In this class, all these terms you asked about are pointed out, described, and explained. This is why you're having troubles identifying the Z axis shaft, rotary hook, rotary hook support finger, etc... Melco has two techs out of the Atlanta area where as one might be able to help you. You must also understand that it's not unusual for a tech to be booked up a week or two in advance during seasons such as this. It's a busy time for everyone. So get your call into Melco's tech support as soon as possible in the hopes of scheduling a service call. I hate to be the one to say this but getting something caught in your bobbin area is discussed in the training class and is usually not covered by the warranty. Similar to driving a brand new car off the road and into a fence. Best of luck to you.
