Hi friends!
Have you ever seen a temperatures graph like this? Hotend and Bed are not being powered, it just oscillates like this at room temperature.
Don’t know what to check, 
electrical interference maybe?. Any help is welcome!

What thermistors are used and how is everything connected?
The custom printer implies potential issues.
Hi there, it’s a PT1000 on a Goliath Hotend, and the bed is a Keenovo thermistor.
Everything is grounded,
I tried 3x pt1000, all with same results. the strange part is that all temperature sensor oscillate.
i can give more info if it helps you help me, what should i check?
Thank you for the reply
What exactly is grounded?
Is this an AC bed with SSR?
Is both oscillating if only one is connected at a time?
