Help please. Dip switches and mach 3 settings

A few pics with the house to pole supply connection, the main fuse box outside the property from which I get electricity into my workshop.
A big high tension structure which is situated on my property, quite close to the workshop.
It has a lightning protection thing included. Although, I have now and then some fluctuation in the supply, as some light bulbs are blinking/dimming, I never had any appliance broken or anything like that.
Also have a cctv camera in the workshop, a few meters away from the cnc. It does not seem to be affected by the cnc. I don.t know the other way around and might be a different story when I.ll wire the vfd.
There is also the metal control box, with some terminals in the left side, put there only because the terminals on the drivers, due to so much troubleshoot and rewiring seemed to go weak, and so any future fixing, will be done on this new ones.

And here.s a test video for some movement.

It was a lot jerkier a month ago. Not sure how good it is now, though, as all the articles I read say to tune the motors and speeds until they sound good, and honestly I have no idea what this good sound, sounds like.
The settings in motor turning are 800 rev, 600 vel, 50 acc. At this speed, the y axis which is very heavy, seems to shake just a little at an abrupt stop. The other two, could be set to go faster, but as Clive says, one thing at a time.

What do you think?
