I am running with PLA @ 200 right now with the bed @ 60. I do have it set to have the bed at 65 for the first layer for better adherence, but after that it is set to stay 60. While I was watching it (was a short print time haha) I never notice the temp change from + or - 2 degrees at most.
If it helps any I am using 3mm PLA with a j-head with a .35mm nozzle.
