Pen Plotting Blog: Guides & Tutorials for Bambu Lab 3D Printers

G-code is the programming language that tells machines how to move. It controls your printer's position, speed, and pen up/down actions. With 3DPlotter, you don't need to learn G-code—our software generates it automatically from your designs.

It's a simple 3-step process: 1) Print the pen holder attachment using our STL files, 2) Mount it to your printer's print head and insert a pen, 3) Use 3DPlotter to create designs and generate G-code. The whole setup takes about 30 minutes.

We've tested 15+ pens and recommend: Sakura Pigma Micron for fine detail, Staedtler Triplus for everyday use, and Sharpie Fine Point for bold lines. The key is consistent ink flow and a tip that won't catch on paper.

Hershey fonts are single-stroke vector fonts designed specifically for pen plotters. Unlike regular fonts that have filled shapes, Hershey fonts draw each letter with one continuous line—making them perfect for plotting. 3DPlotter includes 50+ Hershey fonts.
