[Tinker firmware - introduction]

The headbed of my UM2+ does not cool down anymore (temp keeps rising).

I think the mosfet for heater3 is broken and i'm not really in the mood of buying a new mainboard 😉

 

The mainboard has 3 heater terminals:

heater1 (occopied), heater2 (free) and heater3 (this is the heater for the headbed).

I also see that there are 3 seperate mosfets for all these 'heaters'.

 

So, i'm thinking, using the Tinker firmware, is it possible to use the 'heater2' terminal (not occopied) on the mainboard for the original headbed?

 

@tinkergnome Is there maybe a setting/option in the Tinker firmware to set heater2 as primary heatbed?

 

BR,

Ray

I have same Issu but the heater dont work, so never start printing

 

Did you change the pin? because we can swtich to heater 2, but I dont know if the current would be supported because the mainboard has a finder relay 361190054011 that i dont know what is for...

 

So if you could do it, please tell us, I will do it too and tells you

 

Thanks!
