Personally i just use the Limit overide inside Mach. But if you want an override then just wire a Momentry button in the circuit (don't use a Switch). Only time i use an Override button is if the Limits are wired in the Safety circuit and knockout Power Etc Which I don't do any more for limits.

I cannot be 100% sure thats where it is coming from but its roughly when the machine hits a certain speed in the middle of the x travel.
Yes but not yet.! Run it slowly for a while and tweak alignment of screws. You'll be surprised how much just little missalignment can make to how machine runs and sounds. Then if it doesn't go away then think about stripping down after a few weeks when things have settled down.

Should I expect it to be a bit quicker or is that normal? once up to speed it seems to be fine.
If 10mm pitch screws and drive Micro stepping is 1600 then yes 160 is correct. Safe velocity for testing would be 4 or 5000mm/min with Accelleration of 500-600. With the aim of reaching around 10,000mm/min and 1000-12000s.

Homing is slower and will be a percentage of the Velocity which is set in Homing & limits. Faster you home the less accurate the repeatabilty. 20% is a good figure when at 10mtr/min.
