CT2015

Tried as you recommended...still did not work. Took my computer down and had all the USB ports checked, everything is normal. Bought a new cable, just in case. Just finished running through the whole thing again and still have the same issue. Frustrated....

I'm using the SD card that came with the Ultimaker 2 which came with several files that work fine when printing. I've down loaded a couple of files from YouMachine. Ran the file through slice set for Ultimaker 2 then saved to SD. The new files don't shown up on the Ultimaker 2 screen where it allows me to select which program to run. The files that came on the SD from the factory are dated Feb 2014. That lead me to believe that the firmware might need to be updated since I'm running Cura 15.02.1 and since it appears that have been some recent updates released. I'm not able to run update for firmware because Cura returns a message telling me to plug the cable into the Ultimaker 2 even though it is plugged in and the printer is on. I've had the cable checked through my IT dept. who are telling me they don't see a problem with the cable. I've tried plugging in to the (3) USB ports, but no luck. Could the antivirus block this type of connection? Thanks for you help!!!

No I downloaded from website. I didn't see anything that said to install arduino driver.

Hi, Cura does not recognize cable connection from pc to UM2 and keeps telling me to connect cable. I have checked USB ports and had cable checked. What should I do next? This started because my UM2 will not recognize new files that I have generated in Cura to print. However it does recognize the files that came with the printer. These files are dated early to mid 2014 so I thought maybe it was just a matter of updating the software. The machine is new, just received it 1 week ago and have not had any problems printing from the files provided on the san disk. Help! Thanks, CT
