M112 – nouzové vypnutí – po něm je pro další práci nutný FIRMWARE_RESTART

RESTART – reload konfigurace a interní reset služby

FIRMWARE_RESTART – stejný jako RESTART navíc smaže chyby v mikrokontroleru tiskárny

PID_CALIBRATE HEATER=extruder TARGET=220 – kalibrace pro eliminaci kolisani teploty extruderu

PID_CALIBRATE HEATER=heater_bed TARGET=80 – kalibrace pro eliminaci kolisani teploty podložky

SAVE_CONFIG – uloží hodnoty z kalibrace do konfiguračního souboru

PROBE – umožní kalibraci správného offsetu pro osy X a Y (použij G1 a GET_POSITION pro získání hodnot a potom edituj konfiguraci)

PROBE_ACCURACY – ověření opakované přesnosti v ose Z

PROBE_CALIBRATE – nastaví režim kalibrace osy Z, nyní stačí nastavit osu Z pomocí ovládání v octoprintu nebo G-CODE příkazy

TESTZ Z=-.1 – umožní kalibrovat/nastavovat osu Z ještě níže

ACCEPT - potvrzení kalibrace osy Z

BED_MESH_CALIBRATE – kalibrace rovinnosti podložky, spolu s visualizací lze také srovnat podložku šrouby, zjištěná křivost podložky se aproximuje při tisku kvůli maximální rovině https://plugins.octoprint.org/plugins/bedlevelvisualizer/

MANUAL_PROBE a TESTZ – pro manuální kalibraci osy Z
