I did not see that video, but the certain death of a sewing machine is LINT. Be it a domestic or longarm.........with my dm, I clean it every other day when I am on a piecing marathon, using flannel, everyday, change that needle when I start to hear popping.....On my longarm I oil before each quilt is put up...that means every three days average and when working on a quilt, check and clean out that bobbin area every other row.....it is startling how much damage can be caused by a tiny piece of lint getting in the way of that needle/bobbin doing its job!!!!! Having a regular maintenance routine, is certainly better than spending hours down the road wondering what to do and how did that happen!!!
