hi, i had built a 3d printer like the ultimaker not the same but very similar, i having some troubles with high detail printing, i had all my axes squared, i chekit with a micrometer and with a 90 degree steel angle rectified with cnc, so no chance to be mechanical problem, i had a bowden extruder setup, i had printing some pices and the quality is very good with a litte stringin/ooze, and yes i double checked the e step, i had 195 steps per mm with a mk5 gear or mk8 i dont remember what gear i had, but when i try for example print this file

i suffer extreme oozing/stringin, i dont know why, but the piramid and the circle and the overhangs appears to be good but the stringin is so much that ruins all the print, i am using slic3r, and when i activate retraction it dosent generate any retraction in the g code, some times do something like this
g92 e0
g1 e1.0000
bla bla bla
and its strange becouse i put in retraction 1mm, the stringing get worse, later i change the e1.0000 for e-1.0000 ,and i get problems of under-extrusion, and when i put in the slic3r the option of do extra extrude after a retraction it generate code very hard to understand, and in any place generate extrusion with negative value, even with the retract after layer change is on, and i havent see any gcode comand that do retract.
I dont know if its the slicer, i didnt try cura.
i tried lowering the extrusion temperature and no change, i am printing at 185 with a e3d hot end and 60 degress in the heatbed, and yes i also chek that the bed is leveled
