Ultimaker 2+ Extended Heated bed Temp issue

Recommended Posts

Posted · Ultimaker 2+ Extended Heated bed Temp issue

I noticed recently that a few things were coming loose on the bed of one of my Ultimaker 2+ Extended machines while printing and I just couldn't understand it. But then I happened to touch the glass plate while running a print and it was warm, but not near the 60c i had it set to(its displays 60c in the menu). So sure enough I got my thermometer out and measure then bed at about 40c, not 60c. If i increase the set temp to 75c I'm getting around 60c. My thermometer is a bit crappy so it could be off by 5c.

I use hair spray on the glass plate usually which is why the things were coming loose, it needs around 50-55c to hold PLA down. I use it more as a release mechanism rather than to hold the print in place.

 

Anyway, I checked all the connections and everything looks fine and I'm not getting any errors. Its the newer print bed as I purchased and installed it late last year.

 

Any ideas as to what it might be? I mean i can print fine if i just tell it to heat the bed to 75c, but i really dont understand whats going on.

Never mind. I re-seated the thermistor cable on the electronics PCB and it seems to be reading the temps correctly again(2 test prints worked fine). It looks like maybe the pins sagged/bent a little on the board,so I'll reinforce the connector with some Sugru and all will be well :0)
