How much current can TH4 deliver and which voltage range is supported? I have only 24V fans and don't want to fry my board and / or have my fans running too slow (would like to control two fans simultanously over that pin)Thank you very much for your instructions! They helped me a lot already.
What about a second fan? I mean... the e3d hotends need active cooling, so one can drive two fans for two e3d hotends from pin P2.4. But where to connect a cooling fan for the object-cooling during print? Even if Pin 2.4 can provide enough current for three to four fans (at 24V in my case) hotend-fans and printing-fans need to be controlled separately. Any suggetions?
