Wow, thanks for the prompt reply!
I have the Deluxe Eggbot, purchased about a month or so ago (Santa got it for me, so I’m not sure of the exact date.) I can’t see any checkmark near the screw terminals. The EBB is screened version 2.3.
I’ve just now interrupted a print by deliberately pressing the PRG button – worked as expected. I’ve also now, after finishing a print, pressed PRG several times. It sounds normal to my ears – a slight clean sound of contact being made, and feels normal to my fingers – a slight snap action. (I am an electrical engineer by trade, so I think I have a pretty good feel for these things.)
Now that I’ve tweaked the switch, I will take no further action unless the problem continues to occur.
Now that I know that my unit’s behavior is not normal, I think before I do any sending EBB back, that I will poke around the switch contacts with a scope – see if I find any unusual noise. I am familiar with the PIC 18F46J50, having designed my own board using it, and having programmed it. So…I’ll take a look around and see what I see.
It’ll likely be a couple of days before I have a chance to do this – should I just reply to this thread when I’ve had my look-see?
