Unstable Nozzle Temp

I've noticed that my nozzle temperature will occasionally jump around crazy during the start of a print. I am printing in PLA at 210C, but the nozzle will drop to 205 then shoot up to 212 and will flux.

What would cause this, loose cables on the print head?

check if all your cables on top of the print head are secure: the thin ones going into the green block and the white connectors. Sometimes they can get a bit loose because of the motion. And separate the fan wires as much as possible from the rest.

      "Back To The Future" using Generative Design & Investment Casting

      SteveCox3D posted a topic in Engineering,

      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
