Well. I finally got rid of all the following errors. Thank you! Here's the first video of the lathe cutting a lobe. https://www.youtube.com/watch?v=KzEPyKZ6Xjo&feature=youtu.be
This is the first test so I'm sure I can get more speed from the X axis and spindle next time I test. Also, I'm taking not a very deep cut because the tool has not enough relief so... that's it for now.
