Help please. Dip switches and mach 3 settings

P.S. measuring between -12v on the other side of the bob, and the p10 to 15, I get the same readings, measuring the +12 v and p10 to 15 I get 12v into all pins except p13 which has 16v.
Is this the -ve fro the power supply? the - pin of the dc12v?

It seems that you may have a poor earthing of the mains supply. If you get any voltages on the earth from the pole, you may have a bad /corroded connection somewhere outside.

I cannot fix anything out there. I can only disconnect the earth mains wire, and instead add an diy one, like drive an iron rod into the ground somewhere outside. Is this good enough?

An iron rod will corrode quickly, earthing rods are brass or copper.
I don't know how things work in Romania, but in UK Electricity supply safety is taken seriously. I would ask a qualified electrician before doing anything.

Back here the hardware part of electricity supply is from the time of communism, E-on just bought the old national company, but did not upgrade anything, at least not in the village areas. Well, they.re still changing the main fuse/clock boxes at some houses today, as there still are properties with ceramic fuses.

So if you.re nostalgic and what to see how was life in the Uk 50 years ago, come over. Maybe even longer than that.
We have some spanish family friends which visit us now and then and they always point out activities going on here, which were present in their country in the 70.s.
The whole eastern block is like this, but slowly we.re catching up. Looking forward another half century, you.ll be able to drive a car here, while being sick of the spaceships you.ll have in uk.

Now back to the problem, if the issue is inside my property, I assume an electrician could change some cables and so on, but they.ll not change the whole electrical infrastructure for me. :)
I doubt that the problem in on my side, as the whole residential wiring was done 3 years ago brand new.
I.ll ask anyway to see, maybe he has some kind of solution.

I.ll post a video very soon with some axis movements to see what you think.

Sure Andrei, I have this feeling that the problem is a poor earth connection outside the house. If you get a voltage on the earth wire when it rains, then that would give you a 'tingle'. Putting an earth rod in would sort that out I am sure, but whether it should be connected to your supply earth in your case is something I would take advice on as there may be a problem with leakage currents.

I have a feeling that this earthing problem is the root of the strange behavior of your CNC machine as instead of putting an electromagnetic calm around your equipment, it would be doing just the opposite.

I appreciate the legacy of communism will be slow to remove, but at least progress is being made.
