The Prusa Open-Access knowledge base is organised around workflow scenarios that would require modifying hardware and g-code. The workflows are divided into two segments:
Materials, with a list of thermoplastics that are available on the market, their traits, and various hardware, software and troubleshooting links to them.
G-code experimentation, with links to case studies such as DeFextiles. These generally manipulate g-code to generate movements and extrusions that aren't typically achievable with a regular slicer.
