プリンタ３号機は２号機のOctopiと共用していたが、印刷中に１秒ほど停止する事象が発生するようになった。
停止するとその部分がブロブになって印刷品質が悪くなるため、Octopiのラズパイを３から４に交換することを考え４を買ったものの、２号機は３のままで動かし、よりパワーのある４はKlipperを入れて３号機を動かすことにした。
Klipperの導入はKIAUHを使ってFluiddと一緒にインストールした。
あと、RAMPS-FDv2のマザーであるAruduino DUEにファームをフラッシュするのだが、menuconfigを実行した際に選択するポートはプログラミングポートを使用の際はSerialで、ネイティブポートを使用の際はUSBを選択しなければならないらしく、ここで時間を要した。（フォーラムに記述があるだけ）
xChangeを使用したシングルノズルのマルチエクストルーダ構成のprinter.cfgは以下の内容で一応動いている。
# This file is an example config file for corexy (and also h-bot)
