Bed printing temperature?

Hello everyone,

To begin with, best wishes!

I have a question, my build plate on my X1 goes up to 70°C with PLA, is this normal, as it seems to me it must be 55°C?

Thank you for your reply.

Then change it to 55°C.
I usually print PLA at 60°C on the PEI sheet.

Thank you for your answer, I just did it… But why does it rise to 70 when at the start, it is at 55°C, I find the delta enormous… if it took 3 or 5 degrees, I would understand, but now?

I am having the same problem except I have been printing for a year now and this one just started
