sounds like the usb connection is a bit slow.
The ideal way IS to print from the sd card directly.

That way, when the slicer or your computer crashes - the print doesn stop.

For up to maybe half hour jobs, the usb is usually fine, but for everything else - use the card.

It looks like the printer is pausing without retraction, while waiting for the next command to process.

If, like me, you find the bloody stupidly tiny micro-sd cards a pita. Get one of these: https://www.amazon.co.uk/LANMU-Exten...s%2C268&sr=8-3
I have them on both my printers that take micro sd cards :-)

But basically it's a communications issue.
do you by any chance have windows 10 ?
