Having trouble with converting to G.Code files from STL etc? Sometimes they turn out fine. ( twice ) i am a Newbie.. Ive tried a couple programs, the Tugboat and Rabbit that comes with my V2-3 Neo I think off hand regardless prints the ones that came with printer fine ? Why am im having such trouble ? I tried a cookie fidget toy, it works but the gear itself looks way too large?.. I thought i shouldn’t. Have to change parameters to make it larger or smaller? This gear i printed was 3X the size it should be ?? Any tips thanks
