Re: Z home pronterface works, G28 Z0 makes Z movement freeze

Well, I've pretty much given up. I hate this. I've tried a gazillion Marlin settings and today I even replaced the TMC 2130 drivers with basic A4988 drivers. Wrote a fresh new Marlin, uploaded, it all worked. And then it started failing again, first a little bit and it is progressively getting worse. Here is what it did earlier this afternoon:

Now it just freezes when I ask it to home. With Marlin replaced 38945739458 times, all drivers replaced, next on my list is new RAMPS and real (not Chinese copy) Mega. Unless you have any ideas?

Cheers,
