Just updated to V5.24 on my NEMA34 Pro machine.
During homing the Y2 (right) motor makes a “thunk” just at the end of the sequence as it’s micro-tuning the alignment.
I understand there’s been some improvements made to the homing process.
Any insight so I can fix this?
Thanks
That’s normal. It’s the gantry squaring itself.
Huh… it didn’t do that before the upgrade.
Guess my concern is that I associate this sort of “mini-crash-like” noise with wear on the transmission components over the long run - but my imagination tends to exaggerate these things tho 
Nothing to worry about. It does that sometimes when it disengages and reengages the Y2 motor.
It might be a good time to square your machine if you haven’t already
Was thinking the same thing…
Thanks Eric!
FWIW, mine does the same thing – a thunk at the end of homing (stepper motors), and it was new after the prior upgrade (5.22 I think). I figure it is okay, but I never looked into what was really happening.
Depending on how the macro decides it needs to square your gantry it may lock or unlock your Y2 stepper. Sometimes when that happens there’s a bit of a thunk.
