      Hello to everybody,
      I just bought several Railcore II 300ZLT.
      I am having some problems with the hotend temperature.
      1/ The T° is programmed for 220°. When I don't turn on the fan, the T° goes up and stops.
      2/ when I put the fan, the T° goes up to 220° and stabilizes.
      3/ As soon as I start printing, the T° goes up to 220° the fan cuts off and the T° exceeds 235° and stops.
      I can't resume another print or restart the T°.
      I have to turn off the printer and restart, to be able to raise the T°.
      4/ When I start the printing and put the fan, the T° arrives at 220°, then the fan is cut. The T° rises and I put the fan back on. The T° stabilizes at 220° and the printing can be done.
      Do you have any idea how to avoid this problem?
      Thanks in advance.
