UMO hot end thermister


Recommended Posts

Posted · UMO hot end thermister

Greetings,

I have replaced the UMO board with a ramps 1.4 and everything is complete with the exception of the hot end thermistor. on the UMO, there are two thermistors both with three wires, but only two are required for the ramps board. So I can either use the orange yellow and brown or the green peach and tan. My question is, what two wires do I use to connect to H1 Therm,  in what order and what about the third wire?

 

thank you in advance

    I don’t have an answer for your question, but I have a question of my own.  How did this upgrade turn out for you? Was it indeed an upgrade or do you find that the original ultimaker board and firmware was superior than what you got from Ramps? I know the 19v is a pain, but the firmware and cura compatibility seems like it may be worth it. I’d love to know your thoughts on this.
