[rosagreenberg]

I got my ender 3 v3 SE today. I've done all calibrating stuff but I don't know what slicer software i should go w/ ? should go w/ default slicer of creality or try some other? Also where should I download firmware inside pc or printer? pardon me but I'm really new to this 3D print stuff. Learning on the go..

You need to download whatever slicer you want to use onto your PC.

Import any files you want to print into the slicer which will convert them into a G-code file that your printer can read.

Export the G-code files onto a USB stick or SD card, whichever your printer uses.
