Here’s a good one for you guys to have a guess at. I went to turn on the cooling fan from the LCD just to make the fan run a little bit, about 50. As soon as I pushed the encoder button everything stopped mid print and the extruder motor ran in reverse at max velocity until I shut the machine off. How’s that for a static bug!? I had also noticed the static issue before a couple of times but I haven’t talked about it because I haven’t been able to figure out a fix yet.
I’m thinking some well placed decoupling caps can suck up some of the extra electrons that are accumulating.
If any of you that have this happening all the time have a good volt meter with a min max setting you can place the black lead on earth and touch the red and pick up the potential. Fish around and find where the static potential is the highest. That’s what I’ve been trying to do but can never quite catch a spark.
If I were to guess I would bet it’s either coming from the steppers–magnets can push a lot of electrons around in other places–or more likely at the nozzle where there is a bare wire touching the block and lots of plastic is rubbing across a metal surface.
