For some reason I keep getting temperature fails on my R1+. The printer goes off, and then slowly it comes back on. It went from dependable printer to this overnight. I did a PID adjustment in the config.h and it still failed. I was using Octoprint and I can see from the graph, there was no temperature drop from either the bed or the hot-end. I have no idea what to check next. I do have this running in the shop in my basement, and this is the first year I have my print farm and it is colder down here. Could it be the cooler room temperature? None of my other printers are doing this.
