Vitaris/StickerCutterThis project aims to repurpose a non-functional large format printer into a sticker cutting machine.
StickerCutter is an open-source printed circuit board by Vitaris, from the Vitaris/StickerCutter repository on GitHub. It is a 2-layer board of 111.1 × 164.5 mm with 29 parts on 50 nets, routed with 346 tracks and 0 vias.
It is built around the BTS7960B. Its parts include 6 switches, 5 connectors, 4 ICs, 2 diodes and 1 resistor. It belongs with the RP2040 boards of this library.
Converting a large format printer to cut stickers
Project Overview
This project aims to repurpose a non-functional large format printer into a sticker cutting machine. The system will be controlled by a Raspberry Pi Pico rp2040 microcontroller board. An optical sensor on the former print head will detect marks around printed stickers, and a blade on the print head, which originally cut the print job after completion, will now cut strips of stickers. The project is written in C and will be released as open source on GitHub.
Mechanical Modifications: The printer's existing printing head will be adapted to function as a sticker cutting head. This will involve adding an optical sensor to detect markers around printed stickers.
Software Control: The Raspberry Pico rp2040 will control the cutting process. The software will interpret the signals from the optical sensor and instruct the cutting blade accordingly.
Language & Platform: The project will be implemented in C language for the Raspberry Pico rp2040 microcontroller platform.
Open Source: This project will be open source and hosted on GitHub, allowing for collaboration, contributions, and improvements from the community.

The 25 most common of 29 parts.
It measures 111.1 × 164.5 mm and has 2 copper layers, 1.6 mm thick.
29 parts, built around the BTS7960B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Vitaris/StickerCutter repository on GitHub, at the commit this page was made from: the board is pcb/StickerCutter.kicad_pcb and its schematic pcb/KiCad-RP-Pico-main/Test/Test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Vitaris before reusing the design.
