Hi @metabs
Try Facebook groups and search Thingiverse goups for Pursa i3 there should be updated settings for your machine. (the new settings should give you very good results, also tighten everything check the bolts screws and nuts)
And you could also look into new Slicer software. (Cura is not that good compared to Simplify3D)
Thanks for the recommendation. I learnt everything I know from forum based communities and I share your view that it is probably the best way to keep the printer running properly and continue learning
