I have been trying to get some ABS printing well. I have the E-steps almost perfect. Bed is set to 110deg which seems to be working, extruded temp is 235deg. I have no cooling at any point but seem to get thermal runaways at the around the same place with any print (layer 7-8). Any help would be great. I will have to clean the head up a touch as it got covered in one instance!
