[No problem, Bill - it sounds like things are basically working for you, so happy milling!]I'm just getting started with my Taig mill, Gecko controller and Keling steppers. After researching this forum for weeks to educate myself, I've still got several questions.
1) After my system has been powered up for a while, my stepper motors are relatively warm/hot to the touch. This is true even if I haven't been moving the axes. I would expect this a little due to the current that is holding the stepper in position, but I am concerned that they might be warmer than they should be. Is this normal? How warm should they be?
[They can be pretty warm without causing any problems. You are correct that the stepper is using power just holding its position. As long as it doesn't burn your finger when you touch it, I wouldn't worry about it.]
2) I've read countless posts about losing steps. They often mention that you can "hear" that you are losing steps. What exactly should I be listening for?
[The motor will stutter, or growl. When it's happy, the sound is somewhere between "Whirr" and "Zing". When it's not, it will let you know...]
3) There is a "Verify" button on the Mach "MDI" page, but I'm not sure I understand exactly how I use this to determine if I've lost steps. Can someone explain the process?
[I don't think that's what it does; as far as I know, it just checks if the code is possible for it to run (no illegal characters, or out-of-limits moves). I don't think Mach has any mechanism to determine if steps have been lost, although some controllers may close a feedback loop at the drive, and will shut down if the commanded steps versus achieved steps are out of a certain ratio.]
Thanks for any help with these questions!
