Description
Issue Details
Due to design of the E3 Mini/Turbo, V4.2.2, and V4.2.7 boards suffer from EMI on the LCD lines. This presents itself as if the LCD button is being pressed repeatedly or the feedrate on the LCD (the 100% changing) changing on its own. This is most common on the Ender 5 series machines. This is not a firmware issue; this is an issue with the board itself.

Giving a 3 star as I am on the fence with this product. 3 chokes at the LCD end are not really doing a lot more than adding a ferrite bead to the LCD cable. Great if it works for you, all power, but I noticed no difference, and honestly out of my 10 ender printers, 5 with SKR boards, 5 with 4.2.2 Creality boards, I only had an issue with interference on 1 printer. So that’s 9 out of 10 that had no issues at all. I did try this add on, but it made no difference. I think most people that have issues with the display and encoder are going to have faulty mainboards more often than EMI issues.
My background is electronics engineering, and although the devices out of China are minimal with filtering, the Biqu (BigTreeTech) boards are actually well designed. Creality a little less so, but the issue of EMI is not as big as people make out
