RE: MMU2S keeps resetting/Red & Green LED's flashing at once.
...used the new board without any errors so far...
...but...
If I follow the posts and schematics on the github-thread, and if that information is true, it is REALLY an embarassing error by design...
Following the thoughts from there, why would you need a protection for reversed-polarity in our application? I'm seriously entertaining the thought of bridging that diode...
Got to break out my multimeter and do some measurements... 😉
Let me know if you want a guinea pig - I'll happily try it on my old board. Would just need details on what Diode to bridge.
RE:
Hey Sneaks, I absolutely had the same idea of using my old board. Unfortunately the idea just came to mind after I did put out the trash... I you look at the board, the D1 is easily visible. Testing at your own risk though... 😉
So far, I can report that I had no errors so far. Together with the update on the PTFE-connection, I am a happy camper again! Now if only I can get a hold of someone's profiles that claims to have success in printing PVA...
I also posted in this thread here:
Maybe one of thos pro's can break out an oscilloscope to check whether that diode is really needed. Would be cool to know before we find out by bricking our guinea-pigs...

Thanks Daniel! What is this "PTFE-connection" you speak of? I think I must have missed that?
RE:
Sneaks, just to be clear, this is not an official update - though it should be...

That's the 'original', might want to check the remakes if you need different threads for the fittings...

This is AWESOME! Printing now and just ordered PTFE and fittings - Thanks for showing me this!
