Long print and overheating Ender 3 Max

Posted · Long print and overheating Ender 3 Max

Hello there, we're planning a long press, for 40 hours. Is it manageable for this machine or, for example, is it necessary to give software pause only, etc.? I want to avoid shutting down in the middle of work. Does Cura software have an engine temperature control somewhere? I have no experience with such a long print, so I will be happy for every tip.

    I have an Ender 3 Pro.  My longest prints were back-to-back 27 hour prints and there were no problems.  Any print beyond 20 or 30 minutes has everything on the printer up to it's operating temperature and so a 40 hour print would have the same chance of failing as a 1 hour print.  You could develop a clog in the hot end or skip a tooth on a belt the same as with any print.

    The printer is just reading the Gcode (which should be on an memory card) and there is no monitoring of any system as the only devices to monitor are the two thermistors.

    Depending on how many hours of print time your Ender has; you may want to open the mainboard box and re-tighten the two screws holding the main black and red wires that come in from the power supply.  The wires are tinned with solder (and there are no brass ferrules) and so the connections are prone to loosening and causing a high resistance connection which is a definite hazard.
