Ever since purchasing this printer, I have had an occasional problem with getting an error message stating “Temperature is too low”, the only option is to turn the printer off and restart, sometimes I am able to complete the print while other times I have had to scrap the print/hours and start over. This problem originally occurred maybe once every dozen prints especially higher-temp prints but now seems to happen every other print that requires over an hour print and usually numerous times in the same print. I have replaced the hotend with the Creality replacement kit but still have the same problem.
