I am trying to run dual fans for cooling the print while printing and now my hot end will run at exactly 3C lower temp than what it is set at. No matter what temp i set it to it will hold at 3C below the set temp. I am using Sprinter but im not sure what PID settings to adjust to get it to work right.
Also i noticed my prints look like the extrusion width is to small now and the perimeters and infill arent always touching. Do i just need to adjust my extruder to print more material or this a sign that i am over cooling the prints?
