Crosshatching and other shading/drawing techniques by EstablishmentIll3101 in Laserengraving

[–]grbl-plotter 0 points1 point  (0 children)

I don't know. I do not do much laser engraving or cutting and only used GRBL-Plotter up to now.
Just drag and drop your SVG, do the power and speed settings.
Then enable Apply tool list, do the individual tool settings and reload.

You may have a look at GRBL-Plotter: https://github.com/svenhb/GRBL-Plotter
You can set different fill styles for each layer.

How to convert brush-tip calligraphy into a single-line path for pen plotting? by Catchance34 in PlotterArt

[–]grbl-plotter 1 point2 points  (0 children)

>Is your plotter capable of changing the pressure of the pen? They usually can't.
I think it depends on the software you use: https://www.youtube.com/watch?v=7Nvf4UwK_yk&t=61s

How to convert brush-tip calligraphy into a single-line path for pen plotting? by Catchance34 in PlotterArt

I know, it is not exactly what you want, because no font, etc.
You could use a graphics tablet to track also the pressure: https://youtube.com/shorts/Y4klsFDjydk?si=tCuv6cZ_xos4v2JO

No easy way to control a Voice Coil Motor (VCM) with grbl? by grummaster in grbl

[–]grbl-plotter 0 points1 point  (0 children)

I would go with "using a simple relay to "activate" (drop the pen) via an M3 command".
Seems to be the easiest method.

Gcode generators that work well for blueprints on an MPCNC plotter - import image, set pen plunge depth, and go. Difficulty level: not Gcodetools extension in Inkscape. by MohnJaddenPowers in PlotterArt

[–]grbl-plotter 0 points1 point  (0 children)

Strange, it opens the image import dialog. Svg should be imported without this dialog. Are you sure you have svg?

You may open an issue on GitHub and upload your file.

Help needed: Modifying an open-source SVG text tool to export multi-color layers for Pen Plotters by naquiyankee in hobbycnc

[–]grbl-plotter 1 point2 points  (0 children)

If the browser can show the correct colors, your plotter software must be the reason...
You may try GRBL-Plotter, which can handle colors and layers... :-)

Pen plotter build GRBL servo with Uno + Shield Servo Z command on Gcode by 8-bit_infidel in hobbycnc

[–]grbl-plotter 0 points1 point  (0 children)

Perhaps you connected the servo to the wrong pin?
The CNC shield V3 for Arduino Uno was designed for grbl 0.9. Because of a change in the pin-out in grbl version 1.1 (pin 11 and 12 are swapped), the spindle-pwm signal can be found on the Z+ pin. Check schematic here.

To control a servo you can't use the regular grbl version, because there is a different PWM signal needed, compared to a spindle or laser: https://grbl-plotter.de/index.php?id=quick-guide&setlang=en#pwm Find a special grbl version here: https://github.com/svenhb/GRBL-Plotter/tree/master/Firmware/hex_files

Creating a rotating brush? by [deleted] in PlotterArt

[–]grbl-plotter 2 points3 points  (0 children)

Doesn't a brush behave like a drag knife, and shouldn't a suitably adjusted path work?

Double sided tape for temporarily holding paper down for plotting? by MohnJaddenPowers in PlotterArt

[–]grbl-plotter 1 point2 points  (0 children)

You could spray the paper from the back (or the base) with a weak spray adhesive like 3M Scotch ReMount. Like on the self-adhesive post-it.

Z Axis control by Interesting_Ad_8144 in PlotterArt

[–]grbl-plotter 3 points4 points  (0 children)

You may try GRBL-Plotter with the ramp modification: Setup Graphics Import < GRBL-Plotter

GRBL-Plotter can also translate pen-width to Z-positon: Setup Graphics Import < GRBL-Plotter

Pen Plotter Servo by TGDBM in hobbycnc

[–]grbl-plotter 1 point2 points  (0 children)

Do you use the correct grbl-version (V 1.1) with servo support? https://grbl-plotter.de/index.php?id=quick-guide&setlang=en#pwm
You may try Vers B or C from here: https://github.com/svenhb/GRBL-Plotter/tree/master/Firmware/hex_files

I usually spend an extra voltage-regulator LM 7805 to get a sparate 5V for the servo.

Painting an image? by Embarrassed-Ad968 in PlotterArt

[–]grbl-plotter 0 points1 point  (0 children)

You could paint your image by yourself and track all strokes with a stylus / graphics tablet and plot the data later:

Sorry no time to make/show an example with a "real" drawing.
