REBEL 3D

Mám nainstalovaný marlin 1.1.9 na MKS GEN-L.
Je tam 24v zdroj. (18v se neosvědčil nefungovalo správně USB...)
Díky tomu topí vše několikenásobně intenzivněji než na 12V.
Nastavil jsem max hodnotu u bedu na +-100 z 255 a u HE na 50 (25 bylo už málo).
Nastavím na hootendu a na BEDU PID regulaci, u bedu to krásně funguje. U HE jede furt bang-bang ať dělám co dělám (teplota furt kolísá +- několik stupňů a power jede furt na max povoleného nebo vůbec, což vidím v repetieru)...
Už jste se s tím někdo potkali?

takhle vypadá poslední pokus..

Stejny problem.

ted jsem nahral Marlina 1.1.9 do nove kostky a resim totez. Teplota lita na extruderu +- 3 stupne, parametry z autopid nemaji zadny efekt .

Nema nekdo nejaky tip, co s tim? Bed se chova spravne.

LS.

Zkusil sem z toho vyhodit #define PID_FUNCTIONAL_RANGE 30 ale to odmítne zkompilovat, tak druhej krok byl nastavit to na 200 a první test při 245°C se tvářil že drží teplotu v rámci jednoho stupně, tak snad to bylo ono. Osobně mi není jasné k čemu to přepínání z bamg bang má být (čas to podle mně moc neušetří) proč to nenechali jen jedno či druhé...

Potvrzuji.

Po nastaveni PID_FUNCTIONAL_RANGE na 200 neni na grafu teploty sinusoida, ale rovna cara. Asi je nekde chybka ve vyhodnoceni toho parametru .
