Now, for some unknown reason the machine is 'knocking' inside the Lower arm of the machine when I sew! 

Did this happen on its own, without any new user action, or as a consequence of another adjustment? If an adjustment, what was it?

This happened on it's own.

I was sewing 2 pieces of leather, back to back, on a 20" run, made the turn, and was heading back the other way when it started knocking really loudly.  I can feel the vibration in my foot on the pedal.

 

I spoke to Springfield Leather this morning, and they can't figure out what's going on with it either.  This particular machine has less than 2 hours on it at this time, and we're beginning to wonder if I didn't get a lemon. 

 

If I had more hours on the machine, I would think something was out of adjustment from use, but this is a brand new machine that I just recently switched to after selling my cowboy.

Sounds like a screw has loosened up.

I checked all of the screws with Springfield this morning on the phone.  It's not a loose screw.  I'm sending it back to them.

I had already spoken to them, and they couldn't figure it out! 

 

I have a new machine now.  Hopefully it's dialed in.
