That's the most common sign of EMI, It should help.
Something that is noteworthy is my display has never freaked out, but the machine still exhibited corruption.
Well, no chokes in the mail yet, and I printed the model off and a second one for a total of 13 hours with no problems, it is most likely the model I sliced broke off at some point and jammed the print head, causing a skipped step- since at exactly the same spot, I found a broken piece laying within the print, fortunately with some blue-tac I put the piece back in the support and finished the print.
I absolutely hate built-in supports- I had to put in .1mm horizontal expansion to compensate for the void in supports.
Still installing the chokes when they show up, never hurts to be too careful, and Murphy loves to strike when you least expect it.
