Everytime when im printing so far, the printer loses connection to the mcu. I’ve change the usb and added a ferrite core to both the pi 4 power supply and to the usb. Tried the print again and it got further this time but still lost connection.
I’m hoping someone can assist me with this as im at a loss.
I See this error in the file…
