonable? And how does Makelangelo reacts to SVGs created with inkscape when they are directly run off from the SD card?

    May 3, 2019 at 15:40 #23185

    1. I looked into this. it is not trivial to implement. The simplest way I could find was to ignore m226 in the firmware.

    2. early versions of the software had this. I abandoned it in favor of user-friendliness. An expert panel for custom machine with all the bells and whistles might work. By default most image manipulation code probably assumes paper at the center of the drawing area.

    3. that wouldn’t be hard. make an issue ticket and I’ll see if I can do it sometime soon.

    4a. g90/g91

    4b. It uses dimensions for kinematics, but the gcode position commands are not tied to the machine size. You could change machine size commands and the rest of the code would still work.

    4c. makelangelo-firmware cannot read SVG files. They must be converted to gcode, then put on the SD card, then run from there.

    June 4, 2019 at 09:48 #23546

    Loading an SVG/DXF into the Makelangelo software always centers the content of the SVG. Alignments are irgnored.
    This is a problem when drawing with multiple colors. However, there is a “switch color to…” function in the firmware for the internal CYMK art style. It’s just not useable for anything else then the CYMK style.

    I have two layers in Inkscape for different colors. When saving each layer into a separate file and loading them successively into the software, they get centered automatically destroying the different alignments I had in Inkscape.
    AxiDraws Inkscape plugin is able to successively draw layers. This would be nice to have it in the Makelangelo software.
    As I am writing this I got the idea of trying the 4xiDraw Inkscape plugin with the makelangelo firmware.

    June 4, 2019 at 11:50 #23547

    So you need a “center/don’t center” and maybe a “resize/don’t resize” option? I’m looking for the best way to implement this.
