I have just set up a Neje Max 4 and all works well except: when homing, all three axes move a few steps in the wrong direction before reversing and moving the right way to the limit switch.
When the toolhead is far from the home position and close to the max values, this causes it to crash.
I’ve never had this behaviour on my other machines. Is there any way to avoid this?

Post here the Console output in a reply?
Also with NEJE Win check if you´re on the latest firmware?

Here post #8 has a material library for Neje.
You didn´t post all the moves.
The only thing worth a try in GRBL settings is:
if $4=0 change to $4=1 (or 3 or 7 depends on your board) or
if $4=1 (or 3 or 7) change to $4=0
After each change disconnect your laser from USB PC and power supply.
Wait 30 seconds reconnect and test.
Report back with results.
