A1 Plotting FAQ
Will pen plotting damage my A1?
No. Pen plotting only uses X/Y movement at low speeds, no heating, no extrusion. The pen holder is lightweight (under 20g) and movements are gentler than actual 3D printing. Many users plot for days without any issues.
What pens work with the A1 pen holder?
Our pen holder fits standard pens and markers: Sakura Pigma Micron, Staedtler fineliners, Sharpies, Stabilo, gel pens, and most pens with 8-12mm diameter. The spring-loaded design accommodates slight variations.
Can I still use my A1 for 3D printing?
Absolutely! The pen holder clips on and off in seconds. Switch between plotting and printing whenever you want, no permanent modifications needed.
What's the maximum plot size on A1?
The A1 has a 256×256mm bed. Due to the pen holder attachment offset (28mm in front of the extruder), the maximum plot area is 256×228mm. Perfect for larger artwork and detailed designs.
Do I need any software besides 3DPlotter?
No. 3DPlotter is an all-in-one web app, create designs, generate G-code, and export. No Inkscape, no plugins, no command-line tools. Just your browser.
