As I built this hot end the more I built the more I have become worried. if I have to service it to replace the theorister or the heater slug. That will be a major day of work. the screws that clamp the heater slug are facing up and unless you take the control board off you can not loosen these screws oh wait the board has wiring attached It's not going to move + all the elect. parts are soldered in. on my Robo R1 the hot end comes out by unclipping two wires and loosening one screw then move a swing out holder and the hot end is out . if you wanted to change the temp. wiring heater or Temp Gage. You can do that with the unit still in the printer. I bought this printer because when I saw it work it was great . I just don't know about the way this hot end is built it might be ok but right now I am unsure about how it will operate.
