I just installed my second toolboard for the IDEX but whenever my heater gets to 245c I get a heater fault. It'll hold at 240 with no issues. I managed to pid tune it to 250 but then it'll go right back to faulting at 245. It's the Phaetus Rapido 2 with a pt1000. I'm not sure where to start. The wireing seems fine and like I said it works fine up to 240 and it will pid tune to 250
