It is from bugfix. I just changed the version manually due to some quirks i get with flashing identical versions . And yes, I was testing the pull to see if it helped. But the bug remains even in the pure bugfix version and I haven't been able to narrow it down. The changes in the Configs is near identical though, but if you like I can provide them again. The original used all defaults for FT_MOTION section.

The build does work fine if I use the LCD menu to disable FT_MOTION and restart. There is no other branch here beyond your pull request. Only changed values.

I'm about to run another debug build and see what I can find. The simplest explanation (to me) would be that the triggers are being inverted, since that would explain it happening on all axis. For the life of me I cannot see anywhere that would be happening.

@bmourit , please post your config files for bugfix. It's look like a buffer issue ( buffers too large).

I believe you are correct! Feel free to close this. I'll open a new bug if I find it again, but this seems to have been the issue. Thanks so much!
