SD card - reads folders but the the STL's

Recommended Posts

I finally got my SD reader and finished building my ulti controller...

everything works fine now, and the card is recognised when i put the card in and get "card menu" etc etc etc

now i see folders inside my SD card, but i don't see any STL's

umm - err - ???

I'm almost certain the controller can read STL files and feel daft asking that question... what else could it be. It is a 2gb SD (standard) Fat32

The printer only needs the G-code, it has no idea what an STL is.

Also, when the card is inserted in your computer there should be an "SD" button in the 3D window at the top, that's a short cut to save the file to the card. Note that it will use the same filename as the stl and will overwrite any other G-code file on the card with the same name.

STL files describe the geometry of your model. So how it "looks".

GCode files describe how the printer should move to produce this actual model, and how much material to put where.

Going from STL to GCode is a complex process (usually called "slicing", but I rather call it "processing", as slicing is actually only 1 of the steps you need to do)

This process needs to be done on a PC, and currently cannot be done on the printer, due to the large amount of processing and memory requirements.

Cura does this STL->GCode conversion for you. The Cura manual should help you here: https://www.ultimaker.com/pages/support/manuals

Thanks for you advice this is know complete.

I am missing the different % i can set for my printing as i usually have
