I am thinking about rewiring the extruder heater cartridge. What is the connector on the Rambo Mini? I'm thinking about putting a similar connector close to the extruder to make replacement easy. I tried looking through the schematic but could find the part number for the connector (I believe on page 4?).
This is referred to as a Terminal Block Connector. More specifically this is a 2-position pluggable terminal block connector commonly manufactured by Phoenix Contact and others.
