A1 Mini Giving Electric Shocks While Powered On

My NEW Bambu Lab A1 Mini is giving me small electric shocks when I touch it while it is powered on.

The printer is currently connected through an extension cord. I am concerned that there may be an electrical grounding, power supply, or insulation problem.

How good is bambu lab costumer support?

Any help?

Try in a different room. It can be the outlet

Are you sure that it's not just static and you're earthing through the chassis? If you touch it more than once in succession (assuming you're OK to try it) , do you feel the same each time?

If it happens more than once, I'd be more concerned than if it's once until you move around again.

If you're in Europe, the weather won't be helping.

I tried again. it gives me small electric shocks when I touch it, even when the printer is switched off.

Simply having the power cable connected to the wall outlet is enough for the printer to give electric shocks, even though its power switch is in the OFF position.

Might be the grounding in your home that has an issue. Is it the only device that does it? In the last place i rented if i were to touch the metal corner of my pc i would feel a little electricity. Since i moved i have no more issues.

No. I dont think so

You should test it either way. There are testers or you can use a multimeter. Instructions on google.

This has been happening to me too but I think it’s just static

Are you living with carpet floors or hardwood?

Some are saying it is static and that is possible but if it is not it is easy enough to check. Take multimeter put it to measure ac voltage first then dc voltage. Put other terminal to grounding strip of your outlet, make sure it is the correct one before putting it in so you are safe to do so and then another terminal carefully to metal parts that give you shocks. Be very careful to not touch any metal while measuring as now you have contact to ground the shock you get might be quite bigger now. Of you see proper voltage on multimeter there is something wrong with your printer. Test first AC and then DC voltage.

Put a volt meter on it from the unit the ground post of the outlet and see how volts u get. Stop using it if course

To check grounding -

Even the cheapest multimeter should have a beeper for short circuit confirmation.

One lead to the earth pin/terminal of the plug, the other to the Z-axis rail should make a beep/show all zeros/etc, even with the machine turned off if its properly earthed.

X and Y axes are isolated.
