[3.6.0.Beta.2+4] G30 Z motion max accel not enforced
-
It looks like something related to probing speeds might have broken in Beta2+4
The first homing process from a fresh restart works completely normally. but subsequent homing procedures appear to either have the wrong accelerations or max speed applied.
Sending G30 on its own seems to be completely fine and doesn't replicate the issue.I have made a YouTube Video showing the behaviour by pressing the Quick Home macro x3 times from a cold boot

@Notepad thanks for providing the video. What was the last version you ran that did not have this issue?
PS - instead of reducing XY acceleration using M201 and then restoring it, you can use M201.1.
