Fitted my Smoothstepper last weekend, fluffed about for a little this past week trying to get other things sorted but tonight I tried some a small engraving job in aluminum. Oh WOW what a difference, the corners are now corners not a rounded representation of one. My machine now cuts a circle, not an oval. Very happy.

The only thing I borked on was getting the 26 pin header back to front and wondering why it was not working. DOH!
