Answered bed temperature behavior

I have the robo 3d r1+ using pla @ 200/bed @60

I just wanted to ask, is it common for the heated bed temperature to rise beyond 60 degrees during a print?
I ask because I've been monitoring a recent print and noticed the temperature spike at 67 and come down back to 60 within a few minutes. I've never noticed this before so I'm not sure if this is normal?

thanks and best to all

 

Thanks, I'll see if this helps me. I noticed my Hotend drifting a little as well. Not sure if it's related to this but I'll see what happens.
Thanks again!
