Describe your issue:
…I am constantly getting loss of comm with MCU. I do get some prints that finish and its random disconnect it seems. I have attached USB to board direct and glued. I have tried a Creality Sonic pad/ Pi 3b/ and now the pi 4.
I have tried adjusting baud rate also.
I am at a lost and not sure anymore.
