最近、USBシリアル接続を介してTronxy 3DプリンタをUbuntu Server 20.04を実行しているLinuxボックスに接続しました。一部のカスタムマクロの問題を診断するのに役立つように、Pronsole（printrunツールスイートのユーティリティ）を使用したいと思います。 Pronsole環境を起動し、connectコマンドを使用してプリンタに接続でき、問題やエラーは発生しませんでした。ただし、たとえば、Pronsoleを介してgcodeコマンドをプリンタに直接プッシュすると、コマンドラインG28に次の出力が表示されます。私はLinuxエラーやPythonに慣れていないため、これらのエラーを読み取れないか、解決策を見つけるためにGoogleで何を検索するのかわかりません。私は本当に説明の助けを探していると思います。

まあ、私の問題はソフトウェアの問題ではなく、ハードウェアの問題であることがわかりました。 3Dプリンタがコマンドを実行しようとするたびに電源が切れ、USBシリアルコントローラとホストコンピュータの接続がしばらく切断されます。
