Electric shocks

After a few weeks holiday I came back to print a new project.
Bamboo labs software complained that it needed updating so i updated it to 2.6.0.51.
My latest model didn’t print but the 3d printer printed some old file from weeks ago. I looked it up online and it was suggested that I turn off the printer for 30 seconds and upgrade the firmware. I turned it off. i upgraded the firmware to 1.10.00.00.
Then I got electric shocks form the body of the printer and a message saying the the micro SD need reinserting or replacing. I went to remove the card and got another electric shock from the casing by the micro SD.
Now the printer is off and unplugged and I am waiting to here back from support.

I am quite sad

Most likely static electricity, change your shoes.

Otherwise, wiki has an article on the subject

Definitely NOT static… :high_voltage:
Thanks for the article link :slight_smile:

A software update didn’t compromise the electrical grounding of the machine, and didn’t electrify the chassis. Perhaps is your outlet not grounded correctly, or are the hot and neutral wired in reverse? An electrical outlet tester is a good idea to verify all those things.

Assuming this isn’t static, and your outlets are good, that means your machine has a serious problem, unplug it and get a qualified electrical repair person to look at it.

I agree with @CarbonForge. That’s just not how software updates work. Correlation does not imply causation.

You can get a decent receptacle tester for somewhere around 10 to 20 USD.

Do you get shocked every time you touch the machine? If yes, there is probably a grounding issue. If it doesn’t happen consistently, it is most likely a static issue.

I would take the back panel off and look for damage to the power supply or circuit boards. Then look at the wires and see if there is any damage.

A tingle or shock from the chassis usually points to a grounding issue. It’s worth checking if your wall outlet is properly grounded or if the power cable itself is fully seated. If you have a cheap outlet tester, that’s a quick way to rule out house wiring. Sometimes it’s just static, but if it’s a constant “buzz” or tingle, it’s better to be safe and double-check those connections or try a different power cord before diving into the hardware. Stay safe!

Yeah. The machine’s frame and the metal parts that are connected to it is grounded. If you’re getting tingling when you touch the machine, it’s probably a “ground fault” in your electrical wiring.

You can test this fairly easily if you live in the US, where regulations require GFCI outlets near sources of water (like a bathroom or kitchen). If the machine has a ground fault internally, plugging it in to a GFCI will pop the GFCI breaker immediately. If it’s the outlet you’re plugging the machine in to, the bathroom GFCI won’t trip.

The electric shock from the metal body strongly indicates a grounding/earthing fault or leakage from the power supply. In a properly grounded printer, the chassis should never carry a noticeable voltage. Even a mild shock can indicate faulty PSU insulation, a missing/failed earth connection or an internal short to the chassis. Do not power the printer back on until the electrical issue is sorted out.

Yeah I’m sure it couldn’t have been the updates but it’s weird that it starts happening at that point. I have checked all the cables for the grounding with with a multimeter- All cables and then from the door hinge and SD slot, they’re grounded all the way to the wall socket. I got the shock from the SD slot twice and once from the back of the machine when I went to turn it off. I’m going to turn it back on again and try to see what the voltage is as some point tomorrow.

While you were gone was the printer off or left on? Do you know of any storms or cars taking out power poles while you were gone? Any chance you had a wire insulation loving mouse house sit?

For sure let us know what you come up with.

Just tested with multimeter and get no readings. The printer had been left on while I was away for a couple of weeks. I don’t know if there were any surges or storms.. I don’t think so as the alarm is usually the first to respond. I only have a fried SD card

Thanks for the quick update. Is this a P1P or a P1S or newer. When SD cards are failing they will generally go into read only mode but usually not read/write fail (could be a generic error I guess and not totally accurate) and definetly not cause shocks.

Just to isolate things you might try disconnecting the AMS from the printer (your screen shot makes it look like one is attached unless I am reading it wrong).

yes I have the AMS attached( but not using its own powersource) its a P1S . Ill get a couple of new SD cards tomorrow and try it again

OK. Be sure and lets us know, even if the shock problem seems to go away on it’s own, otherwise we might wonder if you are laying on the floor! You probably already did but with it unplugged check the power cable really well looking for any nicks or abrasions.

If you have an electric plug tester around the house, it might be a good idea to check this outlet for ground/neutral problems, to remove that possibility. If you think the outlet is providing bad power its probably time to call an electrician, it might not be obvious where its happening in the house circuits. Be very careful, as everyone here is quick to point out, magic pixies from mains will kill you

Any other bad signs? Charges/zaps from the plumbing?

Good point on the plumbing. Tingles from plumbing (non-PEX/Plastic plumbing) can indicate house ground failure/problems.
