Jay go here http://www.soliforum.com/ I had about 90% of my questions answered at this Forum. Also I recommend going here to get going on your DaVinci Jr. https://www.youtube.com/watch?v=NQh1Jm1DKF4

I have a DaVinci 1.0a and it works great!

Hector

thanks. I did want the 1.0a, but it was just out fo my price range

The main thing is to look up the sites, ask questions and go for it.. You will "get hooked" and have fun. Buy some more filament and start printing.

There are many EZB 3d files which you can print. Get the simple ones to start. Also get use to your machine, and be patient. I write down my settings so I can watch my progress.

Let us know what you are using for software.

well, as im using davinci jr, im using standard XYZware. Didnt know any others would work

Just checking .. Ok .. You asked about scaling issue. Is that resolved? Also you are using PLA, Right?

Ron R

yah pla. Well, i printed out the lever and it just seems a little small, plus the it wouldnt fit onto the part where the servo horn usually goes. TRied to force it but had no luck.

Some printers have a bit of accuracy difference - which can be a little frustrating at times. This is where a hand file comes in handy

Also the direction that is printed on the print bed also matters. If it is aligned horizontal or vertical. Oh, and the resolution that it is printed at. The resolutions are displayed for each 3d printable part in the ez-robot library.

And lastly, the type of servo that is being used may have a different horn size. All the parts are designed around the ez-robot HD servos, which have the same horn size between HD and Micro.

To add to what @DJ mentioned, the size needed is a 25 tooth servo output gear, that's what the ezrobot servos are.
