Summary

Part 1. Preparation - Software and Hardeware

You can prepare AI-generated tools in advance, such as Midjourney and Stable Diffusion. With these AI tools, you can design sticker materials that fit the theme style, and then convert them into SVG files using vector software such as Inkscape or Adobe Illustrator.
Or download some free resources on the Internet. It is recommended to use free commercial SVG file resource websites, such as Freepik. Please note that when using free resources, please indicate the author's source as required, or choose a paid version to avoid copyright issues.

What's more, you also need to download the control software of UUNA TEK 3.0 to control the machine to draw corrently here: https://uunatek.com/pages/downloads

We're using UUNA TEK 3.0 Highend All-in-One Pen Plotter Drawing Machine in this example, make sure you had already owned this machine, if not, you can purchase here at the best price.

Part 2. DIY Halloween Decors with Inkscape

Step 1. Generate unique Halloween decorations or spooky wall art images through software such as ChatGPT or Stable Diffusion:

Step 2. Import the generated image into Inkscape to create an SVG line file. For simple patterns, you can directly use the pen tool (draw bezier curves and straight lines) to create the path along the outline of the pattern, as shown below:

Import the generated image into Inkscape



For complex patterns, you can use the Trac Bitmap function under Path to automatically convert the path (generally use the default parameters):

use the Trac Bitmap function



Note that the generated svg path overlaps with the original image, and we can use the mouse to drag them and separate them:

use the mouse to drag them



For easy viewing, we can adjust the display mode and change it to outline mode to see the final effect (in order to decide whether to fine-tune the parameters of the trace bitmap):

adjust the display mode



For some unwanted materials, you can double-click the generated path, select and delete the unnecessary points by right-clicking (for example, the text effect here is not very good, so delete it and create it again with a pen):

What's next, combine them to get personalized Halloween spooky wall art materials:

Step 3.Then make some detailed adjustments to the text, so that the path filling effect can be achieved later. We select both the inner and outer paths of "A" at the same time, and then use the Exclusion tool under Path to remove the triangle in the middle to generate a circular closed path (in preparation for generating the fill path of the text later).

Then make some detailed adjustments to the text



In order to conveniently view the generated effect, we fill it with color. The effect is as follows:



Similarly, we generate other paths, and the effect is as follows:

we generate other paths



Step 4. Generate the fill path of the text (because the current text only has outline lines, if you want to achieve path drawing inside text or other closed graphics, you need to generate an automatic path for filling). Select the Hatch Fill function under iDraw Utilities:

Generate the fill path of the text
Generate the fill path of the text



Since the thickness of the brush determines the size of our hatch spacing, we first simulate the actual brush thickness on Inkscape according to the corresponding pen thickness, so that you can basically see the final effect of the drawing, and adjust whether to enlarge or reduce the pattern and rearrange the pattern according to the pen thickness to get the appropriate effect.
First, select the path to be drawn with a black pen and adjust the diameter of the pen (I use a pen of about 0.45mm):

adjust the diameter of the pen



Then adjust the thickness of orange and other colors in the same way. I use a marker of about 1mm. The effect is as follows (you can see that the thickness of the two pens is different):

adjust the thickness of orange and other colors



Next, return to the Hatch Fill function. I set the fill spacing slightly smaller than the pen size (0.8mm) so that the text can be completely filled through the overlapping parts (of course, it can also be set slightly larger to simulate the effect of striped fonts, such as 1.5mm, you can try it yourself):

return to the Hatch Fill function
return to the Hatch Fill function



After filling all the patterns that need to fill the path, the effect is as follows:

Part 3.Start Drawing with UUNA TEK 3.0

Step 1. UUNA TEK3.0 software provides the function of layering and painting by color, so we must ensure that the patterns that need to be layered are filled with the same color. We have four pens here: black, orange, green and purple. First select all green paths (you can drag and select or hold down shift and click with the mouse to make multiple selections), and right-click to select Group to combine them into a new group for later layering:

right-click to select Group to combine



Other colors can also be grouped like this.
Step 2. Fill the colored paths. UUNA TEK3.0 software layers based on the color of the path, so you need to fill the path with color in advance, that is, use the "Fill" function to give the path color (you can see that the result is different from the "stroke paint" operation above):

Fill the colored paths



The final effect is as follows:

Fill the colored paths



Step 3. start drawing with UUNA TEK 3.0
Open the SVG function of uunatek3.0, check the "Color" option, open the file from "File->Open", and you can see the effect of color layering:

Open the SVG function of uunatek3.0


When you want to draw a black pattern, uncheck the layers of other colors and hide the patterns of other colors first:

uncheck the layers of other colors


Then generate gcode to draw the black part:

generate gcode to draw



After drawing, change to other color pens and draw the corresponding color texts in turn. The final effect is as follows:

change to other color pens
