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.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
