Lazy me all i had to do is to go back and read gr5 replies. I disassembled the bed ,unplug and re tightened the sensor wires then i checked the sensor resistance again and now it's working normally ( i think ). Moral of today !!! always check the forum throughout before posting your problems.

Hey guys !!! Well im facing a new problem ( see previous post ) :( when i power on my UMO+ the ulticontroller is not indicating room temp for the heated bed " 90/0° ". When i try setting the heated bed manually to 100° it start heating up but to no surprise stooped when it reach 100/100 (when in reality heated just 10° from the indicated 90). I tried reinstalling default firmware (cura 15.04) but still the same. I wonder if the temp sensor is busted. Any ideas ...i would really appreciate your help. PEACE

Hello everyone, since the UM2 and the original+ shares the same heated bed & electronics i though i could share my personnel experience with heated bed problems. Mine stopped working while printing at 100°C (for ABS) which had caused lifting problem to my raspberry pi 2 case :(. I waited for the print to finish and tried to set bed temp manually, no error message or anything just the ulticontroller continuously indicating room temp, the nozzle heat up just fine so i knew that this problem was related to the heated bed wiring, i dissembled the bed to get access to the connectors. First i set the bed temp to 100 and checked the voltage with the help of a multimeter via the 2 thick grey wires yet to my surprise the reading was pretty normal around 24.3 V but after a close inspection of the connector doc i noticed that the soldering of one of pins had melted down and voilà !! that was the problem. So i just had to do some soldering and while there i reinforced the other 3 just in case. I hope this could help you out. PEACE 8)
