I've recently completed assembly of an AnyCubic Prusa clone. It's working, but having some issues. My prime concern at this point is the LCD display. It occasionally becomes "corrupted" for want of a better term (see image) and no longer responds to the control. It's done this unattended in the middle of a print attempt, which means I can't pause it to remove the imminently dripping filament from the leaking extruder (another issue I'm dealing with).
So three questions I guess...
Is this a typical problem?
What's the likely culprit (main board, display, firmware)?
How to fix it?
I'm working with AnyCubic's tech support, such as it is, and wondering if I need to push them for replacement hardware. Thanks!
