Printer Grounding – How to Check and Grounding Your Bed
Our friend over at Teaching Tech made a great video about adding grounding to your 3D printer. Those with AC beds definitely should have this and ones with DC beds will benefit from it if you are getting odd issues with your ABL sensor.
Starting at 3:41 this is a great example of checking the grounding on your printer and adding a ground strap to the printer bed. Proper grounding not only helps fix issues with EZABL sensors but also makes the printer safer should there be a short.
