nastaveni Auto home do stredu desky

[taunus]

Ahoj chtel jsem vymenit Z end stop za senzor . koupil a nainstaloval jsem Tronxy XY-08N mam ho vlevo vepredu od extruderu. firmware Marlin 1.1.4. problem mam v tom ze puvodni autohome s klasickym end stopem mi sel do leveho predniho rohu. nini bych kvuli sensoru potreboval aby auto home byl uprostred zakladny. tudiz aby napred jel x ,z na endstopy pak se vratili na stred a Z udelalo home ve stredu . Prosim ale za boha na to nemuzu prijit jak se to dela. mohl by mi nekdo stim pomoci prosim pekne?

Mozno v tejto sekcii by sa to dalo nastavit:

Kód: Vybrat vše

// @section homing

// The center of the bed is at (X=0, Y=0)
//#define BED_CENTER_AT_0_0

// Manually set the home position. Leave these undefined for automatic settings.
// For DELTA this is the top-center of the Cartesian print volume.
//#define MANUAL_X_HOME_POS 0
//#define MANUAL_Y_HOME_POS 0
//#define MANUAL_Z_HOME_POS 0

Nieco podobne riesia aj tu:

Ja pouzivam v Marlinu pri autolevelingu "Z Safe Homing"

Configuration.h radek cca 985

// Use "Z Safe Homing" to avoid homing with a Z probe outside the bed area.
//
// With this feature enabled:
//
// - Allow Z homing only after X and Y homing AND stepper drivers still enabled.
// - If stepper drivers time out, it will need X and Y homing again before Z homing.
// - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28).
// - Prevent Z homing when the Z probe is outside bed area.

#define Z_SAFE_HOMING

dekuji moc vyreseno uz to chodi jak ma . jeste jednou moc dekuji. ted pro zmenu se vyskytla hlaska hermal Runaway Protection .toto je zpusobeno cidlem nebo muze byt i jinde chyba?diky za info prvni forum kde dokazi poradit

no, pokud ti to ukazuje spravnou teplotu, tak to bude spise chyba nastaveni PID. Jak se chova teplotni graf ? nebo jinak, jak ti lita teplota ?

Problem je dosledkom prekrocenia definovaneho rozdielu teploty (smerom dole, alebo hore) po definovanom case. Mozes preto skusit zvacsit tento cas na stovky sekund. Napr. 150s pre hotend a 300s pre heatbed.
Problem sa da eliminovat zmenou prahovej urovne a hodnoty hysterezy. V prvom rade vsak doporucujem spravit PID kalibraciu.

dekuji za vyvetleni . pro zatim jsem vymenel thermistor. a vypada to ze je to v proadku
dekuji pekne
