  1. OK, I'm going to jump in here and take a stab at this. Even though I do not currently have an APQS machine, this problem may be the same on any stitch-regulated machine that uses o-ring encoders. Since my 2 APQS machines did not have stitch-reglators, I am not sure of the setup. I have had to replace 2 o-rings on my machine. They had a miniscule hole or a crack. I had to use a magnifying glass to see the hole and the crack. One was on the encoder on the carriage and the other was on the encoder on the table. The second time, I replaced the o-ring before I got the random loops. Besides the single loops, I noticed a lack of control. I wanted to go left and the machine resisted. It was so intermittent that it took a while to figure it out. When I finally narrowed it down to the encoder o-ring, I went very slowly until I found where the bad spot was on the o-ring. To me, it was like when you drive very slowly over a pot hole in the road. You feel the tire drop slowly into the hole. And if you don't give it enough gas, the car rolls back into the hole. The machine would actually roll back into that hole. I could feel it on my handles. I couldn't see the hole until I removed the o-ring and used a magnifying glass. Then it appeared like a tiny pin hole on the edge of the o-ring. I guess that the encoders are very sensitive and this little hole was being felt. I replaced the o-ring and the loss of control problem and the random loops problem went away. Just a thought.
  2. The way I learned it was, loops on the bottom means bad tension on the top. Before you twist anything, if you have an extra bobbin case, try that one with the same thread and see if you get loops. I check e-v-e-r-y bobbin I use with a TOWA tool because I get so frustrated with tension issues. And you would think that prewound bobbins would be consistent, and they are...... mostly. I check each one. If no extra bobbin case, try this: Try tightening (rightsy-tightsy) your top tension a quarter turn then test. Repeat until you get it the way you like it
