Thank you for your suggestion, I will do some tests with lowered current.
As a suggestion/feature request: How about a command to (de)activate all power management until the next command? This way I could just issue this command right after having finished milling one piece. As soon as I would issue the commands to continue with the next one, the usual settings would kick back in and reactivate it.
My problem with the timeout solution is, that I have to change tools (graver, drills, …) while having to maintain the exact same position – 0.1mm difference could be too much already. I think this shouldn’t really be a problem with switched off steppers, but I also wouldn’t have thought I would have the problem while milling 😉
