Printrbots are susceptible to ESD

I found out purely by accident that the printers are susceptible to static shock. This also seems to imply they are not U/L compliant.

For whatever reason, I had been picking up a lot of static today (humidity/wind/weather?)

And when I walked up to the machine that was printing my object I rested my wrist on the aluminimum strip that goes horizontally right by the laptop. I got a static shock and the printer stopped printing, and the laptop lost connection to it.

I turned the printer off then on, and disconnect/connect in the software and all was well again.

This happened on Righty.

Printrbot might want to look into this to make the printers grounded or what have you.

Are talking about the PolyPrinters?

They are aware of the issues… Polyprinter found out 2 years ago.

2 years eh? lol. Well, perhaps some tape across the metal would fix it.

They are normally relatively tolerant of static (since improving the
case grounding way back) so we’ll see if that printer’s hinge or frame
is not static-grounded correctly.
