Max temp Error! - solved

Recommended Posts

I woke up this morning to my print being prematurely halted and my UMO ulticontroller stating "error: max temp". I turned off the printer then turned it back on to restart the print. Print started fine, but when I came back 20 mins later the same error message was there and my nozzle said it was well over 300 C!

Why is my printer giving this error about max temp? How can I fix it?

+1 on the wires... Its a somewhat known problem that these can be subject to loose connections, short circuits, noise, etc. which can cause temp errors and or/weird temp readings...

Check the ones connecting your temp sensor with the small amplifier board on top of your print head, as well as the ones that connect that board with your um main board underneath the printer.

Gentleman it seems the problem is resolved! I followed the advice by Gr5 and found that the some of the wire plugs underneath my printer were half unplugged. I pushed them all back in and now I'm 40 minutes into a print when the last two have failed by 20 mins. I love this forum, thanks for the help. :)
