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:
