Hi i have a duet3d wifi 1.04b model is a new build and i see the led of heater bed is always on and not cut, i try to extract the sd and is the same and i try conect my bed and get hot, then i try to start the hotend to see is work and get smoke on my cartridge i off it fast but now i try to start e0 or e1 heater and the led is always of, i know maybe the mosfet or bed is broke but why not works the other heaters right? And other question i have other board and i not use the e1 heater, if i take this 036n04l mosfet for the other board that's one work fine whiteout it? Sorry for my English. And is new build never use the board before but is old i buy in 2019 but i stop the project and start again now them i think not guaranty.. Thanks.

Just to confirm, the heater turns on even when the SD card is removed?
Can you show a photo of the wiring?
When and where exactly was it purchased?
-
@Phaedrux yes i try whiteout sd and is same problem the led is always on, i buy it in Spain to a reseller Héctor in telegram group but long time ago 2019 but i have a personal problem and stop the project and start again now . Look the all board nothing is burn (i look the 3 mosfet from bed, e0 and e1) and the fuses are good.
And picture: -
Is this the first time you've tested it? Did it every work?
-
@Phaedrux yes is the first time i now connecting and comfigurate it never try before, i think the order think work fine, i have panel due working, duet web, endstop, coolers just have problems whit heaters
-
If you had spare heater outputs you could use mosfets to power the heaters controlled by the fan headers.
-
@Phaedrux the problem is i have fan0 and fan1 to layer and the fan2 i got the fan heater e0 set to 45 degrees, i want to fix to normal use. But thanks for the idea
-
I try the mosfet whit a multimeter and yes the bed one is open, the e0 is not open but give me any numbers and e0 is completely colsed, i try to start e0 and e1 but not start and the led always in off just the bed one is on. Them i need change anymore? Or just two these mosfet? Thanks.
-
I'm not exactly sure what you're saying, but if you have the ability to change the mosfets you should change out any that aren't able to control the heater.

Ok i will change this mosfet and try again thanks for your reply!!
