I had trouble with the printer stopping and not feeding filament. I had to hand roll the reel to get the print to complete. I figured it was a problem with something I had done, but the guy printing after me has the same problem. The filament is free in the feed pulley. The filament reel seems suitably free wheeling. It’s not clear to me why it’s stopping, but it is.
I did not have this problem with 91 which I’d routed filament the same way.
The printer is usable but requires very regular attention or it stops until you feed more filament.
