I load a folder using the web interface and then select the ngc file using the computer. When I move to the machine both the folder and ngc file are blank but I can select them. In older versions I was able to set the ncg from the computer. Upload a folder has just created confusion for me. Also screen flicker was not a problem before but now I get frequent screen resets which have not caused a problem with cuts. I understand EMI but nothing changed on my machine, however I will change the brushes on my Mikita.
