I've been having a problem since I upgraded to the EZBoard on my Ender 5. Whenever I start heating the bed, the screen starts beeping randomly like I'm pressing the button. Here's a link to a video clip to illustrate the problem. https://youtu.be/EZsOWSGt670
I did some experimenting and if I just heat the hot end, it doesn't do it. But as soon as I start heating the bed, it does. I can't see anything obviously wrong with my installation and everything is actually working fine. I've printed many multi-hour prints that have come out fine. The only issue happened today when I needed to change filament color and the firmware kept thinking I was clicking the "Purge More" option. Fortunately, I caught it before it got out of hand but there was a nice big blob of filament forming on the build plate and around the hot end.
Anyway, any ideas? Could it be a firmware issue? Hardware issue? Could I have somehow installed something just slightly wrong that might be causing the issue?
