I have a P1S. The unit on the left is the Bambu unit. The unit on the right is the 3rd party unit. I should have removed the rubber sleeve from the assembly; there is already a heater and thermistor attached. I could not find the type of connector on on the bambu unit – maybe it is proprietary.
I see those aftermarket hotend assemblies all over the web, but I have not been able to find how to connect the cables to my P1S.
