I recently installed an new Octopus V1.1 after I accidentally shorted the old board. Until now I completely reflashed the Raspberry Pi 4 and Octopus board and set up the printer.cfg config but now the bed simply wont heat anymore. I have checked the wiring, Termister, SSR, changed output to PA3 instead of PA1, thermal fuse and connection. Everything else is working and now I believe its something in the config or setup I did wrong. When I tried to reverse the pin (!PA3) it immediately heats but otherwise klipper simply restarts. I hope someone can help me.

And the old board was an octopus? It looks like it isn't reading any of your hardware. did you flash the firmware on the the new board?

The old board was an Octopus Pro but I flashed the new one and everything else is working. I also tried different SSR´s, different ports and different usb cables. It seems like it can´t control the SSR but voltage is constant. I´m really clueless because everything technical works just fine.

That's funny, your log says that it can't find your steppers

Yeah I know. I removed every stepper except the one of the extruder because I fear to overpower the board and simply dont wont to buy new ones. I also discoverd that the target temperature stays at 0 even if I try to heat it to 50 or 100 degrees.

could you elaborate?

The drivers don`t have to do anything with the bed but I also changed some little things in my system and after I tested the motion system I simply removed them. Electronics wise everything works just fine. I reviewed my klipper log and it shows that it wanted to heat to 50 but shortly afterwards reboots without any shown errors. Honestly I´m completely clueless because I flashed the pi and board multiple times, checked all connections and it seems like it´s software related

Update.. my powersupply just smoked. Maybe it`s the heater which is shortend or something.

If you're running an AC bed (which should be the case with a 2.4, and definitely with the LDO kits) the power supply shouldn't have anything to do with the bed heater.

Yeah it’s an AC bed but isn’t it really inconvenient that the power supply dies right after?
