UMO problem with HBK

[matijamataja 0]

I have problem with my heated bed (from Ultimaker). When I turn the printer on I get message MAX TEMP ERROR on Ulticontroler. If I disconnect the heat sensor of bed the ulticontroler shows 70 C/ 0 C for bed.

 

I have already checked the resistance on heated plate and they are fine (112 Ohm) and also

heated plate gets hot (so no problems with heated plate). I have checked different versions of Cura but no difference.

I assume that I got the bed with broken heat sensor PT100.

My question is if my assumption is right, and what to do now. Is the heat sensor part of PCB of heated bed kit? Would I need to replace PCB to solve this problem?

Any suggestions or ideas for solution of this problem would be more then welcome.

Although the designs differ slightly with our heated beds.. I had this issue for a brief bit on my UMO+. Have a good check of the wires and connections to the board. On mine, I gave the wires some slack, and checked the connection of both sets of wires. Fixed my problem.. sounds like it's something simple
