# Plotty (GCode Generator for Pen Plotter)

This is the ongoing replacement extension for the old [Plaster](https://gitea.fablabchemnitz.de/vmario/Plaster). We us this for our self-build pen plotter called [Plotty](https://wiki.stadtfabrikanten.org/books/projekte-und-bauanleitungen/page/xy-stiftplotter-plotty "XY-Stiftplotter - "Plotty"").
