Trying to print with TPU and I'm setting the nozzle temp to 230 while the bed is 60. However, whenever I send the data to the printer the nozzle temp falls down to 175 and the bed temp doesn't even heat up and stays at 0. What's weird is that this is a random problem that randomly came up out of no where. I was able to print a TPU benchy just fine, but now Cura is giving me a hard time! What am I doing wrong?
