====== Upgrade to Prusa MK4S 🇬🇧 (Feature) ======
\date //2024-10-15//\\

{{ :blog:ig24:241015_1.jpg?400 |}}

The prospect of much improved part cooling drove me to upgrade my Prusa MK4 printer to the MK4S variant. (The high flow nozzle was not so interesting since I installed a Chinese 0.6 mm CHT clone nozzle from the beginning). The assembly was straightforward and the good Prusa documentation didn't leave much need for guesswork.

After the upgrade, I also ran a volumetric flow rate test as developed by Stefan from CncKitchen. I used [[https://hotend-flow-tester.netlify.app/|this online tool]] which directly generates G-code.

Something I could not manage yet is to find good pressure advance and retraction settings for TPU. More fiddling will be needed in the future.

Just for documentation, here's the stats of my printer as of mid October 2024 🤓
