... and once again @dc42 has fulfilled the picture of an electronics wizard that I have of him:
(no, I cannot draw at all, this was generated with hotpot.ai art-generator, and I could not get that stupid KI to make the PCB larger)
Three prints up to over 6mm without filament and one with filament, all with Input shaping enabled - and not a single "bang" or layer shift! For the first time ever!
Congratulations, Sir!
As far as I can tell, it seems you have solved the issue!! THANK YOU!
Now I guess I can finally throw all these away
(By the way, the larger blob is still there, however not in the first affected layer but in the other two for some reason. But now the printer simply runs over it, so this is a minor annoyance now and nothing more. I will check if including the retract/unretract command into the print file instead of letting it the Duet do has an effect or such. In case I find something, I will open a new thread for that)
Edit: @adrian @oliof Please also write here if the current version solves the issue for you, then I would mark this as solved
