Hi. I have a Robo R2, and I have started the process of adding a second extruder. After a few bumps in the road, I finally bought a new extruder and got my Robo R2 to list the second one. I plugged it in and noticed an issue. The second extruder read as 0.0*C. Is there any way I can fix this? I obviously can’t 3D print with this extruder without the printer reading the temperature. Please help!
