Don't forget your software upgrade’s

Whilst trying to print the planets  for the tiny planetary gear set I found that they would not fill correctly, after reading on this people were suggesting that the extra shells settings were the cause after much fiddling to no avail I finally got the impression (again from more reading) that maybe there was a fault with the software so I bit the bullet and did a complete update of both Pronterface and SFACT to the latest versions and voila the problem vanished.
