Kent, You got it in one. What confused me is that the example program runs out of the box in the axis_mm configuration... And no, I did not read the code since I'm only trying to turn the crank and not try to figure out what the program is doing. So, I aggree with your rant. If you wanted to use this as a teaching moment then it would be better to, and Kent notes, have it in a tutorial, or set up a separate configuration tree to teach specific issues (like toughing off, and what can happen when you don't). As a note, it was my understanding that the examples where supposed to just run out of the box, so I assumed that it was a bug in LinuxCNC. It also seems like I am not the only one to get tripped up by this... EBo -- ps: thanks Kent for the intuition. ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
