Printer not reading .stl files on SD card and printing using USB cord.

Recommended Posts

Hi All,

New to this forum so excuse my ignorance of forum rules and regulations, etc. Sorry!

I am having trouble transferring files to my SD card to then print. I am using the Ultimaker 2 Extended. I also am not able to print via USB. I've read that USB is not ideal but for some reason my printer isn't registering in CURA. Every time I hit print nothing happens. As far as the SD card goes, I have loaded several .stl files onto the card but when I plug it into the printer it does not read the .stl files. Any help/advice would be much appreciated as this is for school. Thanks!

You want to transfer gcode files, not stl files. stl files need to be sliced - you have to specify how thick to make the slices, what nozzle size you have, things like that. After cura slices your stl file make sure you look at it in layer view - this is a crucial step as this is where you find all kinds of problems in seconds rather than hours of printing. Look at every layer even if only for 1/10 of a second - you can use shift-up arrow and shift+down arrow to scroll through the layers quickly.

Then save to a gcode file and copy *that* file to the sd card. Good luck.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
