There is another thread about it from earlier.
Mine was defective, so I waited until I was going to order something else from Bambu to order the spare heating element and thermistor.
I don’t know if the heating element in the V3 is different than the factory Bambu heating element. However, it seems to work fine with the Bambu replacement parts. I haven’t done a flow rate test yet, but it seems to print fine with the 0.6 nozzle.
