Cura profile for prusa Mk3s

Posted · Cura profile for prusa Mk3s

Anyone has a good cura PLA profile for prusa mk3s. Default in all Cura editions are bad, no matter what is changed. Prusaslicer works good, so it is not printer issue.

 

Thanks

    Posted · Cura profile for prusa Mk3s

    I have the MK3S as well as the Ultimaker S5 and I mostly use PrusaSlicer for the Prusa, but occasionally Cura.

     

    I have no clue where the so-called default Prusa MK3S profile came from (my original Cura came from our local makerspace some years ago) but it was UGLY!  I assume that yours may be the same or similar.

     

    The big issue was the printing speed, particularly on the first layers, which is supposed to be slower.  It was MUCH too fast.

     

    I set the initial layer print speed from 30 to 20, the initial layer travel speed from 60 to 30, and the skirt/brim speed from 30 to 20 (for the typical PLA filaments).

     

    Cura usually has nozzle temps a bit lower than PrusaSlicer, but they seem to work acceptably well for me.

     

    With the speed changes, there's very little visual difference between the 20mm test cubes done with PS and with Cura.

     

    Both PS and Cura have their strong and weak points.  Cura, in particular, seems to deal with supports, in general, better than PS.  The 'fuzzy skin' (first in Cura) is better, but the 'ironing' (again, first in Cura) is best described, at least the last time I tried it on the MK3S, as butt-ugly, with the same function in PS being far more visually appealing.
