There is no doubt about it, PL needs relative strong cooling. ![]() Than stop pushing and heating, the temperature is ok when it is coming out for 1 - 5 cm by gravity /rest pressure The best is to try it out by hand, heat up and open the pulley of the extruder, push the filament through by hand without tools. PLA needs normally 190° +, I'm printing it with 195 °, the derivate from GreenTec is offered with 170 - 220°, it is running very well with 180° (by glass point 120° !) Max 60 mm/s speed don't need it too. try to reduce the extruder temperature. Start Points > set the 1st option, use Random Starts Multiplier 1,05 seams a lot to high for PLA but that is to be tested out, when the filament diameter (Tab Others) is messured very exactly with a micrometer screw I'm using mostly +/- 0,95 for PLA and derivates. With higher speed I have no good experiences, the detachment between nozzle and last layer (just being liquide) is too abrupt and material builds a nobble (see Cooling) Retraction Speed, I have set only 25 mm/s. ![]() Retraction - Restart Distance > -0,15 mm (negativ value!) I have nearly the same machine - conditions with my Mankti, 70 cm Bowden, E3D V6 Full Metal a.s.o.įollowing your FFF file, I would propose to try settings changings:
