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..

* PID Bed Heating
*
* If this option is enabled set PID constants below.
* If this option is disabled, bang-bang will be used and BED_LIMIT_SWITCHING will enable hysteresis.
*
* The PID frequency will be the same as the extruder PWM.
* If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
* which is fine for driving a square wave into a resistive load and does not significantly
* impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W
* heater. If your configuration is significantly different than this and you don't understand
* the issues involved, don't use bed PID until someone else verifies that your hardware works.
