torronterasktm

thanks, A few days ago I installed the 3.7 and print perfectly, I dont know what could happen with the 4.0 because I installed it three times and it was not solved

I did a factory reset after updating and then updated by USB but it was not fixed, what I want is to go back to version 3.7 because in another ultimaker 3 that I have has version 3.7 and prints fantastic

since updating the printer prints very bad, using PLA and the contour of the piece is wavy, as if the layers were not aligned and I want to know how to return to the previous firmware that if I'm not wrong is the 3.6 ..., help please
