Hi, I'm looking for a solution to connect Cura 3.0.4 to my printer. I'm still using the 15.04.6 version because it's the last version I was able to connect to the printer, every versions between were not able even to find the printer. On version 3.0.4 it's sligthly different the program "sees" the machine on COM3 but when I launch a print nothing happens. Does anybody has an idea? I know that some of you will tell me to use an USB stick but I have two other printers connected on my computer and those ones don't have any slot, so it's a kind of an habit to work that way. I even didn't try that way.
