My printer works OK when I use the cloud or SD card. I have tried to connect to my PC via USB cable and WIFI. I can see the machine on my router, have all the required addresses to connect by WIFI but will not recognise printer when using Creality Slicer, Using a USB cable to my PC it is the same cable as used on my old printer, which worked OK so doughty cable is faulty. I have tried Simplify 3D and Cura still not connecting. Having trouble uploading my models to the cloud, not slicing. I am gettig very frustrated and considering returning machine and trying another brand.
