Duet 2 Wifi Heated Bed Heating all the time
-
I bought Duet 2 Wifi Card V1.04 it was ok for a while(8-10 Months). Few months ago I powered my printer (Ender 3 pro few days it was off) it started heating the bed immediately, fortunately I spotted it soon enough, it was 100 C. I suspect it's Heat-bed Mosfet because LED Next to it is always on , Everything else looks like working. Is there anything you can help me with? I'm building CoreXY from scratch and wanted to use this board. I could reuse E1 + SSR but I need two extruders too.
Thank you in advance.

@rbalandis you could use RRF3 and configure a controllable fan port to control the SSR

My guess, I would need to modify Firmware itself and I cant do that through DWC?
Thank you for suggestion if nothing else I'll try that.

you'd just need to set your config.g accordingly.
RRF3 is very flexible on pin assignment

Is it as simple as changing bedheat to fan2?
; Heaters M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp M950 H0 C"fan2" T0 ; create bed heater output on bedheat and map it to sensor 0 M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 -
@rbalandis yep.
