yo, sorry it took a while to post the photos but the site went down on friday and i was away over the weekend. anyway, it turns out that all of the machines I have are 3-axis. here are the indepth photos of one of the R50 machines in Dropbox (the forums won't let me attach multiple files..):

I have one more R50, a smaller CNC miller, and an open CNC miller, that might require the same set-up process as the first R50?

P.S. dropbox is still uploading the images, should be done in 30 minutes.
