While I am working to use the stock heating element, the goal of this is to be able to swap this heater with another if you don’t want to spend the money on the oem unit or its not available anymore at the time your reading this.
The circuit board is going to be looking for all these connection points before its going to let you turn the heater on. I will verify this for sure later but I assume with the danger that comes with heaters that bambu build in a lot of safety.
With that being said. It would be nice to be able to repair these units or swap / upgrade them if better becomes available so figuring out what types of probes are used I am sure will help us achieve whatever we want to do.
As you can see here. there are 2 temp probes here.
and another prob here.
