I received my Hi combo. After assembly, I have received many errors. The Hi printer cannot print using the CFS. I did an online chat, listed the errors and explained the problem 3 days ago. I was told they would create a high priority ticket for the Techs. I have heard nothing back from anyone. I have a $600 paperweight on my desk. I am so upset right now that all I want is for someone from Creality to contact me with information on returning this printer at Creality's expense for a full refund. Anyone know where I can contact someone at Creality where I will actually get a response? I am so disappointed but am not going to spend another minute dealing with this printer. I just need to return it and I'll spend my money elsewhere.
