Ok so after calibration cubes here are my two prints with printbot metal. After finding the right temp , the right height of the sensor and replace filament because the previous has humidity i finally print well. But tell me your opinion i hear the nozzle scratcing the item sometimes during the print and i took some pics to see the top of the prints. Shall i go higher? Change flow? Btw the brim are printed well you can see the lines they are not squeezed down and the hold the item. Material pla blue 195c print speed 50 travel 80. 0.2 layer.

What do you use for slicing? I had to set slic3r to raise on retract and to retract (thus raise) on crossing infill too, not just the perimeters.

i use cura for slicing and for printing. I have used cura in my other printes so i trust it better
