This is a new problem. I've tried everything I can think of.
I've cleaned the nozzle with acetone even,
I've went so far as to replace my extruder motor, taken my Titan Aero apart and deep cleaned, put the silicone jakcet back on, voltage for the stepper is set at about .64, and it's not overheating, I even replaced my thermistor thinking that perhaps the temperature was dropping during print?
It will print great for a little while then jam near the end of the print, around the same time. I've checked the file in my slicer, I use simplify3d and there is nothing strange during the end of the print. But it does this with all prints...
My retraction is set to 1mm, but I've tested going lower and the same thing happens.
