I was curious if anyone else has run into tracking issues. I see tracking as a series of tiny dots that string together to make a line on the surface of a profile. Sometimes this is constant and sometimes it comes and goes. Usually I run into this on a Davis-Standars 60MM extruder but only when running certain parts. Usually by dropping the 3rd and 4th barrel zones I can fix this problem, but occasionally I have to dramatically slow down the profile by as much as 3-5 ft/min. Any other recommended solutions?
