Hi , one interesting comparing test with Ender 6. Creality Cura 4.8 based Slicer vs Creality Cloud Wifi box slicing. Material: PLA+ , all the same settings its most possible , Creality Cloud Slicer have bultin ironing function - the finish result is amazing. Longer LK4 Pro - all the same settings in the Cura 4.8- (i'm not shure was the ironing ON, most possible) Ender 6 with Cura slicer without ironing- bad-ugly finish. The Ender 6 with WifiBox - Cloud slicer have the best finish, layer and the arc perfect, top layer perfect, ....by Longer - defective top layer, the arc is not to smooth.... The model is one Ant Trap ....
