Topic: AZTEEG/ negative wire from power supply to be grounded?
With an AZTEEG X3 PRO, should the negative wire from the power supply be grounded to the chassis?

The green wire from the power supply on the AC side should be connected to chassis but the same should be achieved through the screws that mount the supply to the printers frame. The chassis should be at earth ground, not system ground.
Many thanks, that sounds reasonable.
We were told to "not to ground the board to the chassis", does that make sense to you?
We were also told that splitting the ground plane up (within the X3 PRO) by adding a ground, separate to the line ground, is not a good thing to do. Do you agree?

When dealing with anything powered by AC mains which has metal parts the user can come into contact with those parts should be tied to earth ground which is the usually the green line t hat is connected on the supplies AC side.
The board is powered by DC. It does not and should not be on the same ground reference as the Earth or DC ground. The DC ground is tied to the Earth ground indirectly through a 1K resistor inside the power supply usually so no do not ground the board to the frame except through the standoffs which the board mounts on naturally.
Many thanks. Let me think about that for a bit. Valuable info.

This is in case there is a short or other circumstance that gives the AC a path to the metal parts it will by carried to Earth ground and not the user.
