I recently put an OG E3D hot end on my Fystec prusa clone. I was having issues with the thermistor hitting MAXTEMP which led to getting a replacement. I’m still having the same issues. Swapped to the fulystec parts to which I started getting heating discrepancy. I have been in contact with E3D and they can’t figure it out. I’ve done everything they recommended and concluded I need to get another replacement… any thoughts? Is there an issue with the Fystec Rambo board? I could see one thermistor failing but 2 back to back? I’m really frustrated because I love this printer.
Thanks in advance!
