Anyone changed the 2in1out hotend with a 2in2out by using 2 heating cartridge ?
The hotend PCB doesn't have support for a second heating cartridge, but the motherboard does.
Where can I see the extruder cable pinout to attach the second heating to the motherboard?

Hi.

You can view the layout of the leads on the schematic of your controller board.

You can refer to it:
1.You need to solder the pin for thermistor+heating bar
