Hi guys. So I was trying to print something for my project this morning. I load a new gcode file on the thumb drive and load it into Ultimaker 3. Once it finished leveling and started to print, I noticed that it became dotted lines. I don't know how to describe it but I've attached pictures for you guys to take a look at. Did you guys ever encounter something like this before? If you have any idea on how to fix this, help a bro in need.
